VOS3000 Data Maintenance & Auto‑Cleanup: Important Database Management Guide

As your VOS3000 softswitch processes thousands of calls daily, the MySQL database grows continuously. Without proper VOS3000 data maintenance, old CDRs, logs, and reports consume disk space, slow down queries, and can eventually cause system instability. This guide covers everything you need to know about managing VOS3000 data – from manual cleanup to fully automated maintenance routines.

By the end of this article, you’ll know how to keep your database lean, fast, and reliable for years of operation.

Why VOS3000 Data Maintenance Matters

VOS3000 stores data in multiple MySQL tables that grow daily:

CDR tables – one per day (cdr_YYYYMMDD) – can grow to gigabytes per month under heavy traffic.
System logs – record every user action and system event.
Payment records – all recharge and adjustment history.
Alarm history – past alarms and notifications.
Report data – pre‑computed summaries for quick access.

Without cleanup, you risk:

Running out of disk space (causing MySQL crashes).
Slow CDR queries (waiting minutes for results).
Backup files becoming too large to handle.

Understanding VOS3000 Data Storage Structure

VOS3000 organizes data into separate tables by type and date. This design makes maintenance easier – you can drop or archive entire tables without affecting current operations.

CDR Tables

Located under “System Management > Data Maintenance > CDR Tables”. Each table name ends with a date suffix, e.g., cdr_20250309. The “Data volume” column shows the number of records. Double‑click any table to view its contents.

System Log Tables

Found under “System Management > Data Maintenance > System Log Tables”. These record all user activities – logins, configuration changes, etc. They’re essential for audits but can be purged after a retention period.

History Alarm Tables

Under “System Management > Data Maintenance > History Alarm Tables”. Stores past alarms. Once resolved, alarms move here from current alarm list.

Payment Record Tables

Under “System Management > Data Maintenance > Payment Record Tables”. All financial transactions are stored here permanently or until purged.

Data Report Tables

Under “System Management > Data Maintenance > Data Report Tables”. Pre‑generated reports (daily summaries) – can be safely deleted if you regenerate reports on demand.

Other Income Report Tables

Under “System Management > Data Maintenance > Other Income Report Tables”. Contains package rent, monthly fees, and other non‑call income records.

Manual Data Cleanup Methods

For one‑time or occasional cleanup, you can manually delete old data through the web interface:

Navigate to System Management > Data Maintenance.
Select the table category (e.g., CDR Tables).
Click Filter to show all tables.
Check the boxes next to tables older than your retention period.
Click Delete and confirm.

⚠️ Warning: Deleted data cannot be recovered. Ensure you have verified backups before deleting anything.

Automating VOS3000 Data Cleanup – VOS3000 Data Maintenance

Manual cleanup is error‑prone. VOS3000 includes a powerful auto‑cleanup feature that automatically removes old data based on your rules.

Enabling Auto‑Cleanup

Go to System Management > Data Maintenance > Automatically Cleanup. Here you can configure retention periods for each data type:

CDR tables – keep for X days, then delete.
System log tables – keep for X days.
History alarm tables – keep for X days.
Payment record tables – keep for X days (be careful – financial records may need longer retention for legal reasons).
Data report tables – keep for X days.
Other income report tables – keep for X days.

You can also enable automatic cleanup of:

Accounts – delete accounts that have been inactive/expired for X days.
Gateways – delete gateways belonging to deleted accounts.
Phones – delete phones belonging to deleted accounts.

How Auto‑Cleanup Works

Once enabled, a background process runs daily (typically at low‑traffic hours) and:

Identifies tables older than the configured retention period.
Drops those entire tables (fastest method).
Logs the action in system logs for audit.
If configured, deletes orphaned accounts/gateways/phones.

⚠️ Important: Auto‑cleanup deletes entire tables, not individual rows. This is extremely fast and efficient but means you cannot keep partial months – it’s all or nothing per table.

Recommended Retention Periods – VOS3000 Data Maintenance

Based on typical VoIP operations, here are sensible starting points:

Data Type	Retention Period	Reason
CDRs	90 days	Enough for customer disputes and traffic analysis; older data can be archived externally.
System logs	30 days	Security audits rarely need older logs; export if longer retention required.
History alarms	60 days	Alarm patterns over two months help identify recurring issues.
Payment records	365 days (or longer for compliance)	Financial records may need 1‑7 years depending on local laws – adjust accordingly.
Data reports	30 days	Reports can be regenerated from CDRs if needed.

Backup Strategy Before Cleanup – VOS3000 Data Maintenance

Before enabling auto‑cleanup or running manual deletes, ensure you have reliable backups:

Daily mysqldump of the entire VOS3000 database (compressed).
Binary logs for point‑in‑time recovery (if you need to restore to a specific moment).
Off‑site storage – keep backups on a different server or cloud storage.

Test your backups regularly by restoring to a test environment.

Monitoring Disk Space

Even with auto‑cleanup, monitor disk usage:

Use System Management > Server Monitor to see disk usage trends.
Set up Disk Alarm under Alarm Management to notify you when disk usage exceeds thresholds (e.g., 80%, 90%).
Check MySQL data directory size periodically: du -sh /var/lib/mysql

Advanced: Archiving Old CDRs

If you need to keep CDRs longer than auto‑cleanup allows, consider archiving:

Export old CDR tables to CSV or SQL files.
Compress and store them in a secure location.
Delete the tables from the live database (either manually or via auto‑cleanup).
If you need to query archived data, import into a separate reporting database or use command‑line tools.

VOS3000 does not include built‑in archival tools, but you can script this using mysqldump and cron.

Frequently Asked Questions (VOS3000 Data Maintenance)

Will auto‑cleanup delete accounts that still have active phones?

No. Auto‑cleanup only deletes accounts that have been expired and have no associated active phones, gateways, or bind numbers. It checks dependencies before deleting.

Can I recover data after auto‑cleanup deletes it?

Not from the live system. You must restore from backups if you need deleted data. This is why testing your backup restoration process is critical before enabling auto‑cleanup.

Does deleting CDR tables affect current calls?

No. VOS3000 writes CDRs to a temporary table and moves them to the daily table after the call ends. Deleting old tables has no impact on ongoing calls.

Why are my CDR tables not being deleted even though auto‑cleanup is enabled?

Check that the retention period is set correctly and that the cleanup process is running (system logs will show cleanup actions). Also ensure that the tables are indeed older than the retention period – auto‑cleanup runs daily, so tables become eligible only after the configured number of days have passed since their creation.

Can I keep payment records forever while auto‑deleting CDRs?

Yes. Each data type has independent retention settings. Set payment records to a high value (e.g., 3650 days) and CDRs to a lower value (e.g., 90 days).

Conclusion

Proper VOS3000 data maintenance ensures your softswitch runs smoothly, queries stay fast, and disk space never becomes a crisis. Whether you prefer manual control or fully automated cleanup, VOS3000 provides the tools you need. Start with conservative retention periods, monitor the results, and adjust as you gain confidence.

VOS3000 Architecture & Design: Full Core Components and Call Flow Properly Explained

Understanding VOS3000 architecture is essential for anyone deploying or managing this carrier‑grade softswitch. Whether you’re troubleshooting call failures, planning capacity, or optimizing performance, knowing how the system components interact helps you make better decisions and avoid common pitfalls.

In this comprehensive guide, we’ll break down the VOS3000 architecture into its core modules, explain the end‑to‑end call flow, and give you the knowledge you need to run a stable, scalable VoIP platform.

Core Components of VOS3000 Architecture

The VOS3000 softswitch is built on a modular architecture where each component handles specific functions. Understanding these modules helps you identify where problems occur and how to scale your system effectively.

1. VOS3000 Softswitch Engine

The heart of the system – a high‑performance signaling and control engine that handles:

SIP and H.323 signaling processing – registration, invite, bye, etc.
Call routing and gateway selection – using longest prefix match, priority, and real‑time metrics (ASR/ACD).
Real‑time billing and rating – applies rate cards, checks balances, and manages prepaid/postpaid logic.
CDR generation – creates detailed call records for downstream billing and reporting.

2. Media Gateway (MediaProxy)

Manages the RTP (audio) streams between callers and callees. It can operate in different modes depending on your needs: VOS3000 architecture

Bypass mode – RTP flows directly between endpoints (lowest latency, minimal CPU load).
Proxy mode – Audio passes through VOS3000 for recording, transcoding, or NAT traversal (higher CPU but more features).
Mixed mode – System decides automatically based on network conditions and device capabilities.

3. MySQL Database

The persistent storage layer that holds all configuration and historical data:

Accounts, rates, and packages – cached in memory for fast access.
Gateways and routing rules – defines how calls enter and leave your network.
CDR records – partitioned daily (cdr_YYYYMMDD) for performance and easy purging.
System logs and alarms – historical events for troubleshooting and auditing.

4. Web Management Interface

An Apache/PHP‑based GUI that allows administrators to configure every aspect of the system – from rate management to user permissions. It communicates with the softswitch engine via internal APIs.

5. VOS3000 Client

A Windows‑based desktop application for real‑time monitoring and advanced configuration tasks that are not available in the web interface (e.g., live call tapping, detailed gateway status).

Understanding Gateway Types in VOS3000

VOS3000 uses two distinct gateway types, and confusing them is a common source of routing errors. Here’s the difference:

Mapping Gateway (Ingress)

Receives calls from upstream providers or customers. Each mapping gateway is linked to a billing account and determines which routing gateways can be used. It also controls caller permissions, black/white lists, and media settings.

Routing Gateway (Egress)

Sends calls out to termination partners. Routing gateways have prefix matching, priority settings, and are linked to clearing accounts for cost tracking. They also handle features like prefix stripping/adding, call duration limits, and failover logic.

VOS3000 Call Flow Architecture (VOS3000 architecture)

Here’s a step‑by‑step breakdown of what happens when a call enters your VOS3000 system:

Incoming INVITE arrives at the softswitch from a mapping gateway (or registered phone).
Authentication – System verifies the gateway IP, checks if the caller is allowed, and validates any digest credentials.
Rate lookup – Using the longest prefix match on the dialed number, the system finds the appropriate rate and checks if the caller is authorized for that call type (local, domestic, international).
Account verification – Checks the linked account’s balance, overdraft limit, and expiry date. If the account uses packages, free minutes are consumed first.
Routing selection – Based on the destination prefix, the system compiles a list of eligible routing gateways, sorts them by priority, ASR, ACD, and current load, then tries them in order until one answers or all fail.
Outgoing call – Softswitch sends an INVITE to the selected routing gateway, applying any configured rewrite rules (caller/callee transformation).
Media path establishment – Depending on media proxy settings, RTP flows directly between endpoints or through the media proxy (for NAT, recording, or transcoding).
CDR generation – After call termination, a CDR is written to the database and made available for real‑time reports and downstream billing systems.

Database Architecture and Data Management

VOS3000 uses MySQL with a carefully designed schema to handle high traffic volumes. Key points:

CDR Table Partitioning

CDRs are stored in daily tables (e.g., cdr_20250309). This prevents any single table from growing too large, keeps queries fast, and simplifies data purging.

Configuration Caching

Critical configuration (accounts, rates, gateways) is loaded into shared memory at startup and updated dynamically when changes are applied. This ensures real‑time performance without hitting the database on every call.

Auto‑Cleanup Mechanisms

System parameters control how long historical data is retained. Regular cleanup prevents disk space exhaustion and maintains database performance.

High‑Level Design Considerations

Separate signaling and media – For high‑traffic deployments, run the softswitch engine and media proxy on separate servers to distribute load.
Database replication – Implement master‑slave replication to protect against data loss and enable quick failover.
Network topology – Ensure low latency between all components; RTP jitter and packet loss directly impact call quality.
Redundancy – Consider deploying a hot‑standby softswitch for automatic failover (disaster recovery).

Frequently Asked Questions (VOS3000 architecture)

What is the difference between mapping gateway and routing gateway?

Mapping gateways receive calls into the system and are linked to billing accounts. Routing gateways send calls out to termination partners and are linked to clearing accounts for cost tracking. Think of mapping as “who pays you” and routing as “who you pay.”

Does VOS3000 support transcoding?

Yes, VOS3000 supports codec transcoding through the media proxy. Common codecs like G.729, G.711, GSM, and iLBC can be converted. However, transcoding increases CPU usage, so plan capacity accordingly and consider using it only when necessary.

How does VOS3000 handle high concurrent calls?

VOS3000 uses an event‑driven architecture that can handle thousands of concurrent calls on properly sized hardware. Key factors are CPU speed for signaling, RAM for caching (accounts/routes), and network bandwidth for RTP. Separating media proxy onto dedicated hardware further increases capacity.

Can I run VOS3000 on a virtual machine?

Yes, VOS3000 runs well on virtualized environments (VMware, KVM, Hyper‑V) for moderate traffic loads. For carrier‑grade traffic (500+ concurrent calls), bare metal is recommended to avoid CPU steal time and network latency introduced by hypervisors.

Conclusion

Understanding VOS3000 architecture helps you deploy more stable platforms, troubleshoot faster, and scale effectively. Whether you’re running a small operation or a carrier‑grade service, knowing how the components fit together is essential for long‑term success.

VOS3000 Call Termination Reasons Dictionary: Important Full Reference Guide

March 8, 2026March 8, 2026 king

VOS3000 Call Termination Reasons Dictionary: Important Full Reference Guide – Call End Reason

When troubleshooting call failures in VOS3000, the termination reason shown in CDRs is your most valuable diagnostic tool. However, many of these reasons are cryptic or misunderstood. This comprehensive VOS3000 termination reasons dictionary explains every possible call end code – both server‑generated and those received from connected devices.

Bookmark this page for quick reference whenever you encounter unexpected call failures.

How VOS3000 Call Termination Reasons Records

Every CDR in VOS3000 includes a termination reason field. This value tells you exactly why the call ended – whether it was rejected, timed out, hung up normally, or failed due to an error. Reasons come from three sources:

Server‑side – generated by the VOS3000 softswitch itself
H.323 device – received from the far‑end H.323 gateway or terminal
SIP device – received from the far‑end SIP equipment (as response codes)

Understanding these codes helps you pinpoint whether the problem is with your configuration, your carrier, or the destination network.

Server‑Side VOS3000 Call Termination Reasons (VOS3000 Generated)

These reasons are created by the VOS3000 softswitch when it decides to terminate a call. They often indicate configuration issues, resource limitations, or policy enforcement.

Termination Reason	Description	Typical Cause
Response timeout	The called party did not answer within the configured timeout period.	Phone offline, network congestion, or wrong routing gateway.
Protocol limit	The server cannot process this protocol type.	Mixing SIP and H.323 incorrectly; incompatible protocol settings.
Connection timeout	No response to SIP messages after multiple retries.	Far end down, firewall blocking, or network issues.
Busy	The called number is busy.	Destination line engaged; call forwarded to busy tone.
Account locked	The billing account is disabled.	Account manually locked, expired, or parent agent locked.
Session timeout	SIP session timer expired (no re‑INVITE received).	Far end stopped responding; network failure.
Caller’s number restricted	Caller number length exceeds allowed limit.	Wrong rewrite rule; caller ID too long for carrier.
Called number restricted	Callee number length exceeds allowed limit.	Incorrect dialing; number too long/short.
Proceeding timeout	No response after initial SETUP/INVITE.	Routing gateway not responding; carrier down.
Caller’s number prefix restricted	Mapping gateway rejects caller prefix.	Caller ID blocked by gateway settings.
Unregistered	Terminal not registered and not allowed to call.	Dynamic gateway/phone not registered.
Called number locked	The destination number is locked in the system.	Phone locked via web interface.
Called number prefix restricted	Routing gateway rejects callee prefix.	Carrier does not terminate that prefix.
Caller locked	The calling device is locked.	Gateway/phone locked in configuration.
Connection establishment timeout	Call not established within mapping gateway timeout.	Media path failure; far end not responding.
Account expired	The billing account has passed its expiry date.	Customer did not recharge on time.
Connection limit exceeded	Maximum concurrent calls reached for this gateway/account.	Too many simultaneous calls; need more capacity.
Forcible hang‑up	Server disconnected the call (admin action).	Admin clicked “disconnect” in client.
Account disabled	The account is disabled (not just locked).	Account marked as disabled by admin.
The called not online	No suitable device to receive the call.	No matching routing gateway; phone offline with no forwarding.
No‑answer forwarding by the caller	Caller‑side forwarding on no‑answer activated.	Caller set CFNR; call redirected.
Timed forwarding	Call matched time‑based forwarding rule.	Forwarding based on time of day.
On‑busy forwarding	Call matched busy forwarding rule.	Destination busy; forwarded.
No‑answer forwarding by the called	Callee‑side CFNR activated.	Phone not answered; forwarded.
Forwarding loop	Forwarding rules created an infinite loop.	Misconfigured call forwarding.
Call forwarding by the called	Unconditional call forwarding on callee side.	Phone set to forward all calls.
Do‑not‑disturb from the called	Callee has DND enabled.	Phone in DND mode.
Session closed by the called	Called party closed TCP connection without BYE.	Device crash; network disconnect.
Session closed by the caller	Caller closed TCP connection without BYE.	Device crash; network disconnect.
Illegal call	Call from unauthorized IP and unregistered number.	Hacker attempt; misconfigured gateway.
No matching rate	No rate found for the dialed number.	Missing rate prefix; incomplete rate card.
No matching account	No billing account linked to the caller.	Mapping gateway not linked to account.
Insufficient balance	Account balance below zero (including overdraft).	Customer ran out of credit.
Call restriction	Call prevented by phone/gateway restrictions.	International blocking; blacklist.
Hang‑up by the called	Called party sent normal BYE.	Normal call end.
Hang‑up by the caller	Caller sent normal BYE.	Normal call end.

SIP Device Termination Reasons (Response Codes) – VOS3000 Call Termination

When a call fails because of the remote SIP device, VOS3000 records the SIP response code received. Here are the most common ones:

SIP Code	Reason Phrase	Meaning
401	Unauthorized	Authentication failed – wrong password or missing credentials.
403	Forbidden	Call rejected by remote side (blacklist, policy).
404	Not Found	Number does not exist on remote network.
486	Busy Here	Destination line busy.
487	Request Terminated	Call cancelled (e.g., caller hung up before answer).
488	Not Acceptable Here	Codec mismatch – no common codec.
503	Service Unavailable	Remote server overloaded or down.
504	Server Time‑out	Gateway did not respond in time.
603	Decline	Call rejected by user (DND, reject).

H.323 Device Termination Reasons – VOS3000 Call Termination

H.323 devices return Q.931 cause codes. Common ones include:

Q.931 Cause	Description	Typical Cause
1	Unallocated number	Number not in service.
3	No route to destination	Network unreachable.
16	Normal call clearing	Normal hang‑up.
17	User busy	Destination busy.
18	No user responding	No answer (ring timeout).
21	Call rejected	Rejected by remote side.
22	Number changed	Number ported; redirect.
27	Destination out of order	Far end equipment failure.
28	Invalid number format	Wrong dialed digits.
34	No circuit/channel available	All trunks busy.
38	Network out of order	Carrier network failure.
41	Temporary failure	Transient network error – retry.
42	Switching equipment congestion	Overload at exchange.
47	Resource unavailable	Codec or channel resource issue.

How to Use This Information for Troubleshooting – VOS3000 Call Termination

When you see a call failure, follow this process:

Check the termination reason in the CDR.
Identify the source – server, SIP, or H.323.
Look for patterns – does it happen to one prefix, one gateway, or all calls?
Examine logs – use “Call Analysis” in the VOS3000 client to see the full signaling exchange.
Check configurations – rates, blacklists, number lengths, account balances.
Test with routing analysis – simulate the call to see which gateway would be chosen.

Frequently Asked Questions (VOS3000 Call Termination)

What does “No matching rate” mean?

This means the dialed number’s prefix did not match any rate in the rate group assigned to the caller’s account. You need to add the missing rate prefix or adjust the caller’s rate group.

Why do I see “Illegal call” in CDRs?

“Illegal call” means the incoming IP address was not recognized as a valid mapping gateway, and the caller number did not match any registered phone. This is often a hacking attempt – block the IP immediately and review your firewall rules.

What causes “488 Not Acceptable Here”?

This SIP error means the remote gateway does not support any of the codecs offered by your system. Check codec settings on both sides and ensure at least one common codec (e.g., G.729, G.711) is enabled.

How do I distinguish between a local hang‑up and a remote hang‑up?

The CDR field “Hangup side” tells you: 0 = caller, 1 = callee, 2 = server. Combined with termination reason, you can see exactly who ended the call and why.

My CDR shows “Response timeout” – what should I check?

First, verify the routing gateway is online and reachable. Then check if the remote side is answering other calls. If only specific prefixes fail, the carrier may not be sending progress signals – increase the timeout settings in the routing gateway configuration.

Conclusion – VOS3000 Call Termination

Understanding VOS3000 termination reasons is the fastest path to resolving call failures. Bookmark this reference and refer to it whenever you encounter an unfamiliar code. With practice, you’ll be able to diagnose most issues in seconds.

VOS3000 Disaster Recovery & Backup Setup: Master‑Slave High Availability Important Guide

March 8, 2026March 11, 2026 king

VOS3000 Disaster Recovery & Backup Setup: Master‑Slave High Availability Important Guide

In the VoIP business, downtime means lost revenue and angry customers. A proper VOS3000 disaster recovery plan ensures that your softswitch keeps running even if the primary server fails. Whether you’re serving hundreds or thousands of concurrent calls, a master‑slave high availability (HA) setup is the industry standard for reliability.

In this guide, we’ll walk you through the complete process of configuring VOS3000 disaster recovery, including prerequisites, step‑by‑step setup, testing, and best practices.

Why VOS3000 Disaster Recovery Matters

VOS3000 stores all critical data – accounts, rates, CDRs – in a MySQL database. If the server crashes, you lose not only current calls but also the ability to route new traffic. A disaster recovery setup provides:

Automatic failover – slave takes over within seconds
Data redundancy – real‑time replication prevents data loss
Minimal manual intervention – no need to reconfigure everything

Understanding VOS3000 High Availability Architecture

VOS3000 uses a master‑slave replication model:

Master server – handles all live calls, writes CDRs, and accepts configuration changes.
Slave server – constantly synchronizes data from the master and stands ready to take over.
Shared virtual IP – clients and gateways connect to a single IP that floats between servers.

When the master fails, the slave detects the outage, activates its softswitch services, and assumes the virtual IP. Calls in progress may drop, but new calls are processed immediately.

Prerequisites for Disaster Recovery Setup

Before you begin, ensure you have:

Two identical servers with VOS3000 installed (same version, same CentOS/RHEL release).
Dedicated private network between them for replication (low latency).
Same MySQL root password on both servers.
Virtual IP that can be moved between servers (requires `keepalived` or similar).
Sufficient disk space on both servers (mirroring CDR storage).

Step‑by‑Step VOS3000 Disaster Recovery Configuration

Step 1: Prepare the Master Server

On the master server, enable binary logging and set a unique server ID:

# Edit /etc/my.cnf

[mysqld]

log-bin=mysql-bin server-id=1 binlog-do-db=vos3000db # your actual database name

Restart MySQL and create a replication user:

CREATE USER 'replica'@'slave_ip' IDENTIFIED BY 'strong_password';
GRANT REPLICATION SLAVE ON *.* TO 'replica'@'slave_ip';
FLUSH PRIVILEGES;

Record the master status:

SHOW MASTER STATUS;

Step 2: Prepare the Slave Server

Stop MySQL, copy the master data to slave (using `mysqldump` or `xtrabackup`), then configure slave:

[mysqld]
server-id=2
relay-log=relay-log

Start MySQL and set up replication:

CHANGE MASTER TO
  MASTER_HOST='master_ip',
  MASTER_USER='replica',
  MASTER_PASSWORD='strong_password',
  MASTER_LOG_FILE='mysql-bin.xxxxxx',
  MASTER_LOG_POS=xxxx;
START SLAVE;

Verify with SHOW SLAVE STATUS\G – both Slave_IO_Running and Slave_SQL_Running should be “Yes”.

Step 3: Configure Virtual IP with Keepalived

Install and configure keepalived on both servers. Example `/etc/keepalived/keepalived.conf` (master):

vrrp_instance VI_1 {
    state MASTER
    interface eth0
    virtual_router_id 51
    priority 101
    advert_int 1
    virtual_ipaddress {
        192.168.1.100/24   # your virtual IP
    }
}

On slave, change state to BACKUP and priority to 100. Restart keepalived.

Step 4: Configure VOS3000 Services for HA

On both servers, ensure that VOS3000 listens on the virtual IP (edit network settings or use IP aliasing). In the VOS3000 web interface, set the “Local IP” of gateways and phones to the virtual IP. This way, after failover, devices reconnect automatically.

Step 5: Test Failover

Simulate a master failure by stopping the master server or the VOS3000 process. Verify that:

The virtual IP moves to the slave.
New calls can be established.
CDRs are written on the slave (and later synced back when master recovers).

Monitoring Disaster Recovery Status

VOS3000 provides built‑in tools to monitor HA status:

Disaster Tolerance Status – shows current master, slave, and sync lag.
Disaster Tolerance Data – verify data consistency between servers.
Disaster Tolerance Equipment – manage registered HA pairs.

Access these via the web interface under “Disaster Recovery System”.

Backup Strategy in a DR Setup

Even with replication, you need regular backups:

Daily mysqldump of the entire database (compressed, stored off‑server).
Binary logs – keep them for point‑in‑time recovery.
Configuration files – backup `/etc` and VOS3000 config directories.

Common Pitfalls and Solutions

Replication lag – caused by slow network or heavy writes. Monitor with `Seconds_Behind_Master`.
Split‑brain – both servers think they are master. Use fencing (STONITH) or careful keepalived config.
Different MySQL versions – always use the same version on both servers.
Firewall blocking replication port (3306) – open between servers.

Frequently Asked Questions (VOS3000 Disaster Recovery)

Does VOS3000 support active‑active clustering?

No, VOS3000 officially supports active‑passive master‑slave replication. Active‑active is not recommended because of potential conflicts in real‑time billing and CDR sequence.

How long does failover take?

With keepalived and properly tuned services, failover typically completes within 5‑10 seconds. Calls established before failure may drop, but new calls are processed immediately.

Will I lose CDRs during failover?

If replication is synchronous enough, most CDRs are already on the slave. Any CDRs that were in memory but not yet written to the master’s database may be lost. To minimize loss, set `sync_binlog=1` and `innodb_flush_log_at_trx_commit=1` on master.

Can I use a different hardware for slave?

Yes, but it’s recommended to use identical hardware to ensure consistent performance during failover. If the slave is weaker, it may struggle to handle full traffic load.

How do I switch back to the original master after repair?

Repair the master, ensure it has caught up with the slave (re‑sync if needed), then manually promote it back using a controlled switchover procedure to avoid split‑brain.

CPS Control in VOS3000, Rate Limit in VOS3000, VOS3000 calls per second control

CPS Control in VOS3000 – Complete Gateway Rate Limit Easy Guide

🚦 CPS Control in VOS3000 – Complete Gateway Rate Limit Configuration Guide

CPS Control in VOS3000 is one of the most important advanced configurations for managing high traffic, junk calls, CC traffic and vendor/client overload situations.

VOS3000 is a carrier-grade VoIP softswitch platform widely used for telecom routing, wholesale VoIP, calling card systems and enterprise SIP routing. It is known for stability, high concurrency support and flexible gateway configuration.

📌 What is CPS Control in VOS3000?

CPS means Calls Per Second. In VOS3000, Calls Per Second Control allows administrators to limit how many calls a specific gateway can generate per second.

By default, VOS3000 supports around 1200 CPS which is suitable for large telecom operations. However, sometimes:

⚠ Vendor sends excessive burst traffic
⚠ Client generates junk traffic
⚠ CC attack creates call flood
⚠ System gets overloaded due to abnormal spikes

In these cases, CPS Control becomes critical.

⚙️ Where to Find CPS Control in VOS3000?

In VOS3000 interface:

🔹 Client Gateway = Mapping Gateway
🔹 Vendor Gateway = Routing Gateway

Step to Configure:

Go to Gateway Management
Edit Mapping Gateway (Client) OR Routing Gateway (Vendor)
Open the last tab → Others
Before the end, you will see Rate Limit

🔔 Rate Limit = CPS Control in VOS3000

Once enabled and value inserted, system will enforce CPS restriction for that specific gateway.

📊 Where to See CPS Live Statistics?

After enabling CPS Control:

📈 Online Mapping Gateway → You will see Calls Per Second tab
📈 Online Routing Gateway → CPS column becomes visible

This gives real-time gateway-wise CPS monitoring and better traffic analytics.

🔥 Why CPS Control is Important?

Large volume VoIP traffic often includes:

🚫 Junk Traffic
🚫 Fraud Attempts
🚫 Call Burst from Vendor
🚫 CC (Call Center) aggressive traffic
🚫 Auto dialer floods

If CPS is not limited:

⚠ Server CPU spikes
⚠ Database overload
⚠ Call drop issues
⚠ Vendor instability
⚠ Client dispute

Proper CPS tuning ensures:

✅ Stable routing
✅ Controlled traffic burst
✅ Gateway-wise isolation
✅ Better monitoring
✅ Enterprise-grade traffic engineering

⚡ Best CPS Strategy in VOS3000

There is no universal number. It depends on:

🔹 Server hardware
🔹 Network quality
🔹 Vendor capacity
🔹 Client behavior
🔹 Average Call Duration

Recommended practice:

✔ Start with lower CPS (20–50 for risky vendors)
✔ Increase gradually after monitoring
✔ Separate high-volume and low-volume vendors
✔ Never allow unlimited CPS on new gateway

📘 Advanced Technical Understanding

VOS3000 internally processes signaling queues. When CPS exceeds safe processing limits:

Queue latency increases
SIP response delays occur
Memory allocation spikes
System instability risk increases

Rate Limit (Calls Per Second Control) acts as a traffic shaping mechanism at gateway level.

🛡 CPS Control vs System Protection

CPS Control is not firewall. It is traffic shaping inside VOS routing engine.

For complete protection combine:

🔒 Calls Per Second Control
🔒 Proper Server Security
🔒 SSH Port Change
🔒 Strong Root Password
🔒 IP Based Firewall

❓ Frequently Asked Questions (FAQ)

1️⃣ What is default CPS in VOS3000?

Default system CPS is around 1200 but gateway-specific CPS can be configured using Rate Limit.

2️⃣ Is CPS Control per gateway or global?

CPS Control is configured per gateway (Mapping or Routing).

3️⃣ Does CPS affect ASR?

If configured too low, yes. If properly tuned, it improves system stability.

4️⃣ Can CPS prevent CC attacks?

It helps control burst traffic but should be combined with firewall security.

5️⃣ Where exactly is Rate Limit option?

Edit Gateway → Others Tab → Rate Limit (CPS Control).

6️⃣ Should every vendor have CPS limit?

Yes. Even trusted vendors should have reasonable limits to avoid unexpected traffic spikes.

7️⃣ Is CPS visible in monitoring?

Yes. After enabling, Calls Per Second column appears in Online Gateway view.
