All explanations reflect real system behavior, configuration options, and operational logic described in the documentation, including routing, billing, SIP signaling, CDR handling, alarms, and system parameters.
Table of Contents
1. What is VOS3000 Soft switch?
VOS3000 is a carrier-grade VoIP soft switch platform designed for telecom operators and VoIP service providers. It integrates call control, routing management, billing, account management, SIP signaling, and CDR processing into a unified system.
2. Which operating system is required for VOS3000?
According to the manual, VOS3000 is deployed on Linux server environments. Stable Linux distributions are recommended to ensure performance, reliability, and compatibility with system services.
3. What protocols are supported by VOS3000?
VOS3000 supports SIP and H.323 signaling protocols. These protocols are used for call setup, termination, authentication, and interoperability with gateways, carriers, and SIP devices.
4. How does call routing work in VOS3000?
Call routing in VOS3000 is prefix-based. The system compares destination number prefixes with routing rules, gateway priorities, rate tables, and availability to determine the most suitable route.
5. Does VOS3000 support Least Cost Routing (LCR)?
Yes. VOS3000 includes Least Cost Routing functionality that selects routes based on the lowest rate per second, while also considering gateway priority and routing quality.
6. What is a routing gateway in VOS3000?
A routing gateway represents an outbound route toward a vendor or carrier. It includes IP address, protocol settings, line limits, billing account association, and routing priority.
7. What is a mapping gateway?
A mapping gateway represents inbound traffic sources. It maps incoming calls from a specific IP or device to an account and applies authentication, billing, and routing rules.
8. What is a gateway group?
Gateway groups are used to combine multiple routing and mapping gateways into a single logical group, allowing capacity control, routing restrictions, and simplified management.
9. Can VOS3000 limit concurrent calls?
Yes. VOS3000 allows administrators to set line limits at gateway, gateway group, and account levels to restrict the number of concurrent calls.
10. How does VOS3000 handle call failover?
If a routing gateway fails or becomes unavailable, VOS3000 automatically attempts the next available route based on priority and routing rules.
11. How does VOS3000 generate Call Detail Records (CDR)?
VOS3000 generates a CDR for each call attempt. The record includes caller number, callee number, start time, end time, duration, gateway IDs, billing mode, and termination reason.
12. Where are CDR files stored?
When enabled, CDRs are written to text files in the CDR directory under the VOS3000 installation path. Files are generated hourly using a timestamp-based naming format.
13. Does VOS3000 support real-time billing?
Yes. VOS3000 performs real-time billing by deducting call charges from account balances during the call. Calls are terminated automatically if balance limits are exceeded.
14. What billing modes are supported?
Billing can be performed by phone number, gateway ID, or phone card, depending on account configuration and call source.
15. What is an account in VOS3000?
An account represents a customer or vendor entity. It controls balance, billing rules, routing permissions, credit limits, and authentication parameters.
16. What is an agent account?
Agent accounts can have sub-accounts. Charges incurred by sub-accounts are aggregated to the agent account, allowing hierarchical billing structures.
17. How are rate tables used?
Rate tables define call pricing based on destination prefixes. They are assigned to accounts and routing gateways to calculate call charges.
18. Can VOS3000 block specific destinations?
Yes. Forbidden prefixes can be configured to block calls to specific destinations, such as premium or high-risk numbers.
19. Does VOS3000 support number translation?
VOS3000 supports number transformation rules that allow adding, removing, or replacing digits before routing or billing.
20. How does VOS3000 authenticate calls?
Authentication can be performed using SIP credentials or IP-based authentication, depending on the gateway and account configuration.
21. Does VOS3000 support SIP OPTIONS monitoring?
Yes. SIP OPTIONS messages can be sent periodically to detect gateway availability. If a gateway fails OPTIONS checks, it is temporarily excluded from routing.
22. What codecs are supported?
VOS3000 supports common VoIP codecs such as G.711 and G.729, configurable at gateway and protocol levels.
23. How does VOS3000 handle NAT?
NAT traversal features include keep-alive messages, SDP address handling, and media proxy settings to ensure stable SIP communication.
24. What is call duration precision?
The system allows configuration of billing time precision, determining how call duration is rounded for billing purposes.
25. Can VOS3000 restrict calls by time?
Yes. Work calendars and time-based rules allow administrators to restrict calls during specific hours or non-working periods.
26. What alarm features are available?
VOS3000 includes alarm monitoring for gateway status, balance thresholds, system errors, and abnormal traffic conditions.
27. How are logs managed?
System logs and history alarm tables are stored in the database and can be accessed through the data maintenance interface.
28. Can VOS3000 prevent overdraft?
Anti-overdraft mechanisms prevent accounts from exceeding allowed balances by checking credit availability before and during calls.
29. What is bilateral reconciliation?
Bilateral reconciliation compares billing amounts between customers and vendors to detect deviations automatically.
30. Does VOS3000 support LRN lookup?
Yes. For number portability, VOS3000 supports LRN queries to external servers and can route calls based on returned LRN numbers.
31. Can VOS3000 forward call status via HTTP?
HTTP call status notifications can be enabled to send call events to external systems for integration purposes.
32. What is rate limiting in VOS3000?
Rate limiting restricts the number of call attempts within a defined period to protect the system from abuse or attacks.
33. Does VOS3000 support SIP header manipulation?
Yes. SIP headers such as P-Asserted-Identity and P-Preferred-Identity can be passed through, modified, or replaced based on configuration.
34. How does VOS3000 handle call failures?
Call failure causes are recorded in CDRs and categorized by server-side, SIP device, or network-related termination reasons.
35. What is a package in VOS3000 billing?
Packages define free duration, free money amount, rent period, and minimum consumption rules applied before standard billing.
36. How are packages prioritized?

Why VOS3000 Server getting restarted daily auto, Know easy Solution
Hello,
Table of Contents
if you are using VOS3000 2.1.8.0 or 2.1.8.05 sometime VOS3000 server went down/restart/reboot auto daily in a fixed time and VOS3000 server starts but vos3000 softswitch shows offline or softswitch stays offline or red on softswich.
reason that happen in VOS3000 installation script have one cronjob where it have a command line to reboot/restart the server everyday, so according to timezone the vos3000 server reboot everyday sametime and when it starts sometime in cloud server or small vps or low resource server have problem for auto start the mbx3000 which is Softswitch module in VOS3000, so after server restart and come back online mbx3000 stays stopped and shows softswitch offline in VOS3000 client software you will see red in mbx3000 status icon where it suppose to be green, in that case need to login to ssh and start the mbx3000 manually by command line “service mbx3000d restart” or “service mbx3000d start” VOS3000 Server getting restarted
but the real solution is stop that cronjob, so the server will not get rebooted everyday at sametime. for centos7 or centos6 server command for cronjob edit “crontab -e” then it will open a linux editor and remove the command line and save. VOS3000 Server getting restarted
Also you can add auto cronjob if incase mbx3000 goes offline the cronjob will check automatically and start the mbx3000 in server, for that you will need a custom cronjob whcih will check the status of mbx3000/softswitch and will start it auto if that is offline or down. VOS3000 Server getting restarted
if you need more help or details for vos3000 then contact in whatsapp: +8801911119966 (only whatsapp text)
VOS3000 latest versions like 21805 or 21907 work mainly on Centos7, so you will need to use Centos7 as OS for VOS3000 2.1.8.05 or 2.1.9.07 Versions. Any Centos7 is ok but will need accurate kernel to work the emp, else emp will fail sometime.
any Centos7 is ok but if you still ask me then you can use this ISO which is small and easy to install

VOS3000 API (2.1.9.07) Connection, Common issues, VOS3000 API easy Guide
Hello,
Table of Contents
in earlier VOS3000 versions for VOS3000 API Connectivity we needed few extra modules, like VOS3000 3rd Party (rpm) or VOS3000 Web External (rpm) to be installed at the VOS3000 server but in VOS3000 2.1.9.07 those are auto builtin with the server and no need any extra rpm file to be installed, for example 2.1.6.00 version had extra files named: vos3000-webexternal-2.1.6-00.i586.rpm and vos3000-webthirdparty-2.1.6-00.i586.rpm to be installed in VOS3000 2.1.6.00 server, so APi module worked with those api calls, but now no need to install anything like that, VOS3000 2.1.9.07 version have all builtin, still many people fail to connect the API. Here is some common issues i want to mention:
in VOS3000 API manual (2.1.9.07) you will see everywhere it mentioned http://ip:8080/external/server – but where is actually the VOS3000 2.1.9.07 by default http port is 9090, so correct URL will be http://ip:9090/external/server , many people get confusion on the URL and fail to work on it
VOS3000 2.1.9.07 version they developed a Test interface from where you can see if the VOS3000 is working or not with the API calls, what are the return codes coming, but you have to allow your local ip (computer ip) in the VOS3000 web access control to make that link workable and only then you can test…
this is VOS3000 Web External API Call Test Panel, you Can test api from here if they are working well with server or not, you have to allow VOS server ip also your computer ip to access this ip….
This is the place where you have to allow the ips, to activate both real api call and test call as well, /external/test/ – this place for test the API CALL. now many people had issue with ipv4 and ipv6, when they try with localhost, 127.0.0.1 – the server try with ipv6 to connect with the VOS3000, so i have also added 0:0:0:0:0:0:0:1 – which represent ipv6, so if you in case have issue to connect with ipv4 then this will work too.
This you will see after you test the API Calls, the response will shown with retCode (return code), and you will see if thats worked with your VOS3000 server or not, you will able to see changes in your VOS3000 main server.
here in from SSH i am trying to get real data for API call to get all customers name, the result also came with all customers name, you can see names are showing after return code.
Here you can see exact those accounts are in my server which the API got from my server in SSH.
So overall VOS3000 2.1.9.07 Have most easiest way to connect the API, you can develop your own VOS3000 complete web management solution if you want also you can use any billing software if you needed. The VOS3000 api manual is in chinese, so many people get confusion but this is very easy and all things are builtin, so no need anything extra or any extra pain.
if you need anymore help for VOS3000 API settings, manual, api connection issues, API not working, how to connect api easily or anything you need to know about VOS3000 API for 2.1.9.07 or other version VOS3000 API related things or manuals then knock me in whatsapp: +8801911119966 (Whatsapp only)
