Morning Checklist for VOS3000 Operators

Starting each day with a systematic review of your VOS3000 platform sets the foundation for trouble-free operations. This morning checklist ensures you catch overnight issues and prepare for the day’s traffic.

๐ŸŒ… Server Status Verification

Before checking application-specific items, verify that your server infrastructure is healthy:

  • Server Accessibility: SSH and web interface access verified
  • CPU Usage: Check for unusual processor load
  • Memory Status: Verify adequate available RAM
  • Disk Space: Confirm sufficient storage for CDR growth
  • Network Connectivity: Test connectivity to key gateways

The VOS3000 manual documents server monitoring in Section 2.12.10 (Server Monitor), which displays server time, CPU performance, memory performance, disk performance, and network performance metrics.

๐Ÿ” System Log Review (VOS3000 Daily Operations)

๐Ÿ“ก Understanding Media Proxy in VOS3000

Media proxy determines whether RTP (Real-time Transport Protocol) voice packets flow directly between endpoints or through the VOS3000 server. This decision has significant implications for NAT traversal, audio quality, server resource usage, and call reliability.

๐Ÿ“Š VOS3000 Media Proxy Modes

The SS_MEDIAPROXYMODE parameter controls media proxy behavior with four distinct modes:

ModeBehaviorServer LoadBest Use Case
OffNever proxy media; RTP flows directly between endpointsLowestPublic IP endpoints, no NAT issues
OnAlways proxy all media through serverHighestTroubleshooting, maximum control
AutoIntelligent decision based on conditionsVariableMixed environments, recommended
Must OnForced proxy regardless of other settingsHighestSpecific debugging scenarios only

โš™๏ธ Media Proxy Auto Mode Decision Logic (VOS3000 Media Proxy)

When SS_MEDIAPROXYMODE is set to “Auto,” VOS3000 follows a precise decision algorithm to determine whether media proxy is needed:

Media Proxy Decision Steps (Auto Mode):

Step 1: Check if caller or callee MUST have media proxy
        โ”œโ”€โ”€ If gateway/phone has Media Proxy = Must On
        โ””โ”€โ”€ Result: ENABLE media proxy

Step 2: Check if caller or callee has Media Proxy disabled
        โ”œโ”€โ”€ If gateway/phone has Media Proxy = Off
        โ””โ”€โ”€ Result: DISABLE media proxy

Step 3: Check if caller or callee has Media Proxy enabled
        โ”œโ”€โ”€ If gateway/phone has Media Proxy = On
        โ””โ”€โ”€ Result: ENABLE media proxy

Step 4: Check if callee has local ring enabled
        โ”œโ”€โ”€ Local ring requires media proxy for ringback tone
        โ””โ”€โ”€ Result: ENABLE media proxy

Step 5: Check for dynamic registration with encryption
        โ”œโ”€โ”€ If phone/gateway uses dynamic register AND encryption
        โ””โ”€โ”€ Result: ENABLE media proxy

Step 6: Check cross-network routing (SS_MEDIAPROXYBETWEENNET)
        โ”œโ”€โ”€ If caller and callee from different networks
        โ””โ”€โ”€ Result: ENABLE media proxy

Step 7: Check NAT conditions (SS_MEDIAPROXYBEHINDNAT)
        โ”œโ”€โ”€ If phone and gateway in same NAT, SS_MEDIAPROXYSAMENAT = On
        โ”œโ”€โ”€ If phone and gateway in different NAT, one in private network
        โ””โ”€โ”€ Result: ENABLE media proxy

Step 8: Default action
        โ””โ”€โ”€ Result: DISABLE media proxy

๐Ÿ“ก RTP Port Configuration (VOS3000 Media Proxy)

RTP port configuration determines which UDP ports VOS3000 uses for voice media streams. Proper configuration is essential for firewall rules and capacity planning. VOS3000 Media Proxy

๐Ÿ“Š RTP Port Parameters VOS3000 Media Proxy

ParameterDefault ValueDescription
SS_RTP_PORT_RANGE10000,39999UDP port range for RTP media streams
SS_H245_PORT_RANGE10000,39999H.245 port range for H.323 calls
IVR_RTP_PORT40000,47999RTP port range for IVR services

โš™๏ธ RTP Port Sizing Calculation

RTP Port Capacity Planning:

Each concurrent call uses 2 RTP ports (one for each direction)
Port Range: 10000-39999 = 30,000 ports
Maximum Concurrent Calls = 30,000 / 2 = 15,000 calls

However, consider:
- Each port allocation has overhead
- IVR services need separate port range
- H.323 calls share same range

๐Ÿ”‘ SIP Parameters Reference – VOS3000 Media Proxy

SIP parameters control how VOS3000 handles SIP signaling, authentication, and session management. These parameters directly impact call setup success and session reliability.

๐Ÿ“Š Critical SIP Parameters

ParameterDefaultPurpose
SS_SIP_NAT_KEEP_ALIVE_MESSAGEHELLOContent of NAT keep-alive message
SS_SIP_NAT_KEEP_ALIVE_PERIOD30Keep-alive interval in seconds (10-86400)
SS_SIP_NAT_KEEP_ALIVE_SEND_INTERVAL500Interval between sending keep-alives (ms)
SS_SIP_NAT_KEEP_ALIVE_SEND_ONE_TIME3000Number of keep-alives sent per batch
SS_SIP_SESSION_TTL1800Session Timer TTL in seconds
SS_SIP_SESSION_UPDATE_SEGMENT300Session update interval in seconds
SS_SIP_RESEND_INTERVAL0.5,1,2,4,4,4,4,4,4,4SIP message resend intervals (seconds)
SS_SIP_NO_TIMER_REINVITE_INTERVAL7200Max call time for non-timer SIP clients

โš™๏ธ NAT Keep-Alive Configuration

NAT Keep-Alive Purpose:
- Maintains NAT binding for devices behind NAT
- Prevents one-way audio caused by expired bindings
- Essential for devices that don't support SIP Timer

How It Works:
1. VOS3000 sends UDP message to registered device IP
2. Message content = SS_SIP_NAT_KEEP_ALIVE_MESSAGE (default: "HELLO")
3. Sent every SS_SIP_NAT_KEEP_ALIVE_PERIOD seconds (default: 30)
4. This keeps the NAT mapping active

Configuration Example:
SS_SIP_NAT_KEEP_ALIVE_MESSAGE = "HELLO"
SS_SIP_NAT_KEEP_ALIVE_PERIOD = 30
SS_SIP_NAT_KEEP_ALIVE_SEND_INTERVAL = 500
SS_SIP_NAT_KEEP_ALIVE_SEND_ONE_TIME = 3000

This means:
- Send "HELLO" to each device every 30 seconds
- Wait 500ms between sending to different devices
- Process 3000 devices in each batch

Scaling Notes:
- 3000 devices ร— 500ms = 25 minutes to process all
- Adjust SEND_ONE_TIME for large deployments
- Increase SEND_INTERVAL if network is slow

๐Ÿ” Authentication Parameters

Authentication parameters control how VOS3000 handles SIP authentication challenges and account lockout policies for security.

๐Ÿ“Š Authentication Security Parameters

ParameterDefaultPurpose
SS_AUTHENTICATION_MAX_RETRY6Max auth retries before suspension (0-999)
SS_AUTHENTICATION_FAILED_SUSPEND180Suspension duration in seconds (60-3600)
SS_SIP_AUTHENTICATION_CODEUnauthorized(401)SIP response code for auth challenge
SS_SIP_AUTHENTICATION_TIMEOUT10Timeout for SIP authentication in seconds
SS_SIP_AUTHENTICATION_RETRY6SIP auth retry count for 401/407 responses

โš™๏ธ Authentication Lockout Configuration

Security Configuration Example:

For High-Security Environments:
SS_AUTHENTICATION_MAX_RETRY = 3
SS_AUTHENTICATION_FAILED_SUSPEND = 300

For Standard Environments:
SS_AUTHENTICATION_MAX_RETRY = 6
SS_AUTHENTICATION_FAILED_SUSPEND = 180

For Relaxed Environments (trusted networks only):
SS_AUTHENTICATION_MAX_RETRY = 10
SS_AUTHENTICATION_FAILED_SUSPEND = 60

How Lockout Works:
1. Device attempts registration with wrong password
2. VOS3000 returns 401 Unauthorized
3. Device retries (up to SS_AUTHENTICATION_MAX_RETRY times)
4. After max retries, IP is added to temporary block list
5. Block lasts for SS_AUTHENTICATION_FAILED_SUSPEND seconds
6. After timeout, device can retry

This protects against:
- Brute force password attacks
- SIP flood attacks
- Credential guessing
- Automated hacking tools

๐Ÿ“Š Session Timer Configuration (VOS3000 Media Proxy)

Session timers ensure that hung calls are detected and cleaned up, preventing “ghost calls” and billing errors.

โš™๏ธ Session Timer Parameters

Session Timer Configuration:

SS_SIP_SESSION_TTL = 1800 (30 minutes)
SS_SIP_SESSION_UPDATE_SEGMENT = 300 (5 minutes)
SS_SIP_NO_TIMER_REINVITE_INTERVAL = 7200 (2 hours)

How SIP Session Timer Works:
1. During call setup, session timer is negotiated
2. VOS3000 sends UPDATE or re-INVITE at interval
3. If no response, session is considered dead
4. Call is terminated and CDR is generated

For Non-Timer-Capable Clients:
- SS_SIP_NO_TIMER_REINVITE_INTERVAL sets max call time
- After this duration, call is terminated
- Prevents ultra-long "zombie" calls

โ“ Frequently Asked Questions

Should I set media proxy to On or Auto?

Auto mode is recommended for most deployments. It intelligently enables media proxy only when needed (NAT traversal, encryption, cross-network calls) while allowing direct RTP when possible. This provides the best balance of reliability and server resource usage.

How do I know if my RTP port range is sufficient?

Calculate: Each concurrent call uses 2 RTP ports. With default range 10000-39999 (30,000 ports), you can support 15,000 concurrent calls. Monitor port usage through system performance monitoring. If you see port allocation errors, increase the range or reduce concurrent call load.

Why do calls drop at 30 seconds?

This typically indicates SIP session timer or NAT binding issues. Check SS_SIP_SESSION_TTL and ensure NAT keep-alive is configured. The 30-second timeout often corresponds to NAT binding expiry when keep-alives are not working.

What is the best authentication retry setting?

For most environments, the default of 6 retries with 180-second suspension works well. For high-security environments, reduce to 3 retries with longer suspension (300+ seconds). Balance security against false positives from legitimate users mistyping passwords.

How do I troubleshoot media proxy issues?

Use Debug Trace in VOS3000 to capture SIP and SDP messages. Check if media proxy is being invoked (look at the c= line in SDP). Verify that RTP ports are within configured range. Check firewall rules allow both signaling and RTP ports.
