SIP registration is the process by which endpoints (phones, gateways, softphones) establish their presence with VOS3000. During registration, the endpoint authenticates itself and provides its current contact address, allowing VOS3000 to route incoming calls to the correct destination.

| Error Type | Symptom | Common Causes | Solution |
|---|---|---|---|
| 401 Unauthorized | Auth challenge fails | Wrong username/password | Verify credentials in gateway config |
| 403 Forbidden | Registration rejected | Account locked/disabled, IP not allowed | Check account status, verify IP in gateway |
| Timeout | No response from server | Firewall blocking, wrong server IP/port | Check firewall rules, verify server address |
| 503 Service Unavailable | Server temporarily unavailable | Server overload, service down | Check server status, restart services |
| Dynamic Blacklist | Blocked after failed attempts | Multiple failed auth attempts | Remove from blacklist, correct credentials |
VOS3000 provides a built-in Registration Analysis tool that helps monitor and troubleshoot registration issues. This tool shows registration status, failures, and patterns that help identify problems.
| Feature | Location in GUI | Purpose |

Dynamic blacklist in VOS3000 enables automated threat response by blocking attack sources in real-time without manual intervention. Understanding this feature is essential when troubleshooting registration failures, as legitimate devices can be blocked by mistake.
| Trigger Type | Condition | Default Action | Resolution |
|---|---|---|---|
| 🔓 Failed Authentication | 5 failures in 10 minutes | Block IP temporarily | Wait timeout or remove manually |
| 📞 Suspicious Calling | High volume from single source | Rate limit or block | Verify legitimate traffic |
| ⚔️ Attack Detection | SIP flood or brute force | Permanent block | Manual review required |
| 📊 Anomaly Detection | Unusual traffic patterns | Alert or temporary block | Review and whitelist if legit |
To manage the dynamic blacklist in VOS3000:
Correct port configuration is essential for successful SIP registration. VOS3000 uses specific ports for SIP signaling, and understanding these helps troubleshoot firewall and connectivity issues.
| Port | Protocol | Purpose | Firewall Rule |
|---|---|---|---|
| 5060 | UDP/TCP | Primary SIP signaling (unencrypted) | Allow from trusted IPs |
| 5061 | TLS | SIPS signaling (encrypted) | Allow for TLS connections |
| 5070 | UDP/TCP | Additional SIP port | Allow if configured |
| 8080 | TCP | Web management interface | Allow admin access |
| 10000-20000 | UDP | RTP media ports | Allow for voice traffic |
VOS3000 supports adding additional SIP registration ports for flexible deployment:
Use cases for multiple SIP ports include separating traffic by customer, dedicated registration paths for specific applications, and supporting endpoints behind restrictive firewalls.
VOS3000 supports two primary authentication methods for mapping gateways and endpoints. Choosing the correct method affects both security and troubleshooting approach.
| Method | How It Works | Security Level | Best For |
|---|---|---|---|
| IP-Based | Only source IP is verified | Lower (IP spoofing risk) | Fixed gateways, trusted networks |
| SIP Digest | Username/password challenge | Higher (credential required) | Softphones, mobile apps, any IP |
| Both | IP + credentials required | Highest | High-security environments |
Step 1: Check Network Connectivity
├── Can you ping the VOS3000 server?
├── Is the SIP port (5060/5061) reachable?
└── Test: telnet server_ip 5060
Step 2: Verify Credentials
├── Check username in gateway config
├── Check password matches exactly
└── Verify rate group assignment
Step 3: Check Account Status
├── Is account active (not locked)?
├── Is agent account active?
└── Is balance sufficient?
Step 4: Check Dynamic Blacklist
├── Is the IP in dynamic blacklist?
├── What triggered the block?
└── Remove if false positive
Step 5: Verify Gateway Configuration
├── Is IP address configured correctly?
├── Is auth method correct?
└── Are SIP ports matching?
Step 6: Check Server Status
├── Are VOS3000 services running?
├── Check Process Monitor
└── Review system logs
Common causes include registration expiration (check registration interval on device), NAT issues (configure NAT keepalive), firewall blocking SIP traffic, or server-side session timeout. Verify device registration timer matches server expectations.
Navigate to Number Management > Dynamic Black List in the VOS3000 GUI Client. Search for the IP address to see if it is blocked and view the reason and timestamp of blocking.
Mapping gateways are typically configured for origination (receiving calls from customers) and may use IP authentication. Phones are end-user devices that typically use SIP digest authentication and register for receiving calls.
The dynamic blacklist threshold can be adjusted in system parameters. Navigate to System Management > System Parameter and adjust the failed authentication threshold settings. Balance security against false positives.
