❓ Frequently Asked Questions

What is the difference between static and registration gateway types?

Static gateways use a fixed IP address configured in VOS3000, and no SIP REGISTER is required. Registration gateways send SIP REGISTER messages to VOS3000 with credentials, supporting dynamic IP addresses and NAT traversal. Static is best for dedicated hardware with fixed IPs, while registration suits remote gateways and devices behind NAT.

How do I enable debug tracing for registration issues?

Navigate to Online routing gateway or Online mapping gateway, right-click the specific gateway, and select “Register tracing” to enable. This captures SIP registration messages without affecting the system-wide debug trace settings. You can set duration for the trace capture period.

What authentication method should I use for vendor SIP trunks?

For vendor SIP trunks over public internet, use Password Authentication Required for highest security. This requires the gateway to authenticate with username/password via SIP digest authentication. For trusted private networks, IP authentication may be sufficient.

Why does my gateway keep losing registration?

Common causes include NAT binding timeouts, firewall blocking keepalive messages, or registration expiry being too short. Configure NAT keepalive settings (SS_SIP_NAT_KEEP_ALIVE_PERIOD), ensure firewall allows SIP traffic, and verify registration expiry times match between gateway and VOS3000.

Can multiple devices register with the same gateway ID?

Yes, but each registration will update the registered IP address. The last registration received will be the active one. For load balancing or failover, consider using multiple gateway configurations with different Device IDs.
