Q22. I am using SIP-ALG for VoIP Calls between my branch offices. My VoIP Call has been established, but I am unable to hear the voice of the other person. What could be the problem?

Ans: This problem can occur if the SIP Phone has been registered to the Server with the private IP Address/Port. Ensure that your phone’s signaling port or the SIP Server signaling port has been configured at the router via NAT → SIP-ALG.

Q23. I am not able to make calls after rebooting the router. Why?

Ans: After rebooting, the router cannot remember the device registrations which happened earlier. You have to register your device again after the router reboots.

Q24. Can I use SIP-ALG for Video Over IP?

Ans: Yes. SIP-ALG can be used for both Voice and Video over IP. The only requirement is that the voice/video endpoints or equipment use SIP (Session Initiation Protocol) for Call Establishment and RTP (Real-time Transport Protocol) for Voice/Video traffic.

Q25. Can I use TCP for SIP signaling or media traffic in DRO2xx router?

Ans: DRO2XX routers support only UDP for both signaling and media traffic.
