They are supposed to be the same. The phone does not matter here. Sipxbridge manages that. Your vyaTta router is not doing symmetric nat. ============================ Tony Graziano, Manager Telephone: 434.984.8430 Fax: 434.984.8431

If the vyatta is doing symettic port nat with all ALG or sip filters off, "IT WILL WORK". If I understand you correctly this will only work if the outbound and inbound ports are the same. They currently are not. Here are the contents of the SDP: INVITE from Polycom -> sipx: IP 10.253.0.17 port 2252 INVITE from sipXbridge -> RNK: IP 1.2.3.4 port 30,000 200 OK from RNK -> sipXbridge: IP 207.2.123.181 port 44694 200 OK from sipx: IP 10.253.0.51 port 30,002 Maybe there is some configuration item I'm missing? From: Nathaniel Watkins > How are you liking the VVX1500 - I've been drooling over those for several months now. I don't have much experience with older Polycom phones to compare with.

Voice can be heard from the Polycom on the PSTN phone, but voice from the PSTN phone can not be heard on the Polycom. Vyatta is not creating the NAT rule to route traffic to sipx-bridge. The Polycom sends the INVITE to sipx. Sipx-bridge rewrites the SDP with the public IP address of Vyatta and some new port number, and then forwards the request to RNK. I contacted Vyatta support and they said sipx should not be rewriting the SDP, but instead should leave the private IP address in it. Then Vyatta will rewrite the SDP and open the appropriate port. I can not figure out how to do that. Can you please help?
