Dear sipx list,
I have the following network configuration: Polycom VVX1500 at 10.253.0.16 Sipx 4.0.4-017289 at 10.253.0.51 Vyatta firewall 3.4.7 - Public IP 1.2.3.4 (not really), private IP 10.253.0.254 Gateway RNK at 207.2.123.180 A call is established between the Polycom and an outside line. 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? Here is a highlight of my sipx configuration: Gateway Name: RNK Address: 207.2.123.180 Route: sipXbridge-1 Servers -> server_name IP address: 10.253.0.51 Server Roles: SIP Trunking Conferencing Management Primary SIP Router Voicemail NAT Address type: Specify IP address Public IP address: 1.2.3.4 Public port: 5060 Internet Calling NAT Traversal Enable NAT Traversal: Checked Server behind NAT: Checked Thank you for your help, Brian
