Hi, I have a networking issue thats bugging me. I have an ethernet circuit on a cisco router provided from the SIP provider (Gamma)that has one interface with a public ip address for internet. And a second interface that is a local address for sip. I have the sip working and authenticating fine. The SIP provider gave me a CPE address for authentication which i have used as my public address in 830 and 831. The problem i have is remote phones connecting through the WAN connection. They connect fine and the outside caller can hear the internal caller, but my media traffic must be going out via the SIP channels as I cannot hear anything. Ive tried putting the second WAN IP address as the second public adddress in 830 and 831 but it doesn't work. Any ideas. How can i route SIP trunks one way and Remote handsets another way? I can send over a network diagram if someone would like to see the network diagram.

Public IP set in "System IP Options"?? You can define different Public IP for SIP trunk as for IP Phone.

Actually I have a simmilar problem, that I didn't manage to solve it yet:
OS7400 v4.8: I have many IP phones on local network )192.168.0.x and some IP phones on remote location connected over VPN: 172.31.1.x
Everything works fine if the pbx is set as "Private only"
But now I need to provide SIP clients and WE VoIP clients to work from public network (over Internet). If I want this, I have to set the PBX as Private with Public, but as soon as I do this I get one way speech on VPN location IP phones.
Entering local IP PBX addres as Public IP 2 for IP phones does not work...
Any suggestions?

I had this problem as well the other day i though I fix it but a hand full of phones still had one way speech about 5 phones from about 250 phones any one have an idea why?
Also none of the phone were on a VPN, All phones are on the same network.

Are they all on the same network as in the same building? Different buildings all tied together by one WAN making it look like same network? Are all of the switches just passing out the same router information or are they giving out different ip information?

Yeah looking closer I could see the phones that had the problem were on a different range to added it to the private IP list and sorted..
