Hi all, I've been messing around with the g729 codec in some phones I use and had made all phones use the codec for all calls for testing purposes. The problem is when I attempt to dial out on my Polycom IP 500 (test happens to be calling my cell phone) I can only hear sound coming one way, I recieve nothing from one user, just silence, yet I can talk one way perfectly. Now I tried the same call (forced g729) on my Cisco 7960 and had no problem connecting the call and having conversation heard both ways. I originally thought perhaps since I had only purchased one g729 channel license that it may cause such a problem, but then why does my 7960 connect with g729? I also had some problems with a SNOM 220 I had tried out as the audio was non-existant on both ends if I remember correctly, but I havent tried that one in a while so I may be incorrect. My primary concern is the Polycom anyway. I even had a buddy couble check through the gateway I am using that both calls went through as g729 and were connected (which obviously they were if any audio was heard). Is there something I am missing in the config on the Polycom 500? I am 99% sure the firmware is up-to-date... Thanks for any help, Matt -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20050619/5433994b/attachment.htm
It looks like a NAT issue.

What DTMF mode are you using? -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20050620/87f11541/attachment.htm
I have rfc2833 listed as my dtmfmode in sip.conf... sorry if this wasn't what you meant - I'm pretty new to this stuff. Just let me know if you meant to look/ask somewhere else for that On Mon, 20 Jun 2005 13:04:12 -0400, "Bryan M.

Another odd thing I noticed was I will dial my cell phone, I will pick up and just for that half a second right after i pick up the phone I can hear audio both ways...it then cuts out and only audio is heard talking to the poly and heard on the cell but not the other way around. I was unsure if this may perhaps reveal any more on the problem...and again this only occurs when forcing it to use the g729 codec Matt On Mon, 20 Jun 2005 13:04:12 -0400, "Bryan M.
