can anyone tell me how Codec negotiation works? Specifically what ports it works on?<div><br></div><div>I have telecommuters using IPC 7.0.5 connecting with anyconnect (2.5) connecting to an ASA at the head end. Calls to inside 7961's work fine.</div>
<div><br></div><div>but I also have 881's doing site to site VPN with 7961 hanging off the back coming into the same ASA. That phone can call internal 7961 also.</div><div><br></div><div>The problem comes from IPC telecommuters calling 7961's behind the 881's. When you place the call, it rings, they answer, the timer increments up. But with a ?? it does not show a Codec. It looks like we never negotiate the Codec.</div>
<div><br></div><div>is this a Version problem? CM is 7.1.5 and ASA is 8.4.2. I THINK it worked with ASA version 8.2.4 (but I Can't downgrade to double check).</div><div><br></div><div>Any other ideas?</div><div><br>
</div><div>I have a TAC case with the ASA team and they are like ya, the vpn connections work.... open a new ticket with the voice team. And before I did so, I figured you guys are really smart and probably have deal with these kinds of issues.</div>
