YES, that fixed the problem. I did move the whole network to G729 but it was never a codec problem.
I'm not running CVS, it's 1.0.3 at the moment.
Thanks Scott H

Are you using CVS? I would swear it didn't do this to me in earlier tests, but it is doing it now. I will try to track down the specific change tonight ...
My solution for now is to Answer() the call before dialing out. I changed all of my outbound dialing rules from:
Same problem encountered here. My solution is to answer and play a sec of silence before the dial proceeds - if i don't answer both parties are connected but can't hear each other.

[trunklocal] exten => _9NXXXXXX,1,Dial(${TRUNK}/${EXTEN:${TRUNKMSD}})
To:
[trunklocal] exten => _9NXXXXXX,1,Answer exten => _9NXXXXXX,n,Dial(${TRUNK}/${EXTEN:${TRUNKMSD}})
This seems to fix it, and I haven't identified any side effects. I need to do this anyway to workaround an early-media problem I have.
Does it work for you after this change?

Polycom IP500 Forward problem codec issue
All, I’m running the Polycom IP500 phones at several sites. My * server is at a collocation site and I have complete control of the T1’s running to the remote sites with the IP500 phones. Connectivity to the PSTN is through a Cisco 2600 with a PRI card. During initial testing I ran G711/ulaw but have added G729 licenses to the system.
Problem: When the forwarding function on the Polycom phones is enabled the forward/transfer does work but the caller does not hear any ringing. During the time that the caller should hear ringing the * console produces pages of errors. <snip> ….. Apr 30 08:41:03 NOTICE[2813]: channel.c:1314 ast_read: Dropping incompatible voice frame on Local/[EMAIL PROTECTED],2 of format g729 since our native format has changed to ulaw Apr 30 08:41:03 NOTICE[2813]: channel.c:1314 ast_read: Dropping incompatible voice frame on Local/[EMAIL PROTECTED],2 of format g729 since our native format has changed to ulaw ….. </snip>
I have tested this with the phones behind a PIX firewall with NAT, behind a PIX firewall without NAT, and without a firewall at all. Nat is not the problem.
In the SIP.conf canreinvite=no so all traffic should be passing through the * server.
The problem seems to be in the translation of the G729 packets from the phone to the G711 packets to the router. Only during the forwarding process is this a problem.
Here is a snip from the console when it worked. (Note: it worked because I was ringing two phones with this line in my extensions.conf (exten => ------6081,1,Dial(SIP/------6081&SIP/------6091,20)

Now here is the console output with a single phone defined in the extensions.conf (exten => ------6081,1,Dial(SIP/------6091,20)

I’m sure I could change everything to ulaw G711 the problem would go away but I do not want to do that.
Any Ideas?
Thanks Scott H
