One way audio on local network is ALWAY because of RTP ports forwarding problem. Your customer's router's firewall is blocking voice data to pass through from the server to the phones. Voice from phones to the server is not blocked that is why the other party can hear her fine. You can also verify it by typing 'rtp debug' on the asterisk CLI when a call is progress. You'll see that RTP is sending packets but not receiving them.
All you need is to open RTP ports 10000-20000 on the router for Polycom phones IP addresses range. The TDM card, zapata or zaptel has nothing to do in this scenario. If you need help with port forwarding, let me know. Zeeshan A Zakaria On 6/24/07, Jason Backshall <[EMAIL PROTECTED]> wrote:

Have heard of issues similar to this - and whilst disabling callprogress may make that symptom disappear, it probably shouldn't be seen as a 'solution', as callprogress has it's place (disconnection detection, etc). Don, have any changed been made to your zapata.conf immediately before this issue started occuring?
