Hi guys,
Hopefully someone can help us with our issue. We recently purchased a Polycom IP 7000 (UC 4.0.10.0568) and register it to our Avaya Session Manager & Communications Manager. However we can't make an outbound call. Call disconnects at 22 seconds.
On our SIP trace, we can see that 183 Session Progression is being sent to the Polycom but it's not responding a PRACK causing a timeout. We have checked all of the configurations and all looks good. Do you think this is a hardware issue?
Inbound calls work properly though.
Thanks in advance!
