No Audio on 9611

[JetKC]

I have a issue with no audio on remote IP phones and confirmed with IT person RTP ports opened. They use a Dell sonic wall and he said ports are opened. As usual, customer thinks Avaya system is bad.... New IT guy too

Are the correct rtp ports opened?

In monitor, you should be able to see what rtp ports are attempting to be used. Have you done a monitor trace of a call?

I would do this:

Pause monitor.
Clear Screen.
Unpause.
Immediately make and connect call.
Talk for one or two seconds with no speech transmission.
hang up.
Pause trace.
Read trace.
Find answer or eliminate issues.


Holdmusic34 is extremely agitated, berating customers, very unpleasant and only calling customers to justify his existence. Signed, a customer.

Eventually the RTP ports are forwarded but not the NAT-RTP ports?

H323 Transformations on the sonicwall?
Direct Media Path turned on on the extensions?

Both can cause no speech on remote IP handsets.
