No audio on AVAYA 96 series phones

[smartedge1]

We connected a customer IP office directly on public IP address and we ensured that all default passwords are changed and the sip port is changed from 5060 for security reasons .The customer has power user release 11 licenses and AVAYA IX work spaces works fine . We also have some 9600 series phones connected on the WAN via this public IP address but the issue now it that when a softphone calls the 9600 series there is audio but when the 9600 series phones calls the softphones there is no audio . Can you advise what might be causing this ?.

So what you're saying is that the IP Office has a public IP as it's IP on the LAN interface?

If so, please remove and redo properly.

Thanks for your input . I think that is where the mistake is coming from . The public IP address should be on the WAN interface not LAN . I will make the changes and revert back .

no i think his point is that the public IP should never be on any interface. there should be a firewall or SBC there..

First the phone system should never be connected directly to the internet. Not unless you like being hacked.
For the audio issue have you tried unchecked the box on the "extension-voip" tab labeled "Allow Direct Media Path".

If your not going to it right don't bother doing it at all!
