Hello,

Customer has Avaya Release 11 Service Pack 1. When Initialising Calls from SIP to H.323, everything is okay.
But once the call is initialised from an H.323 Extension to both H.323 or SIP, there is no audio and dial tone.

Does anyone know what could cause this?

Thanks in advance
 
Further to the previous post,

The Avaya Default RTP Port range is 46750 to 50750, Port number range(NAT) is 54000 to 54500.

Pls does anyone know the RTP Port range that we can use to achieve Dial Tone?
 
sounds like a routing issue between vlans/subnets
to prove swithc off direct media path
if that works you need to correct your network routing tables.



Do things on the cheap & it will cost you dear
 
We already unchecked "Direct media Path" on the extensions.
