Hi Mates,
We have an avaya aura setup, the issue is as follow.
When making a unattendant tranfer to an external number, we randomly have one way audio.When i trace the call, i see that after the transfer is completed, we still be part of the call path and the rtp is still going through our sbc back to original caller.
Any insighits?
 
Check your rtp udp port range between your carrier to the SBC to make sure they match. Then do the same with your inside leg.
