Hello, I've created a simple script to play an audio file and redirect it to the operator(CUCM).
It is working fine on PSTN calls, but as soon as the source is a SIP call, then the call will be transfered without audio.
Has the router be configured in a special way to use early-media with sip in a vxml application? Or am I missing something in the vxml script?
Kind Regards
Heimo

Hi Heimo,
from the logs it shows that play audio failed because of codec mismatch, please configure "codec g711ulaw" to your dial-peer 52.

Thank you Raghavendra
the missing codec in the dial-peer was the problem.
