We’re trying to activate AMD in a call centre that uses g729 codecs.
We have taken the configuration like for like from a working customer setup in the UK who does not have g729 codecs (alaw or gsm is used). Both centres use VoIP, the only other difference is one is in Canada and the other is in the UK.
Every time a call comes through the answer machine detection fails to correctly mark the call. It doesn’t connect any calls through to the agents and it is causing a problem.
Are there any differences with the g729 codecs and AMD on Asterisk? I spoke to somebody who said that it might need to be transcoded for AMD?
On all centres we use Asterisk 1.4.36.
Thanks in advance!
