Hello, I have been experiencing audio problems when accessing the Voicemail application using DECT phones and the g729 codec. The issue is that whereas the vm-password is always played correctly by the DECT phone, the rest of audio files, randomly, are played or not by the DECT phone. Everything works correctly if another codec (alaw,ulaw) is used.
I have noticed that asterisk doesn't send RTP with silence, but stop sending them and I think the problems is that the DECT phones are having problems with that. To check that this was the problem I have implemented a simple dialplan exten => *91,1,Set(CHANNEL(language)=es) exten => *91,n,Answer() exten => *91,n,Wait(4) exten => *91,n,Playback(vm-tmpexists) exten => *91,n,Wait(4) exten => *91,n,Playback(vm-tomakecall) exten => *91,n,Wait(4) exten => *91,n,Playback(vm-goodbye) exten => *91,n,Hangup ...and I have verified that if there is a pause between the playbacks the problem occurs, otherwise the audio is played correctly by the DECT phones I know it looks like a problem with the phones but, is there a way to configure asterisk so it sends RTP during silent periods? Thanks. Best regards, Santi
