Hi, I suspect that you are "transcoding", meaning that the call is comming in a specific codec format, and the second phone uses another codec. So, when you do your tranfert, Asterisk is in the middle and is coding from the original to your phone with two different codecs. If you are passing from G711 to GSM, for example, it's normal that the audio quality is worst.

In the direct call, the quality of the voice and dtmf are acceptable. After transfer, the quality becomes worst. Voice can't be heard clearly and dtmf wrong detection will occur sometime. I wonder call transfer will affect he quality of the call. Anyone has same experience? Anything to do in asterisk level can get a better quality after call transfer? _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
