Tail Echo

I have a site where the users are getting echo at the end of sentences from the talker. Incoming calls are going through a VG200 gateway and the listener is using an IP Phone. At the end of sentences the listener gets an echo from the talker.

Re: Tail Echo

Going by your explanation, I understand that you are facing a hybrid impedance mismatch echo problem. As you have this problem only at the end of the sentence, I only suspect that the default echo-cancel coverage value of 8 ms is not sufficient in your network. Try increasing this value to 16ms.
