Disable VAD on Cisco IP Phone

Hi all,

I have implemented ITS with cisco IP phone, but the quality is very poor. I always get the clipped voice...is it something to do with VAD ? How to disable on IP Phone or on ITS router ?

thanks for your feedback

Santo,

There is no setting on the IP phone itself.

In addition to Allan's comments, ensure you disable VAD within call manager....service, service params, server select, call manager service - silencesupression (either system wide or with h.323 gateways).
