<div>It does appear to be the remote party that is hearing the echo as a result of the loud volume on the other end. They actually had a few people calling in from the outside report that they could hear their echo. When they turned down the volume on the Grandstream, the echo seemed to go away. So I will bring up the possibility of using the AEC when using the handset.
