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.
Thanks,

Which end experience the echo? The phone with the loud volume, or the
other end? If it is the remote end that experience echo then I would
suspect acoustic coupling from the earpiece to the microphone inside the
handset.
If this is the case there are a few solutions:
- lower the volume (duh!)
- try connecting another handset with a known good decoupling of the
mic/speaker
- get grandstream to use the software echo canceller when using the
handset as well as when on the speaker phone.
