Unmute on Intercom


Hi All,
Using FreePBX, I’m trying to do a call from a GXP 2160 to a GXP 1450 and have it intercom.

The voice to speaker is working, however, we want duplex (2-way) intercom and the 1450 with the latest firmware doesn’t seem to have a P-code for unmuting on intercom. We would like our users to be able to respond immediately on the intercom.

I saw another thread about using a PBX specific call-info code for HandsFree something, but I can’t recall where I read it or where I would need to put it to work with the *80 feature code.

Any ideas?
