Problem: Have a Nortel BCM 50 with a DMC unit with 4 handsets. When you make or receive a call on the wireless handsets there is no speech path when you go off hook. Tested the ports on the BCM and they test o.k.. Checked programming for the wireless extensions and the only thing I see is that it will not let you assign an intercom key to the wireless phone. I can call other wired phone extensions from the wireless, but no speech path. Not quite sure what else could be wrong. Any suggestions will be appreciated.
