    No Voice on Outbound Calls Adtran 712

      My phone system consists of a 7100 with Polycom IP560s and Adtran 712s and 706s.  I am using a SIP trunk for outbound calling.  My Polycom phones work fine but the Adtran phones are having an issue.  When I call out, the call is placed, but the person on the other end cannot hear me.  There is no voice getting out to the SIP trunk.  I know this is probably an easy fix, but I haven't run across it yet.


      Thank you.
