Ha ha!  As soon as I ask for help, I figured it out.  The answer was here:


"If you would like to handle incoming calls using inbound mode, you should
add the *park* command to your dialplan. Otherwise the dialplan might
complete executing before your client can send commands to the event socket.

Thanks anyway and sorry to bother you.

All the best,
