7921 - no outbound audio for pots calls

I also posted this in IP Telephony. Not sure which section is more appropriate for my problem, but I really need help here.

 

I have an odd problem.

I have a 7921, which registers as it should in an CUCME 8.6 environment.

4 ephones, (3) 7975G and (1) 7921. One incoming / outgoing pots line. No voip.

 

My problem:

calls made from the 7921 to internal extensions work perfectly. Audio in both directions.

Calls made from the 7975's to internal extensions and to external numbers via pots (VIC2-2FXO) work perfectly - audio in both directions.

Calls made from the 7921 to external numbers via pots, however, have no outgoing audio. Inbound audio works fine.

 

Any ideas? Config is attached
