Summary:                    CNG or T.38 invite detected while call is bridged
causes dialplan execution to stop after ReceiveFax
Description: 
We have calls that come in via SIP and are immediately routed out Dahdi PRI
to a voice platform.  The call is answered by the Dial() function before
bridging.  In cases where CNG or T.38 invite is detected after the call is
bridged, the bridge is broken, the hangup extension is executed, and then
the fax extension is executed.  When executing the fax extension, after the
fax is received, ReceiveFax recognizes that the call has hung up and upon
exiting should go to the hangup extension for post-fax processing. 
Instead, the dialplan execution stops and we have no ability to perform fax
reception processing (email fax or process with a script) because the
dialplan never gets executed after the ReceiveFax.
