Richard Mudgett e23ea9568c Add dummy call reference support. 
Fixes problem where PTMP NT mode responds erroneously to a FACILITY
message from a phone on the dummy call reference.  LibPRI behaved as if
the dummy call reference were an invalid call reference and proceeded to
respond on the global call reference.
