Correct, the variable has been set.

No, and I assumed this to be normal?  When one sip client places a
call to a second sip client on the same Freeswitch, I wouldn't expect
the second sip client to provide some sort of ringing.  In fact,
shouldn't this ringing be happening while the B-leg is being
contacted?  I don't see how it could be the one providing the sound.
In the example dialplan Freeswitch does provide this ringback, but in
doing so it also negotiates a codec.  Hence I removed the ringback,
and suddenly my inherit_codec is providing the functionality expected
minus the ring.
