Jonathan, 

I was able to test this in Asterisk 12.0.0-beta1.

Parking works fine, but when parking lot is full, Asterisk sends SIP BYE to both parker and parkee (transferer, transferee) and the call is hung up. Compared to 18.23, Asterisk is left in a stable state though (in 1.8.23, I guess because the parking fails after the channels are masqueraded, Asterisk and phones turn unstable)

Test scenario:
123 called 125. 125 tried to park 123. Parking failed (parking lot is full). Asterisk sent both phones SIP BYE, call is hung up.
