[Freeswitch-users] no hang-up on B leg

[Michael Jerris]

src/switch_ivr_bridge.c

This could just as well be a glare condition when the call is in process of tearing down.

On a number of occasions I get an error saying the B leg doesn’t exist, so I now do a double kill on the associated leg which I get from the event.  I do not get a ‘doesn’t exist’ message for the A leg, which leads me to believe that process of tearing down both bridged legs is flawed.
