Is the Bridge dialplan op (and AMI op):
a) simply a bridging/connection of the media (which I would take as the strict definition) or
b) effectively a transferring together of two channels/calls; in such a way that termination of one channel will terminate the other
Say I use the AMI to originate two SIP calls from a dummy extension. When both calls have connected the channels are bridged. If one channel is then sent Hangup, what happens to the other? Is it dependent or independent. Will the other channel get a hangup event or can I continue to use it and bridge it to other channels?
