Allows one channel to bridge itself to the a or b leg of another call. The remaining leg of the original call gets hungup (or does this only happen with hangup_after_bridge?)
To intercept the b leg of the call:
Via sendmsg on the event socket:
Intercept additional variables
To intercept only if the call is not bridged (available since git-58fe45a):
To intercept only if the call was not answered:
intercept_unbridged_only is useful e.g. in scenarious where the initial call has been answered and transferred and is ringing at the transfered extensions. With intercept_unanswered_only=true this call could no longer be intercepted, but with intercept_unbridged_only=true it still can be.
