Nope, not a bug - that's by design. The transmission of the CHANNEL_BRIDGE
event means it was successful. The OK+ from the API call to bridge simply
means that the bridge command was successfully submitted for processing, not
that the processing of it was successful. This is the power, beauty, and
elegance of the event system in FS. Events tell you pretty much *everything*
that is going on and you can pretty much do *anything* when you harness the
power of events.
