Based on the test coverage for this[1] you aren't really expected to
manipulate the bridge yourself. The ";1" side of the Local channel is
supposed to automatically go into your ARI application and take the
transferer channel place in the bridge, and then the transferer leaves the
bridge and ARI application. I don't know why both channels are going
through the dialplan in your scenario.
