string You can specify the uuid of an originated call using
origination_uuid. This way you can hang up the call before it is answered, since you know the uuid. Just remember you need to use the
create_uuid command to generate the uuid as 2 calls with the same uuid == bad!
Bridge also uses the origination syntax so you can also pre-allocate the UUID for the new channel resulting from a bridge by using the
 syntax and specifying
origination_uuid there, too.
