Transfer Complete

This event is sent to the transferCompleteUrl of the A-leg's <Transfer> verb when the transferred call (B-leg) completes. In a simultaneous ringing scenario, only one B-leg succeeds and this event corresponds to that successful leg. If none of the calls were answered, the transferComplete event corresponds to one of the legs.

The cause for a transferComplete event on a call can be:

hangup: one party hung up the call, a <Hangup> verb was executed, or there was no more BXML to execute; it indicates that the call ended normally.
busy: the callee was busy.
timeout: the call wasn't answered before the callTimeout was reached.
cancel: the call was cancelled by its originator while it was ringing.
rejected: the call was rejected by the callee.
callback-error: a BXML callback couldn't be delivered to your callback server.
invalid-bxml: invalid BXML was returned in response to a callback.
application-error: an unsupported action was tried on the call, e.g. trying to play a .ogg audio.
account-limit: the account rate limits were reached.
node-capacity-exceeded: the system maximum capacity was reached.
error: some error not described in any of the other causes happened on the call.
unknown: some unknown error happened on the call.
