Caller A calls an Asterisk instance B (where something like a “voicebot” happens) and might get transferred to a Callee C.
Bridging (via the Dial command) the leg of A->B and B->C works but it keeps the call in Asterisk on B. Deflecting the call to C before answering at B works via command transfer.
Since there is a voicebot application at B the call from A needs to answered of course.
Is there a way for the asterisk on B to leave the call after A and C are connected (or bridged) before they end their call?
I read about the unattended transfer DTMF patterns, to be set in the features.conf. But I’m looking for a transfer which is part of the dial plan and not something a user would do.
