---------------------------------------------

If could be useful, I notice that the problem doesn't appear on version 12.0.0.

> The issue 0015833 still exists in newest version of Asterisk.
> When doing a remote attended transfer in one of these 2 setups:
> phones A,B,C --- proxy --- asterisks Z,X
> when A->B call is on Z and B->C is on X, or:
> phones A,B (with identity B1,B2), C --- asterisks Z,X
> (A,B1 register on Z; B2,C on X)
> when A->B1 call is on Z and B2->C is on X
> In both scenarios Z and X are friends with no authentication needed.
> The B phone doesn't get properly disconnected. asterisks invite/replace each other properly and the audio channel is ok. B itself drops one of the calls. But Z is not disconnecting B's call at all. You can replicate that scenario with minimalistic dialplan - _X.,Dial(SIP/${EXTEN}) in default on both sides.
