Summary:                    Attended transfer - transfering phone left connected
Description: 
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.

---------------------------------------------------------------------- 
The scenario is very simple.
I've attached the SIP flow with 2 sides (A and B) and 2 connections.
A send Invite to B
B send Invite with replaces (second connection).
A accepts it. But it does not send Bye to the first connection.

According to attended transfer scenario it should.

This issue has been patched very long time ago in
https://issues.asterisk.org/view.php?id=7784
However no changes have been made to SVN.
