Review request for Asterisk Developers and Russell Bryant.


Summary (updated)
-------

Issue 17999
1) A calls B. B answers.
2) B using DTMF dial *2 (code in features.conf for attended transfer).
3) A hears MOH. B dial number C
4) C ringing. A hears MOH.
5) B hangup. A still hears MOH. C ringing.
5) A hangup. C still ringing until "atxfernoanswertimeout" expires.

Problem: When A and B hangup C is still ringing.

Issue 18395
SIP call limit of B is 1
1. A call B, B answered
2. B *2(atxfer) call C, C ringing (no answer)
3. B hangup
4. C cancel call
5. Call to B fails because B has reached its call limit.

Because B reached its call limit, it cannot do anything until the transfer it started completes.

Issue 17273
Same scenario as issue 18395 but party B is an FXS port.
Party B cannot do anything until the transfer it started completes.  If B goes back off hook before C answers, B hears ringback instead of the expected dialtone.


This addresses bugs 17273, 17999 and 18395.
