Review request for Asterisk Developers, Matt Jordan and Mark Michelson.


Changes
-------

The old patch blocked the PJSIP monitor thread which is... horrible. This new 
one doesn't.


Repository: Asterisk


Description
-------

If a PJSIP endpoint attempts to blind transfer to a parking extension, there is 
an override to the normal transfer logic that can make things act a little 
weird. We noticed that this would leave various phones hanging on transfer 
screens without progressing. When the transfer was considered successful, PJSIP 
deferred the actual action of sending the 200 notify and the actual trigger for 
that happening never occurs when the transfer is to a parking extension.

In order to handle this, the bridge function that handles blind transfers now 
returns a different value if a call was parked and if the channel driver needs 
to react differently in this case, it can.  In the case of PJSIP, we respond to 
transfers to park by immediately sending the notify with 200 OK sip frag 
instead of deferring the action.

Testing
-------

Before patch:
* Blind transfer on Polycom SPIP: Phone is on the blind transfer screen until 
it either manually hangs up or 60 seconds pass and Asterisk terminates the 
session.

After the patch:
* Blind transfer on Polycom SPIP: Phone immediately leaves the blind transfer 
screen and goes back to idle mode.


Thanks,

Jonathan Rose
