<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This should be documented more since it's now a wrapper. Are there any expectations? Should it be allocated in any specific way? In the case of res_pjsip_refer it expects this as an AO2 object, but that's currently an implementation detail of the blind transfer/parking code that is not documented. Could your stack usage of this be passed into the announcement tracker and hilarity ensue?</pre>

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.</pre>

* 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.</pre>
