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

I'm going to go ahead and ack the issue, but remember my quote from earlier:

I'm fine accepting this issue on that notion, but without a well written and well tested patch, I doubt this issue will get much traction - particularly when chan_pjsip generally handles this case better already.

> We are experiencing an issue where the SIP channel driver pauses and does not allow further registrations or calls to progress.
> Looking at core dumps shows lock waits for app_dial and presence.
> Unfortunately asterisk had not been compiled with the correct settings so I will need to provide further back traces when the issue happens again, however have attached the files I have now.
