[Asterisk-code-review] chan_pjsip: Incorporate session reference count into transfer_refer(). (asterisk[master])

[Dan Cropp]

Hello Friendly Automation, 

I'd like you to reexamine a change. Please visit

    https://gerrit.asterisk.org/c/asterisk/+/15208

to look at the new patch set (#2).

Change subject: chan_pjsip: Incorporate session reference count into transfer_refer().
......................................................................

chan_pjsip: Incorporate session reference count into transfer_refer().

Add session reference count for PJSIP REFER. The call could be
terminated prior to the result of the transfer. In that scenario,
when the SUBSCRIBE/NOTIFY occurred several minutes later, it would
attempt to access a session which was no longer valid.
