Hello,
I think there maybe an issue with my refer transfers. See below or attached:

As you can see Asterisk excepts the REFER, Status: 202 Accepted is returned.
However believe the NOTIFY is incorrect. If I
understand RFC 3515 correctly, the NOTIFIY should respone with 100 Trying, not
200 OK. See http://rfc.arogo.net/rfc3515.html section
4.1 Prototypical REFER callflow.
Am I correct, or out in left field?
