I have created an issue report on this a few weeks on with Asterisk
1.6.2.8-rc1. This was happening on a client site, which I didn't have
a chance to stop back by, so they closed the issue.

https://issues.asterisk.org/bug_view_page.php?bug_id=17379

It looked to me like Asterisk was rejecting the NOTIFY message due to
no callid, which is in the message. I couldn't figure out what was
going and there is code in 1.6.2.x to return a 200 OK to a NOTIFY
message.
