<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">The notify subsystem relies on a NOTIFY 200OK response to come back to clear the SIP_PAGE2_STATECHANGEQUEUE flag and p->pendinginvite.
If the response never arrives, then any future NOTIFYs cannot EVER be sent, they just 'queue' up by replacing the previous queued notify.
The fix: Follow RFC6665 4.2.2 more closely, after failed NOTIFY transaction remove the subscription.
Then after a period of time the client will (re-)subscribe, which will create a new subscription.
For minimum BLF 'not working' time maxexpiry in sip.conf needs to be around 300, not the default of 3600 seconds.

Asterisk 1.8 will NOT update it's status when the client re-subscribes, but will on the next event.
Asterisk 11, WILL update it's status when the client re-subscribes.
