<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;">Follow RFC6665, 4.2.2
Now remove subscription after the retries fail.
This now relies on the client to re-subscribe in a timely manner.
Ideally maxexpiry in sip.conf needs to be small, like 300, instead of the default of 3600 seconds.
This way, the BLF will not be wrong for too long. But that's a user setting.
Testing:
Make check that subscriptions are removed.
With Asterisk-11, also that when the device re-subscribes that the BLF is then correct, as immediate State Notification is now after each (re-)subscribe.</pre>

<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 sub system 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: assume after a period of time (2 seconds), if we haven't had a response, that the request/response got lost.
