asterisk users - Dec 2005 - SIP Subscription Storage Location

SIP Subscriptions are cached in memory. I'd like to find out if there's
a way to have them cached in a file, say astdb ('ie database show')
rather than in RAM. If your Asterisk process is stopped and restarted, you lose
all the SIP subscriptions. Registrations on the other hand are still in the file
when Asterisk restarts.
 
If you lose your subscriptions, you also lose all your BLF indications. Phones
have to reboot. Yuck!
 
I can't understand why it was implemented this way (lack of design maybe?).
SIP subscriptions have an expiry just like a registration does, so why not put
them in astdb as well? Lots of other things are in astdb. Anyone know if
it's possible?
 
Thanks,
Doug.

Yep, that's it.  Asterisk was designed by a bunch of fools who never 
even gave the first thought to what they were coding up.

Yore kinda quick to knock over the china, pardner.

I guess I'm not fully grasping it because I don't see it as a problem.
So asterisk gets stopped and started. The subscriptions are still there if they
are cached. Why is that a problem?
 
I think we would definitely make ourselves available for testing. What's the
procedure for that? How do we let the powers that be know that we are interested
in this feature, and would happily test it if available?
 
Another problem (probably because the subscriptions aren't keyed on
extension like registrations) is that Asterisk will keep adding new
subscriptions to existing ones. Every time a phone reboots, it sends a new
subscription which Asterisk happily adds to the already growing list.
When that phone makes a call, every phone that is watching it gets a
notification, including all the duplicates. I guess it doesn't seem to be
breaking anything, but it's damn annoying and makes SIP traffic harder to
debug. Throw a few thousand phones on there and you've got a mess.
 
Doug.

	 It's not as easy sip registrations. Should we assume that the phone
	is going be OK and isn't going to get confused if we just pickup and
	start sending state notification that may conflict with where we left
	off when Asterisk exited or sip reloaded?
	
	 I agree with you that this is something we should implement, but it's
	not a trivial matter to do so. Will you make systems and yourself
	available for testing once it is implemented by the dev team?
