Re: [OpenSIPS-Users] how do you determine first registration of a device

[Alex G]

the answer to this problem is NO!  there is no sure fire way to do this that
will be 100% foolproof !

so my suggestion is... just give up and make your phones subscribe! They'll
do it when they boot O_O

Why don't you send the NOTIFY to the AOR of the user rather than to the real 
location of it?
Sending the NOTIFY to the AOR it will be received by all the devices 
registered for that AOR.

What you are trying to achieve seems a bit "dirty" to me. There is no way to 
have full control on when a registered user is still "online" or not.

Re: [OpenSIPS-Users] how do you determine first registration of a device

[Bogdan-Andrei Iancu]

Hi Alex,

As said, from SIP point of view, a registrar cannot tell (in a reliable 
way) if a registration is a first registration or a re-registration. 
Simply there is no information to help with this. No hocus-pocus with 
deleting the previous registrations or unregister will not help.

BUT, the only thing you can use is that during a re-registration the 
callid may be preserved (and cseq increased), while during a fast 
reboot, the callid (in REGISTER) will be definitely a new one.

So, as you can see, you can make 100% distinction between the two cases, 
but you can identify a first registration (when a new callid is received 
from the client). So , if it is not a big issue that you may detect 
"supplementary" first-register events (like a re-register when the 
client simply decide to change the callid), you can use in 1.6 the new 
"callid" parameter on the "registered()" param:
  
http://www.opensips.org/html/docs/modules/devel/registrar.html#id271243

like:
   if (registered("location","$to","$ci")) { -> received callid is 
already registered -> not a first registration}

Bogdan

It actually has an unregister() function as well.

Re: [OpenSIPS-Users] how do you determine first registration of a device

[Alex Balashov]

A new REGISTER request will certainly have a different Call-ID.

However, I think the correct way to handle this is to just live with 
it.  If the phone did not "unregister," then it will be subject to the 
consequences of that, and it's okay.

Kamailio 1.5.x's registrar module has a function called 
reg_free_contacts() which you could use if a save() fails due to a 
contact already existing in memory or database and then call save(). 
Perhaps OpenSIPS will implement something like this at some point.

Re: [OpenSIPS-Users] how do you determine first registration of a device

[Alex G]

this still does not solve the issue of a reboot that occurs in under 60
seconds. if a phone does not unregister on reboot, the record remains in the
db for those 60 seconds. if it comes back up in under 60 seconds, then to
opensips it looks like a reregistration.

is there someway to discern this scenario from the info in the location
table that is already there? maybe the callid or cseq or something?

Re: [OpenSIPS-Users] how do you determine first registration of a device

[Alex Balashov]

As Inaki said, what you're trying to achieve is a little ridiculous.

But, if you must do it, I recommend using a database capable of 
advanced triggers and decent stored procedures (PostgreSQL) and using 
usrloc and registrar with full database backing and no caching or 
synchronisation (changes immediately reflected in database).  Then put 
a trigger on your 'location' table.  Trying to do this from the route 
script is silly.

Re: [OpenSIPS-Users] how do you determine first registration of a device

[Alex G]

i have a 60 second expire on my location table, but some phones still will
reboot in less time than that. especially soft phones like xlite. i need to
know when this first registration is in order to trigger a script that send
mwi notification if that device has new messages. none of my devices
subscribe for it, therefore i have to send notifications to them.

Depends on the phone I would say. From my point of view I would say,
that is very hard to track, since some phones acts very strange in that
case. Maybe short expire would help?

Can you tell more about your setup?
