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

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}

Hi Alex, Can anyone provide advice on how to determine first registration of a phone coming back online in another way? 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?

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