[OpenSIPS-Users] Pn-uri - Push Notification with SIP

[Răzvan Crainea]

Hi, Jonathan!

To be honest, I haven't fully implemented a push notification solution 
myself, but I've seen some deployments doing it. Basically, when a 
client registers, you need to store the PRID in a database, and when a 
call comes to that client, you need to do a REST query to the associated 
PNS provider, with that ID.
The implementation of this service goes hand in hand with Event Based 
Routing[1] we've been talking about for a while - using this mechanism 
you can "delay" a call until the client re-registers, so you can forward 
the call to it.
Hope this is helpful. If anyone has a working example that he has 
successfully deployed, I am also curious about his story :).
