<tt>Hi, Jonathan!<br>
<br>
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.<br>
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.<br>
Hope this is helpful. If anyone has a working example that he has
successfully deployed, I am also curious about his story :).<br>

<div>We use opensips in the core of our network and are looking
to implement Push Notification with the Session Initiation
Protocol (SIP), as per this spec;</div>

<div><span style="font-size: 12pt;">Can anyone recommend a push
server software that can be used in the scenario, that
opensips can integrate with?</span><br>
</div>
<div><br>
</div>
<div>I can see there are plenty of open source options out
there, just wondered if anyone else had implemented?</div>
