We have iPhone application in appstore. And now we want to add push notification supper to our application.
So we need to add push notification capabilities into our solution. This should work some kind of this:
if user is subscribed to push *service*, then when application(iphone ios app) is backgrounding:
-application sends request to this *service* (via http for example)
-*service* registering with sip-server( based on sip-credentials, that user defined in his settings in application)
-when incoming call arrives - *service* sends push to wakeup the phone
-after waking up phone connects to OUR sip server and *service* connect him to existent call
I think it could be done via perl Net-SIP.
