C2DM #999

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
Feature request:

Have you considered adding C2DM (cloud-to-device-messaging) to siproid and 
pbxes.org to replace the TCP standby connection that is currently optimal?

C2DM has been replaced by Google Cloud Messaging (GCM). 

Since sipdroid and pbxes are managed by the same party, there will be no 
security risk with GCM. I bet people will pay premium as battery life is one of 
the major issues with any VoIP solution. In fact, this is a secured service 
that no other sip client can replicate.

Hi all, 
 Can any one just tell me how to combine Google Cloud Messaging (GCM) combined with Sipdroid. i don't have any idea and how to start. and also tell me any performance issue will come for this combination.

You would need to implement the part of SIP that keeps a connection open, 
listening for incoming calls, on the server.  When the notice of a call is 
received, you would send a GCM message to the phone to wait it and have it 
receive the call.

This would save a lot of resources on the phone, but it would add a small delay 
in receiving the call.  And I don't know anything about the internals of SIP so 
I have no idea if this is even possible: having the server do the 'listening' 
but then a different device responds to incoming notice of call.
