Apple authorizes/allows background task with TCP connection only.
If your SIP provider doesn't allow this kind of connection, you can't enable 
background support.

You are correct, my server is only allowing UDP connections. Don't want to
enable TCP. It is fine then. Stupid Apple! Thank you.

i am not sure about this, i selected TCP and could not connect in siphon, but 
in Bria i could connect just fine with backrounding .. i hit the menu key, 
started fragger and then locked the phone, called my self and Bria brought the 
phone to life.

Did you set Bria to use TCP? I just tried it and it would register with my 
server as it doesnt accept TCP connections.

I did connect with Bria, double clicked the menu key to enable Backgrounder, 
closed Bria, locked the phone and was able to receive a call.

When I tried it with Siphon, I opened Siphon, double click the menu key to 
enable Backgrounder, closed the app but Backgrounder stopped. It said 
Backgrounder enabled but after a few seconds the Backgrounder icon disappears. 

Enabling "Run in Background" on Bria doesnt work, maybe because TCP is not 
being used. If I open Bria, lock the phone, it rings. If I open Bria, close the 
Bria (I assumed backgrounding meant this) it doesnt ring.

Both are using UDP so I dont know what is going on.

no, i didnt enable tcp in bria, every thing is default, so must be UDP since my 
provider dosnt support TCP, which means they some how got background support 
enabled on UDP
