Linphone Kolmisoft integration

I have the source code for Linphone which is configured for A2Billing.

I need to configure the Linphone to connect from A2billing to Kolmisoft.

Or if you have a better softphone solution for Kolmisoft, then lets talk about it.

I need to be able to:
-Signup via the softphone (Using SMS)
-Log in
-Make calls
-Topup
-Wake from sleep
