Hi All
I've a VOIP application and also a GSM (SIM card) in my device. At the time of making call it will show me two options one is VOIP call another one is GSM call. How can i active this two options I mean If i select the option VOIP call then call will be made from VOIP application of my device and if it is selected GSM call then call will be made from GSM(SIM Card) . How can i do that?
