I'm trying to setup VoIP calling to/from my Android phone.
I'm currently working on the incoming call part of the equation. To try to isolate the various parts, I started with the "IPKall => Sip2Sip" part of the equation, and confirmed that calling the IPKall phone number results in a recorded incoming call on Sip2Sip.
I then added "Sip2Sip" as a SIP provider on my Android phone, and found that dialing the IPKall number results in the Android phone ringing.
However, and this is where I need help, even though it is ringing, when I go to answer the call, I am unable to pick up the call. Any ideas on how to fix this?
Version of Android is 2.3 Gingerbread.
