Actually, from the incoming call log, it looks like the call is 
established properly (call state shows CONFIRMED). So 
congratulations for your first Symbian call!

(In pjsip) UAS invite transaction will be terminated upon receiving 
ACK, so this is normal. Termination of invite transaction after 
200/OK doesn't mean that the call is terminated.
