I have the GSWave app installed on my mobile, which is registered with the SIP account of my home phone.
That all works fine except when I connect my mobile to the car (over bluetooth). I can still make and receive calls to all numbers - except my home phone number. In this case I am calling from my native mobile dialler (using my mobile number) and calling to my home SIP phone (where I have that number registered in the GSWave app on my mobile). The call still goes through but the audio is diverted to my mobile instead of being played over the car phone. Any ideas of how to prevent this from happening? It means that I can’t call home while driving.
