Question

I am developing a simple sip-based voip app for android.
I used this sample but there were some problems and I decided to write it step-by-step.

First I want to do registration on server. I do:

SipManager manager = SipManager.newInstance(this);  
SipProfile.Builder builder = new SipProfile.Builder(number, server);
builder.setPassword(password);
SipProfile me = builder.build();

And it works fine. But when I do

manager.register(me, 1000, null); 

or

manager.open(me) 

my app crashed. I test this on Samsung i9000.
I think a problem is somewhere in wifi connection.
Any advices how to fix?

Answer 1

Try to check with SipManager.isApiSupported() and SipManager.isVoipSupported() is SIP is supported on your device. Perhaps Samsung disabled the SIP API.
