Question

I developing VOIP android application that make and receive the sip call.I Build the pjsip lilbrary as described in " http://trac.pjsip.org/repos/wiki/Getting-Started/Android ".

I use the pjsua sample application code for make sip call by using:

      MyCall call = new MyCall(account, -1);
      prm = new CallOpParam(true);
            try {
                call.makeCall("destination Sip Address", prm);
            } catch (Exception e) {
                call.delete();
                return;
            }

I am able to make Call but not able to receive call.What I do for receive sip call in my application?

Thanks.

Answer 1

Recently I was also testing those code samples on Ubuntu 16.04 LTS virtual machine with PJSIP 2.5.5 and got the same problem. Can make outgoing calls to my Asterisk server on a Raspberry Pi or to other clients (btw quality is not so perfect :/) and NO way to receive incoming calls.

I'm picking up SIP error 603

(from Wikipedia: " 603 Decline The destination does not wish to participate in the call, or cannot do so, and additionally the destination knows there are no alternative destinations (such as a voicemail server) willing to accept the call.")

and info from asterisk console, that user is busy.

Did you come up with something in that case??
