SIP Call error: pjmedia_endpt_create_base_sdp: Assertion `!"Invalid address family"' failed

Question

I am a college student who is new to VOIP and SIP. I have a SIP server setup and am able to register myself, but when I try to make a call, there is this error:

10:43:18.461 pjsua_acc.c ..Acc 0: Registration sent 10:43:18.461 pjsua_call.c Making call with acc #0 to sip:[email protected] 10:43:18.461 pjsua_media.c .Call 0: initializing media.. softphone: ../src/pjmedia/endpoint.c:935: pjmedia_endpt_create_base_sdp: Assertion `!"Invalid address family"' failed. Aborted

This is the piece of code that I think is the problem:

// Make a call with audio disabled
    CallOpParam prm(true); // Pass true to indicate this is an outgoing call
    prm.opt.audioCount = 0; // Disable audio

    // Debugging info for call setup
        try {
            MyCall *call = new MyCall(acc);
            call->makeCall("sip:[email protected]", prm);
            cout << "*** Call setup completed ***" << endl;
        } catch (Error &err) {
            cout << "Error during call setup: " << err.info() << endl;
        }

(I have disabled the audio because there were permission errors and no audio device errors)

I noticed that your line

prm.opt.audioCount = 0;

You can try to disable the SDP protocol before sending the INVITE. It might be in a call setting, such as prm.opt.flag = CALL_NO_SDP_OFFER? This requires you to look at what the corresponding variable of the struct is.
