Return Status pjsua_call_make_call 450851

Question

I am working on a VoIP application, when I dial a number, I use:

status = pjsua_call_make_call(acc_id, &pj_uri, 0, NULL,  &msg_data, call_id);
if (status != PJ_SUCCESS) {
        pjsua_perror(THIS__FILE, "Error making call, going to restart handler", status);
        [SipHandlerListener restart:YES];
    } else {
        // continue with actions
    }
}

for a long time, my decrypted error message for an unsuccessful state is “Default Status Message” until I traced the status value that 450851 gave me. Then I looked for the error code and found:

Unable to open sound device: Core audio error [status=450851]

I saw how many people published this message in other places, but what exactly is this error about, and who has a fix for this error?

Please note that I have no problems with sound in other situations, for example. receiving incoming calls, answering a call, etc.
