ios - pjsua_call_make_call return status 450851 -


i'm working on voip app, when dialling number, 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 restart handler", status);         [siphandlerlistener restart:yes];     } else {         // continue actions     } }

for long time, decoded error message non-successful status "default status message" until when traced status value gave me 450851. searched error code , found:

unable open sound device: core audio error [status=450851]

i saw many people post log message in other places, error , has fix error?

note have no sound problem other situations, e.g. receiving incoming call rings, answering call etc.
