Well, the call is still in PJSIP_INV_STATE_CALLING and I want to play
the ringback.
Thanks to your suggestion I added a check like this:

    pjsua_player_id player_id;

    pj_status_t status = pjsua_player_create(filenameP, 0, &player_id);
    if (status != PJ_SUCCESS) {
        NSLog(@"Failed to create player");
        return;
    }

    pjsua_conf_port_id src = pjsua_player_get_conf_port(player_id);

    if (src != PJSUA_INVALID_ID) {
        NSLog(@"src port invalid");
        return;
    }

    pjsua_conf_port_id dst = pjsua_call_get_conf_port(call_id);

    if (dst != PJSUA_INVALID_ID) {
        NSLog(@"dst port invalid");
        return;
    }

...and it turns out the src port (pjsua_player_get_conf_port) is invalid.
I just created that one?!
Any further pointers?

cheers
