The channel call this function but it is not hanging up
This code is based on chan_alsa.
Here is the function:

static int usbb2k_hangup(void)
{
	int res = RESULT_SUCCESS;
	stop_sound();
	ast_mutex_lock(&usbb3g_lock);
	if (!chan_yealink.owner /*&& !hookstate*/) {
		res = RESULT_FAILURE;
		usbb2k_setmode(USB_MODE);
		HANGUP_PSTN(chan);
		UNJOIN_PSTN(chan);
		hookstate = 0;
	} else {
		hookstate = 0;
		grab_owner();
		if (chan_yealink.owner) {
			grab_owner();
			ast_queue_hangup(chan_yealink.owner);
			ast_channel_unlock(chan_yealink.owner);
		}
		ast_verbose(VERBOSE_PREFIX_2 "USBB2K USB hangup properly\n");
		usbb2k_setmode(USB_MODE);
		HANGUP_PSTN(chan);
		UNJOIN_PSTN(chan);
	}
	ast_mutex_unlock(&usbb3g_lock);
	return res;
}

Is there another way to do this or is there something wrong with this
function???
