I don't know what exactly happened in your case but if you don't have time
to investigate you can try cnxcc module [1] channel control to achieve the
same goal.

Take a look at the sample configuration file located in [2]

xlog("L_INFO", "Setting up channel based credit control");

	$var(max_chan)	= 2;
	$var(retcode)	= cnxcc_set_max_channels("$var(client)", "$var(max_chan)");

	if ($var(retcode) == -1) {
		xlog("Error setting up credit control");
		return;
	}

        $var(count)     = -1;

        if (!cnxcc_get_channel_count("$var(client)", "$var(count)")) {
                xlog("Error getting customer's channel count");
        }

        xlog("L_INFO", "CNXCC ROUTE: $var(client) has $var(count) call(s)");

	if ($var(retcode) < -1) {
		xlog("Too many channels for customer");
		sl_send_reply(403, "Forbidden");

		if (!cnxcc_terminate_all("$var(client)")) {
			xlog("Error terminating customer's calls");
		}

		exit;
	}
