[OpenSIPS-Users] loose_route: loop on ACK requests

[Noel R. Morais]

Sorry.

I forgot the route(1). Follow bellow:
route[1] {
	if (!t_relay()) {
		sl_reply_error();
	};
	exit;
}

I think that my problem is regarding the loose_route() function. I
just don't know why it doesn't "realize" that the Route: header is to
itself. :(

Thanks,


Noel
