Hi, I read in LCR doc:
1.4.4. to_gw([group-id])
Checks if in-dialog request goes to a gateway. If an optional group-id is
given, only gateways belonging to this group are checked.
I suppose that a gateway uses its scheme:IP:port as "Contact" in 200 OK,
so "to_gw()" function matches that scheme:IP:port in RURI and verifies if
there is a To tag to match an in-dialog message and deliver it to gateway. Is
it?
Thanks for any explanation.

it does do do anything that complicated. just checks if ip address in
request uri matches that of a gateway.

I have no experience on this, but couldn't be possible a gateway inserting a
domain isntead of him IP?
Thanks.

everything is possible, but those gateways that i have dealt with,
insert their ip address in contact header. if your gw does insert its
domain name, then you need to start writing another function that can
cope with domain names. you also need to add a domain name field to
gateway table.
