[SR-Users] LCR next_gw() - certain GW, source from other IP address

[Graham Wooden]

Stagg, 

While the Ips are the same, the suggestion to use “rd” along with an entry
in the “hostname” column appears to be what I want.

I assigned in my DNS some testing hostnames to the single IP in question.
When debugging, I see that rd contains the hostname, not the IP.  I believe
with that, I can differentiate between the two... And when I see hostname of
blah.blah.tld, then go ahead and do the force_send_socket.

This definitely solves the issue for the time being. However, I am wondering
if/when call volume increases if the call-setup time be delayed because of
these look ups.  Everything that I have read so far is that the gw_name is
just information, the module doesn’t actually have access to it. Boo.
