OK, couple more questions regarding my two options. So far I can potentially use to_gw_grp("1") OR I can use the flags AVP to store a flag which dictates what my send_socket will be. Here are my challenges with each:
1 - to_gw_grp("1"). How would I ensure that subsequent in-dialog requests are sent from the same socket as the original INVITE to my ITSP.
Asterisk --> INVITE --> KAMAILIO --> (next_gw()/to_gw_grp("1")/force_send_socket() --> INVITE --> ITSP Asterisk --> BYE --> KAMAILIO --> (if(loose_route(){t_relay();}) -- BYE --> ITSP
How would I call the to_gw_grp("1") in this scenario? Would I just call it after calling loose_route(), but before calling t_relay()?
2 - using AVP flags. The AVP is only set after the initial call to next_gw(), how would I have access to this flag for in-dialog requests? I could perhaps store it in a htable with call-id as the key and overwrite the value each time we call next_gw() (in the event there are failures)... just not sure this is the best idea.
Thanks to everyone for your time and effort here.
Much appreciated!

OK, I am running into some errors when starting my script:
if(to_gw("1")){ force_send_socket(X.X.X.180:5060); }else if(to_gw("3")){ force_send_socket(X.X.X.179:5060); }else if(to_gw("4")){ force_send_socket(X.X.X.189:5060); }

Perhaps I an confused about how the to_gw() function of the LCR module is
to
be used. In my "gw" table, I have gateways with grp_id 1, 3, and 4. I
am
assuming that is the value I should be checking for in the to_gw()
function,
but it seems to be expecting a pseudo variable or something.
Theorically (according to the LCR documentation), "to_gw()" must be used when processing in-dialog requests. However I'm not sure of the cause of your error, which is exactly the line 384 in your script?
Anyhow I suggest you a different approach:
- Set a different flag for each gw (in LCR 'gw' table) depending on
the sending socket that must be used.
- After calling 'next_gw()' inspect the value of the gw flags (stored
in a configured AVP) and choose which 'force_send_socket()' to use.
