Answered my own question . . In function fixstringloadgws in /modules/lcr/lcr_mod.c . . if(str2int(&s, (unsigned int*)&model->spec.pvp.pvn.u.isname.name.n)!=0 || model->spec.pvp.pvn.u.isname.name.n<100) { As called by: static cmd_export_t cmds[] = { {"load_gws", load_gws, 0, 0, 0, REQUEST_ROUTE}, {"load_gws", load_gws_grp, 1, fixstringloadgws, 0, REQUEST_ROUTE}, {"next_gw", next_gw, 0, 0, 0, REQUEST_ROUTE | FAILURE_ROUTE}, {"from_gw", from_gw, 0, 0, 0, REQUEST_ROUTE | FAILURE_ROUTE | ONREPLY_ROUTE}, {"from_gw", from_gw_grp, 1, fixup_str2int, 0, REQUEST_ROUTE | FAILURE_ROUTE | ONREPLY_ROUTE}, {"to_gw", to_gw, 0, 0, 0, REQUEST_ROUTE | FAILURE_ROUTE}, {"to_gw", to_gw_grp, 1, fixup_str2int, 0, REQUEST_ROUTE | FAILURE_ROUTE}, {"load_contacts", load_contacts, 0, 0, 0, REQUEST_ROUTE}, {"next_contacts", next_contacts, 0, 0, 0, REQUEST_ROUTE | FAILURE_ROUTE}, {0, 0, 0, 0, 0, 0} }; I was using values under 100, as the default value in the docs is "1". When I set the group ids at 100 or higher, it works just fine. Hate to answer my own questions, but thought I should so we can update the docs. - Darren On 5/1/08 2:48 PM, "Darren Sessions" &lt;dsessions(a)icidirect.net&gt; wrote: Question . .

Per the docs at http://www.openser.org/docs/modules/1.3.x/lcr.html#AEN303 , I should be able to use a particular gateway group id in that function. My config code excerpt: if (from_gw("1000")) { xlog("L_ERR", "Route 14: Call originating from incoming vendor\n"); if (!load_gws("2")) { xlog("L_ERR", "Route 14: Error loading gateways (GW Group 2) - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n"); sl_send_reply("503", "Termination Currently Unavailable"); exit; } if (!next_gw()) { xlog("L_ERR", "Route 14: No gateways available (GW Group 2) - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n"); sl_send_reply("503", "Termination Currently Unavailable"); exit; } setflag(21); t_on_failure("1"); route(10); } Basically, it's checking to see if the call is originating from one of the incoming gateways in group id 1000, and if it is, I'd like to pull a gateway from group 2 and send the call to it. Any help would be appreciated. Thanks, - Darren
