[SR-Users] load balancing redirect

Hi, I'm trying to setup Kamailio to act as a load-balancer in front of asterisk servers. I want it to do the following: - The UA sends an invite to Kamailio - Kamailio sends a 30x redirect to the UA (dispatcher) - The UA sends it's invite to the asterisk server I've seen a couple of examples, but doesn't seem to work for me. Here's the relevant config: route{ if (method=="REGISTER") { [...clip...] }; if (method=="INVITE") { ds_select_domain("2","8"); #ds_select_dst("2","8"); sl_send_reply("300","Redirect"); exit; }; } What seems to happen is that Kamailio does send the redirect, but with no indication of where to go. ds_select_domain (or ds_select_dst ... I having trouble understanding the difference like many people it seems) I'm guessing selects an appropriate uri, but doesn't put it the contact for the redirect. Is there anyway to see what was set by the ds_select_dst? what pv would have this value? What do I need to set prior to sending a redirect reply for it to be properly forwarded? BTW: using Kamailio 3.0.1 Thank you, -- Benjamin
