Kamailio 3.1.2 Here is my setup:

Phone1 (10.10.1.114) | Kamailio (10.10.1.230) / \ / \ Freeswitch1 Freeswitch2 ----------------------> Other phones (10.10.1.222) (10.10.1.223)

Both Freeswitch's share the same REGISTRATION information. Phone1 is already registered with Freeswitch. When I try to dial 'Other phones' using phone1, the dispatcher always get into FAILURE route although the log shows that kamailio did send INVITE to 10.10.1.222 and received '407 - Proxy Authentication Required' from Freexwitch1 and then dispatcher send INVITE to 10.10.1.223 and also received '407 - Proxy Authentication Required' from Freexwitch2 and eventually failed.

Any idea?

Here is my configuration:

modparam("dispatcher", "db_url", DBURL) modparam("dispatcher", "table_name", "dispatcher") modparam("dispatcher", "ds_ping_interval", 10000) modparam("dispatcher", "ds_probing_threshhold", 3) #modparam("dispatcher", "ds_ping_reply_codes", "class=2;class=4") modparam("dispatcher", "ds_ping_method", "OPTIONS") modparam("dispatcher", "ds_probing_mode", 1) modparam("dispatcher", "ds_ping_from", "sip:proxy@SIP-router1.testnet.net") modparam("dispatcher", "dst_avp", "$avp(dsdst)") modparam("dispatcher", "grp_avp", "$avp(dsgrp)") modparam("dispatcher", "cnt_avp", "$avp(dscnt)") modparam("dispatcher", "attrs_avp", "$avp(dsattrs)") modparam("dispatcher", "flags", 3) modparam("dispatcher", "force_dst", 1)

route { ....

if ( ds_select_dst("$var(group)", "9") ){ route(RELAY_DS); return; ... }

route[[RELAY_DS] if (is_method("INVITE")) { t_on_branch("BRANCH_ONE"); t_on_reply("NAT_REPLY"); t_on_failure("FAIL_DS"); } if (!t_relay()) { sl_reply_error(); } }

failure_route[FAIL_DS] { if (t_check_status("408")) { ds_mark_dst("i"); } if (!ds_next_dst()) { t_reply("503", "Service unavailable: no more dst"); exit; } t_on_failure("FAIL_DS"); route(RELAY_DS); }

onreply_route[NAT_REPLY] { xlog("L_INFO", "REPLY_ROUTE: S=$rs - $rr F=$fu T=$tu IP=$avp(s:ip):$avp(s:port) ($si:$sp) ID=$ci\n");

}

And here is the SIP messages from ngrep:
