Great! That worked

Hi,
your problem is, that you are using round robin for registration (method 4). The system creates a nonce value and validates this. Normally, only the system which generated the nonce can validate it (this should apply for the Asterisk, in the Kamailio Authentication you may configure this, http://kamailio.org/docs/modules/1.5.x/auth.html#id2510477). So we have to make sure, that both the original INVITE/REGISTER and the following INVITE/REGISTER reach the same server.
In your case, you should use a different algorithm (Please see http://kamailio.org/docs/modules/1.5.x/dispatcher.html#id2468101). Probably algorhitm "0" would be best for you (Hash over Call-ID). For your requests you should replace " ds_select_dst("1","4");" with " ds_select_dst("1","0");" and your authentication should work.

I just noticed that if I have 4 servers set like this
# group sip addresses of your * units 1 sip:XXX.XXX.XXX.XXX:5060 1 sip:XXX.XXX.XXX.XXX:5060 1 sip:XXX.XXX.XXX.XXX:5060 1 sip:XXX.XXX.XXX.XXX:5060
the registration does not work and I get 401 unauthorized.
My setup is like this
Openser as proxy sends all SIP messages to load balanced asterisk servers So sip phones should be able to register to the asterisk server
The routing part in kamailio.cfg looks like this
if ( method=="REGISTER" || method=="NOTIFY" || method=="OPTIONS" || method=="ACK" || method=="MESSAGE") { fix_nated_contact(); fix_nated_register(); ds_select_dst("1","4"); forward();#uri:host, uri:port); exit();
}
if (method=="BYE" || method=="CANCEL") { unforce_rtp_proxy(); } else if (method=="INVITE"){ log("VCTOR: Got an invite\n"); fix_nated_contact(); force_rtp_proxy(); ds_select_dst("1","4"); forward();#uri:host, uri:port); t_on_failure("1"); };
search_append('Contact:.*sip:[^>[:cntrl:]]*', ';nat=yes');t_on_reply("1");
if (!is_method("INVITE|REGISTER|MESSAGE|BYE|NOTIFY|ACK|CANCEL|REFER|SUBSCRIBE|OPTIONS|INFO")) { xlog("L_INFO", "=== [$rm] Method Not Implement ===========\n");
sl_send_reply("501", "Not implemented here"); return; };
any thoughts?
