Hi Daniel
You may want to kill me but I'll be honest, I'm actually using kamailio's 1.5 UAC module on an Opensips 1.6.2 :$ so I don't know if the problem could be related to that. Anyway, here is the bad register message when using only $uac_req(ruri)="sip:8.14.80.37:5061". Note that the SIP part itself its correct, but the UDP destination port is wrong:
Internet Protocol, Src: 8.14.80.16 (8.14.80.16), Dst: 8.14.80.37 (8.14.80.37) User Datagram Protocol, Src Port: sip-tls (5061), Dst Port: sip (5060) C%E@@PP% REGISTER sip:8.14.80.37:5061 SIP/2.0 Via: SIP/2.0/UDP 8.14.80.16:5061;branch=z9hG4bK9b35.3e435b31.0 To: sip:LV-SKRUPPA@8.14.80.37 From: sip:LV-SKRUPPA@8.14.80.37;tag=a649c0188a5a7b7f4a4dfeaea88004c3-b5bd CSeq: 10 REGISTER Call-ID: 52d42e13484b4229-29572@8.14.80.16 Content-Length: 0 User-Agent: OpenSIPS (1.6.2-notls (x86_64/linux)) Contact: sip:LV-SKRUPPA@8.14.80.16:5061 Expires: 60
I hope this can be of any help.
Kind regards,

Hello Daniel
Thanks for pointing out to the SIP traces. I found out that it if the request is to be sent to a destination using a port other than 5060, it is required to add the $uac_req(ouri) parameter too:
$uac_req(ouri)="sip:" + $var(asterisk_ip) + ":" + $var(asterisk_port); ....
$uac_req(ouri)="sip:" + $var(asterisk2_ip) + ":" + $var(asterisk2_port);
Interesting, it should work when changing the 'ruri' attribute as well. Can you send a sip trace with changed r-uri for the two requests that go to wrong destination?
Thanks, Daniel
Thanks!

Hi all,
I am testing the scenario described here: http://kb.asipto.com/asterisk:realtime:kamailio-3.1.x-asterisk-1.6.2-astdb
It works great with one instance of Asterisk, but now that I'm testing with two Asterisk instances to load balance, and I see a problem regarding the registration forwarding to the second Asterisk.
I tried adding a second "uac_req_send()" bellow the first one, but Kamailio only sends the first request and the REGISTER never gets to the second Asterisk:
# Forward REGISTER to Asterisk route[REGFWD] { if(!is_method("REGISTER")) { return; } $var(rip) = $sel(cfg_get.asterisk.bindip); $uac_req(method)="REGISTER"; $uac_req(ruri)="sip:" + $var(rip) + ":" + $sel(cfg_get.asterisk.bindport); $uac_req(furi)="sip:" + $au+ "@" + $var(rip); $uac_req(turi)="sip:" + $au+ "@" + $var(rip); $uac_req(hdrs)="Contact:<sip:" + $au+ "@" + $sel(cfg_get.kamailio.bindip) + ":" + $sel(cfg_get.kamailio.bindport)
- ">\r\n"; if($sel(contact.expires) != $null) $uac_req(hdrs)= $uac_req(hdrs) + "Expires:" +
$sel(contact.expires) + "\r\n"; else $uac_req(hdrs)= $uac_req(hdrs) + "Expires:" + $hdr(Expires) + "\r\n"; uac_req_send();
$uac_req(all) = null; $var(rip2) = $sel(cfg_get.asterisk2.bindip); $uac_req(method)="REGISTER"; $uac_req(ruri)="sip:" + $var(rip2) + ":" +$sel(cfg_get.asterisk2.bindport); $uac_req(furi)="sip:" + $au+ "@" + $var(rip2); $uac_req(turi)="sip:" + $au+ "@" + $var(rip2); $uac_req(hdrs)="Contact:<sip:" + $au+ "@" + $sel(cfg_get.kamailio.bindip) + ":" + $sel(cfg_get.kamailio.bindport)
- ">\r\n"; if($sel(contact.expires) != $null) $uac_req(hdrs)= $uac_req(hdrs) + "Expires:" +
$sel(contact.expires) + "\r\n"; else $uac_req(hdrs)= $uac_req(hdrs) + "Expires:" + $hdr(Expires) + "\r\n"; uac_req_send();
}
I also tried appending another branch and sending the second uac_req_send() from there, but it is not being sent.
How can I use uac_req_send() several times for the same request or in parallel?
it should work one after the other. append_branch() does not affect uac_req_send() at all, this is a separate request built from scratch.
Do you get any error message in the syslog? Can you watch the traffic on all interfaces 'ngrep -d any -qt -W byline port 5060' ?
I see you assign '$uac_req(all) = null;', it should be '$uac_req(all) = $null;' - but I guess it was a copy&paste thing.
Cheers, Daniel
