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?
Thank you,
Alejandro Rios Peña
