UAC register - sr-users

11 Jul 2018

Hi,

I’m wondering if there is a flag somewhere in the UAC module config that prevents remote
registration from happening.

It looks like I’ve loaded the uacreg table but I can’t see any REGISTER methods being sent
from Kamailio to the remote peer.

The remote registrants are loaded using this config:

listen=udp:172.16.176.150:5060

loadmodule "db_postgres.so"
loadmodule "kex.so"
loadmodule "corex.so"
loadmodule "tm.so"
loadmodule "tmx.so"
loadmodule "sl.so"
loadmodule "rr.so"
loadmodule "pv.so"
loadmodule "maxfwd.so"
loadmodule "textops.so"
loadmodule "siputils.so"
loadmodule "xlog.so"
loadmodule "sanity.so"
loadmodule "ctl.so"
loadmodule "cfg_rpc.so"
loadmodule "counters.so"
loadmodule "uac.so"

modparam("uac", "reg_db_url", DBURL)
modparam("uac", "reg_contact_addr", “172.16.176.150:5060")
modparam("uac", "reg_db_table", "uacreg")
modparam("uac", "reg_timer_interval", 10)
modparam("uac", "reg_retry_interval", 10)

request_route {
  route(RELAY);
}

route[RELAY] {

  t_on_reply("MANAGE_REPLY");

  if (!t_relay()) {
    sl_reply_error();
  }
  exit;
}

And it looks like this has been consumed by Kamailio:

$ kamcmd uac.reg_dump
{
	l_uuid: 2cc6776d-61ed-4ea1-a3ae-055f89bd4d3f
	l_username: 126231943099723776
	l_domain: 172.16.176.150
	r_username: 1000
	r_domain: 172.16.176.129
	realm: 172.16.176.129
	auth_username: 1000
	auth_password: password
	auth_proxy: sip:172.16.176.129:5080
	expires: 0
	flags: 0
	diff_expires: -1531235076
	timer_expires: 0
	reg_init: 1531234841
	reg_delay: 0
}

Doing a refresh successfully reloads the uacreg data

$ kamcmd uac.reg_refresh 2cc6776d-61ed-4ea1-a3ae-055f89bd4d3f

I can get Kamailio to forward an OPTIONS message to the remote peer () to verify network
connectivity, e.g. :

$ru = "sip:1000@172.16.176.129:5080";
$fs = "udp:172.16.176.150:5060";

But Kamailio does not appear to generate REGISTER messages either after first boot or as a
result of the manual refresh.

This is using an instance of Kamailio 5.0.1. Should I try with a newer version?

Is there a way to get extra debugging of the uac module?

If I increase the debug verbosity, I get quite granular detail for the DB traffic, but the
uac module doesn’t appear to emit much diagnostics.

Many thanks,

Ben
