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
