Hi Richard,
I might not get the full complexity of your setup.
But if the documentation is correct it should work like this (note the use of $su instead
of $sut):
$xavp(reg=>match_received) = $su;
if (registered("location ", "$fu", 2)) {...}
It looks that you just need to specify a valid URI, it should ignore it then by the xavp
set.
Cheers,
Henning

Subject: Re: [SR-Users] [REGISTRAR] Registered. How to match $sut to usrloc received ?
Made some progress. Always good to step away for a bit.
modparam("registrar", "xavp_cfg", "reg") has been added.
$xavp(reg=>match_received) = $sut;
if (registered("location", "$sut", 2, 1)) {
$var(avariable) = $(xavp(ulrcd[0]=>contact){uri.user});
But still not matching. Where I think I'm getting stuck is while the url field is
"optional", I'm not sure what the right syntax is for it to acknowledge the
optional url isn't there and to not process the match_option section as the url
instead.
If I go with
$xavp(reg=>match_received) = $sut;
if (registered("location", 2, 1)) {
$var(nico) = $(xavp(ulrcd[0]=>contact){uri.user});

Hey Kamailio Users,
So the scenario is we get the registers. Load them, slightly oddly as
we also fill in the received section, not something I usually do.
Then when they send an invite, the To and From headers are real phone
numbers and for some reason the contact header isn't their username.
So to compensate for that I'm trying to match their connection ($sut)
using registered, but after a couple of hours I haven't been able to
get it to match up. Not sure what I'm missing.
ul.dump gets me
Received: sip:sipclientpublicip:2353;transport=udp
so we know that part is loading $sut correctly into the user location data.
modparam("usrloc", "matching_mode", 2)
modparam("registrar",
"xavp_rcd", "ulrcd") modparam("registrar",
"received_avp",
"$avp(i:42)")
$xavp(regcfg=>match_received) = $sut;
if (registered("location","$sut", 2, 1)) {
After that block of code $sut is sip:
sipclientpublicip:2353;transport=udp which is what's in usrloc for
received, but it's not match.
There's probably a much smarter way of doing this that I've completely
missed, if so then that'd be excellent. But if I'm on the right path
somewhat then it would be great to get this working.
