With the below, we loop through all of the contacts that match $fu, but only unregister
the one matching the $ci of the 200 OK that is associated with the unregister (Expires: 0)
request from the upstream server.
It actually has 3 parts. For completeness, I probably should have added them all.
Below:
route[REGISTRAR] {
….
do stuff
….
if (search_hf("Expires", "^0$", "a")) {
….
do stuff
….
t_on_reply("UNREGISTER");
xlog("L_INFO", "Processing unregister event from $si To:
$tu\n");
route(RELAY);
exit;
}
….
do stuff
….
}
onreply_route[UNREGISTER] {
if (t_check_status("200")) {
route(UNREG);
}
}
route[UNREG] {
reg_fetch_contacts("location", "$fu", "un_reg");
$var(i) = 0;
while ($var(i) < $(ulc(un_reg=>count))) {
$var(ul_callid) = $(ulc(un_reg=>callid)[$var(i)]);
$var(ul_ruid) = $(ulc(un_reg=>ruid)[$var(i)]);
if ($var(ul_callid) == $ci) {
xlog("L_INFO", "Unregistering contact $tu Ruid:
$var(ul_ruid)\n");
unregister("location", "$fu", "$var(ul_ruid)");
$sht(regs=>$fU@$fd~$ci)=$null;
}
$var(i) = $var(i) + 1;
}
}

Beware that since you’re removing all contacts, if any are valid and if any of the
contacts that did not unregister is called, Kamailio won’t find them.
If what you need is not force only one contact per user, maybe look at

Sorted it. I needed to loop through the contacts, then select the correct ruid based on
$ci
For completeness, here is my solution:
reg_fetch_contacts("location", "$fu", "un_reg");
$var(i) = 0;
while ($var(i) < $(ulc(un_reg=>count))) {
$var(ul_callid) = $(ulc(un_reg=>callid)[$var(i)]);
$var(ul_ruid) = $(ulc(un_reg=>ruid)[$var(i)]);
if ($var(ul_callid) == $ci) {
xlog("L_INFO", "Unregistering contact $tu Ruid:
$var(ul_ruid)\n");
unregister("location", "$fu",
"$var(ul_ruid)");
$sht(regs=>$fU@$fd~$ci)=$null;
}
$var(i) = $var(i) + 1;
}

Happy Friday!
To clean up contacts that have sent requests to unregister (Expires: 0) I am executing
the following after a 200 OK response from the upstream server:
reg_fetch_contacts("location", "$fu", "un_reg");
xlog("L_INFO", "Removing unregistered contact From: $si To: $tu Ruid:
$ulc(un_reg=>ruid)\n");
unregister("location", "$fu", "$ulc(un_reg=>ruid)”);
This produces the desired result when there is only one contact per AoR, but when
multiple contacts are present, it seems to delete the first ruid (which makes sense as I
am only providing the $fu).
So, the question, can I select the contact by call-id or some other unique identifier
specific to the desired contact that I can grab from the transaction? Reading the
reg_fetch_contact and unregister docs, they do not seem to provide for selection beyond
uri.
