Hello, David.
Sorry for the time to reply you. I was a little busy here in the last few
days.
I am not sure about the "==". We had tried it here, but it only worked when
we used with =~. We are currently running kamailio 4.2, so it may be a
problem with our version.
About the $hdr variable, it is used to get information from the SIP
Headers. I am not sure, but I dont think that there is an header with
Instance-ID, so you must try to find how can you get this ID in kamailio,
as I don't know where is it saved.

Hello all!
After some time I was able to get this working here, and now I am coming
back to share my configuration with you guys (in case someone needs to get
this working).
Here is what we have done:
route[REGISTRAR] {
if (is_method("REGISTER"))
{
if(isflagset(FLT_NATS))
{
setbflag(FLB_NATB);
# uncomment next line to do SIP NAT pinging
## setbflag(FLB_NATSIPPING);
}
xlog("L_INFO", "checking $tu registered with
User-Agent:$hdr(User-Agent)\n");
if(reg_fetch_contacts("location", "$tu",
"caller"))
{
xlog("L_INFO", "$(ulc(caller=>count)) records
found for $tu\n");
$var(i) = 0;
while($var(i) < $(ulc(caller=>count)))
{
xlog("L_INFO", "record $var(i) with
ruid:$(ulc(caller=>ruid)[$var(i)]) -
User-Agent:$(ulc(caller=>user_agent)[$var(i)])");
if
($hdr(User-Agent)=~$(ulc(caller=>user_agent)[$var(i)]))
{
$var(ruid) =
$(ulc(caller=>ruid)[$var(i)]);
xlog("L_INFO", "unregistering $tu
ruid:$var(ruid)");
unregister("location",
"$tu",
"$var(ruid)");
}
$var(i) = $var(i) + 1;
}
}
if (!save("location", "0x00"))
sl_reply_error();
exit;
}
}
There are some logs over there because we used it to see what was going on
while testing the configurations.
With this we can get just one register per User-Agent.
And again, thanks Olle for your help in this problem

Sure it is!
This is exactly what I was looking for! Actually I wasn't able to see
that there was a way to perform this action!
Thanks for your help, Olle!
I will try to create this, and when I have it done, I will post my script
here, so if someone else need the same problem I can help.
Now, I have just one more question about my scenario: when I register a
user, is there a way to create something like a "custom field" on the
location? To explain better: If possible, I can add something like a custom
header that says if the user is registered from a phone device or the web
interface, then I can perform the loop and replace only the oldest contact
using that device...

This is my problem... I want to have 2 contacts
for AOR, and not only
one.
When the 3rd arrives, it must remove the oldest and continue with 2...
*If I am using the 0x04 parameter, it will save just one contact, and
the user will not be able to get the Invite both, in the mobile device and
web interface.*

Hello, *Olle!*
*Thanks for your help in this case, and don't worry about the time
(actually I wasn't even expecting to get an answer today).*
*I know the max_contacts parameter. But the problem is that if I set
the max_contacts to 2, when the user tries to register again, he gets an
error message 503. The point is that I want to get the user registered, and
replace the oldest location entry for the newest one.*
