changing global value at runtime is possible in 3.1 via config parameter
reload framework.
For a per user value, you can script it in config, but starting with
version 1.5, using pseudo-variable class $ul(...):
http://kamailio.org/docs/modules/1.5.x/registrar.html#id3057709
It should look like (well, config for 3.1, but should be valid for :
# Check if maximum registered contacts per aor exceeded - limit
value in $avp(max_regs)
if (reg_fetch_contacts("location", "$tu", "reg"))
{
$var(i) = 0;
$var(found) = 0;
if($ulc(reg=>count)>0 && is_present_hf("Contact")) {
$var(contact) = $(ct{tobody.uri});
while($var(found) == 0 && $var(i) < $ulc(reg=>count)) {
if($var(contact)==$(ulc(reg=>addr)[$var(i)]))
$var(found) = 1;
else
$var(i) = $var(i) + 1;
}
}
if ($var(found) == 0 && is_present_hf("Contact")) {
# - check against max val
if($ulc(reg=>count)>=$avp(max_regs))
{
# too many registrations
sl_send_reply("403", "Too Many Registrations");
exit;
}
}
}
The idea is: fetch the contacts and iterate through it to match the
address. If there is no match, then it is a new contact and check
against the limit.
Hope it helps!
Cheers,
Daniel
