Hi Klaus,
The best location of applying such a
"policy" function depends on
several things:
First, you need to have all the data you are requiring. E.g. if you want
to check if a certain user is allowed to call a certain phone number you
usually need to do first:
- authenticate the user
- normalize destination (e.g. bring phone number into E164 format or
apply alias lookups).
Basically any user should authenticate as usual, than before
two
user can talk together, kamailio must authorize the conversation
through a SQL lookup
Then, before proceeding any further, you might
check the policy using a
SQL query. Be sure to SQL escape the date you provide for the SQL lookup
to prevent SQL injection (see "transfomations").
In above case, the SQL query should be before calling lookup().
So, digging in the
code you mean something like:
# USER location service
route[LOCATION] {
<SQL lookup code goes here>
#!ifdef WITH_ALIASDB
# search in DB-based aliases
alias_db_lookup("dbaliases");
#!endif
if (!lookup("location")) {
switch ($rc) {
case -1:
case -3:
t_newtran();
t_reply("404", "Not Found");
exit;
case -2:
sl_send_reply("405", "Method Not
Allowed");
exit;
}
}
# when routing via usrloc, log the missed calls also
if (is_method("INVITE"))
{
setflag(FLT_ACCMISSED);
}
} # USER location service
route[LOCATION] {
#!ifdef WITH_ALIASDB
# search in DB-based aliases
alias_db_lookup("dbaliases");
#!endif
<SQL lookup code goes here>
if (!lookup("location")) {
switch ($rc) {
case -1:
case -3:
t_newtran();
t_reply("404", "Not Found");
exit;
case -2:
sl_send_reply("405", "Method Not
Allowed");
exit;
}
}
# when routing via usrloc, log the missed calls also
if (is_method("INVITE"))
{
setflag(FLT_ACCMISSED);
}
}
