Hi,
I am looking to restrict calls based on destination numbers, e.g. so people
can't call premium rate etc. Which module is best to achieve this?
Thanks,
Keith

Replacing the exit statement with return, does the trick. The reply reaches the onreply_route and that's where I add the header, but after a while it generates a 483 Too Many Hops.
My capture server also receives a lot of INVITE, ACK, 603 messages. A lot of Via and Record-Route headers are added to the INVITE and 603 (Via only).
Why does this happen?

Subject: [SR-Users] append_hf to reply generated by kamailio
Hello,
Is it possible to append a new header to a reply generated by Kamailio and also have it present when duplicating the message to a capture server?
At the moment the 603 Reply is duplicated to my capture server, but I don't know how to append a new header, because the kamailio script stops executing after exit is called.
>From what I understood: onreply_route is only executed when receiving replies.
Is there a reply_route which is executed for all replies, including the ones generated by kamailio itself?
For instance inside this code block:
request_route {
.....
if($var(routing_query_result) =~ "DESTINATION_NOT_ALLOWED") {
xlog("L_INFO", "[R-CORE-INCOMING-INVITE:$ci] !>" "Rejecting the call, because the destination is not allowed\r\n");
sl_send_reply("603", "Decline");
exit;
}
.....
}

My bad, I forgot to make something clear.
The IF statement is in a different route which is called by de main request_route. So when the return statement is executed the control is passed back to the main request_route, which in turn relays the INVITE back to itself. That's probably causing the 483 Too Many Hops response?

Use append_to_reply(txt) before sl_send_reply():

We use something like this:
if ((uri =~ "^sip:90[0-9]{6}@.*") &&
(!avp_check("$avp(s:perms)","re/9/g"))) {
xlog("$ru : No permissions to call 90X numbers ($ci)");
sl_send_reply("403", "No permissions to call 90XXXXXX");
exit;
}
and then store the information in usr_prefences table.
