Thanks,
That configuration is accepted but now my "registered" client is denied at both following lines:
if (!lookup_user("From")) {
check if the From HF is the same in the INVITE as the To HF in the REGISTER, and check the uri table in your database
if ((!avp_equals_xl("$registered_host", "%si") || !avp_equals_xl("$registered_port", "%sp"))) {
How can I print $registered_host to log ?
xlog("L_ERR", "registered_host = %$registered_host \n");
I can print %si with xlog().
I guess xlog("L_ERR", "src ip = %si \n");

Thanks Miklos,
I think this is just what I'm looking for. But I get some errors for this line: if ((src_ip != @ruri.host) || (src_port != @ruri.port)) {
You can access src_ip and src_port via xl_lib:
$registered_host = @ruri.host; $registered_port = @ruri.port;
if ((!avp_equals_xl("$registered_host", "%si")) || (!avp_equals_xl("$registered_port", "%sp"))) { ...

Any idea why ?

Hi Ilker,
just my first idea, not tested:
- lookup the From HF
if (!lookup_user("From")) { # reject the INVITE ... }
- save original To UID and Request URI
$orig_to_uid = $tu.uid; $orig_req_uri = @ruri;
- set To UID -- registrar module will use this in the lookup
$tu.uid = $fu.uid;
- lookup >From HF and compare the source address of the INVITE with
the source address of the REGISTER message
if (lookup("location")) { if ((src_ip != @ruri.host) || (src_port != @ruri.port)) { # reject the INVITE ... } # restore original To UID and Request URI $tu.uid = $orig_to_uid; attr2uri("$orig_req_uri"); } else { # reject the INVITE ... }
Note, that the above solution is a bit ugly, you can get into troubles when the user registers multiple contact addresses. It is better to disable branches (see append_branches parameter in registrar module), but you loose some functionality.
Regards, Miklos

In that case I think the best way is to lookup location table for

If the source URI location matches the location in that table then

How can I configure this ?

if (method=="REGISTER") { if(!src_ip=="other") { if (!www_authorize("gtstelecom.ro", "subscriber")) { www_challenge("domain", "0"); break; }; save("location"); log("Replicating REGISTER\n"); t_replicate("other", "5060"); } else { save("location"); }; break; } else { # this is an INVITE if (!proxy_authorize("gtstelecom.ro", "subscriber")) { proxy_challenge("domain", "1"); break; }; # route the call ... };

Hi all,
Is it possible to prevent any user calling without registering ?

I guess I'll have to check if the source URI exists in location
table.
What is the easiest way to do this ?
If there is a more robust way to do it, please suggest...
Thanks, ilker
