Hello Norman,
thanks, Norman
after I have closed the domain authorisation (proxy_authorize), everything works.
It looks for me too sophisticated to use permission and domain module. I will try
another method.
now I want to make restrictions for voip users, I mean who has the right to make a call
to pstn
and who has not. someone has some ideeas?

Hello Ion,
Perhaps the "pstn" device is not responding
to the authorization
request. A SIP trace will show you if this is happening.
"ngrep -W byline port 5060" should be all
you need to trace SIP messages
(if you're listening on eth1, then you might want to add "-d eth1" when
invoking ngrep). Older versions of ngrep did not have the "-W byline"
option. If this is your case, you probably should upgrade ngrep.
A possible solution to you problem might be to use the
"permissions"
module and the "trusted" table. Then, instead of
(www_authorize/www_challenge or in addition to, depending on your
particular situation) you might want to use the "allow_trusted()"
command to authenticate incoming INVITEs.
Below is a little example
<snip>
if (!is_from_local() &&
!allow_trusted()) {
if (!proxy_authorize("","subscriber")) {
proxy_challenge("","0");
exit;
} else if (!check_from()) {
sl_send_reply("403", "Use From=ID");
exit;
};
};
</snip>
Regards,
Norm
