[OpenSIPS-Users] resending the ACK to itself

oops, sorry, i sent the message without finishing :S here i go again:
I've found a "solution" for this problem, the problem was that i had the ip
addres of the Asterisk server on the table "domain";
I have this configuration on my script: (only the important section to be
checked)
if (!(method=="REGISTER") && is_from_local()) /*multidomain version*/
{
if(!check_source_address("0")){
if (!proxy_authorize("", "subscriber")) {
proxy_challenge("", "0");
exit;
}
if (!db_check_from()) {
sl_send_reply("403","Forbidden auth ID");
exit;
}
consume_credentials();
## # caller authenticated
}
}
# preloaded route checking
if (loose_route()) {
xlog("L_ERR",
"Attempt to route with preloaded Route's [$fu/$tu/$ru/$ci]");
if (!is_method("ACK"))
sl_send_reply("403","Preload Route denied");
exit;
}
.
.
.
if (!is_uri_host_local())
{
if(is_from_local()) {
route(1);
} else {
sl_send_reply("403","Not Here");
}
}
Now my doubt is about the permission section (address table), if i delete
the ip address of my Asterisk from the address table the proxy will always
process the request from it, so i do not understand the purpose of the line
if(!check_source_address("0")) after if (!(method=="REGISTER") &&
is_from_local()), as any request coming from the Asterisk will have a FROM
different from the OpenSIPS domain...so that's why i entered the ip of the
Asterisk on the domain table because the is_from_local checks the host part
of the domain table
Is there any explanation about this, am i missing something?
Best Regards!
