[SR-Users] Relaying ACK to Asterisk

[Igor Potjevlesch]

I just identified that if "IP_KAMAILIO/ASTERISK" is set into domain table,
the issue occured.
If I delete this entry, the ACK is properly relayed.

The thing is that I use domain table for this check in REQ_INIT:
if (!has_totag()) {
                if (!is_uri_host_local()) {
                        if (is_from_local() || allow_trusted()) {
                                xlog("L_WARN","time=[$Tf] call id=[$ci] call
seq=[$cs] contact header=[$ct] from uri=[$fu] from tag=[$ft] request's
method=[$rm] request's uri=[$ru] to uri=[$tu] to tag=[$tt] sip message
id=[$mi] process id=[$pp] ip source=[$si] flags=[$mf],  From the trusted
source\n");
                                return;
                        }
                        else{
                                xlog("L_WARN","time=[$Tf] call id=[$ci] call
seq=[$cs] contact header=[$ct] from uri=[$fu] from tag=[$ft] request's
method=[$rm] request's uri=[$ru] to uri=[$tu] to tag=[$tt] sip message
id=[$mi] process id=[$pp] ip source=[$si] flags=[$mf],  Relay Forbidden\n");
                                sl_send_reply("403", "Relay Forbidden");
                        };
                        exit;
                };
        };

Regards,

Igor.

Hello Klaus,

Thank you for the translation ;)
Here is the config:

/* add local domain aliases */
alias=sip.domain.tld

/* uncomment and configure the following line if you want Kamailio to
   bind on a specific interface/port/proto (default bind on all available)
*/
listen=udp:IP_KAMAILIO/ASTERISK:5060
listen=udp:IP_KAMAILIO_LAN:5060

The 'domain' table is populated as follow:
id | domain
1	<IP_KAMAILIO/ASTERISK>
2	sip.domain.tld
3	<hostname_server>
4	sip.domain.tld

Regards,

Igor.

Something is going wrong here:

That's correct. The ACK is not pre-loaded (with a route set).

Checking first local URI (either alias= or listen= statement)

Checking seconf local URI (either alias= or listen= statement)

Correctly detects that the RURI does not address Kamailio, but

This means, that check_self returned 1 (match) although it didn't matched.
This means that the _check_self_func_list (forward.c) is populated and
matches the RURI.

Thus, the RURI does not match one of the "standard" aliases (the ones
learned by the listen=... statements) but some other module registered a
callback which returns MATCH, and thus Kamailio thinks the previous hop is a
strict router:

> DEBUG: rr [loose.c:724]: after_strict(): The last route URI:
> 'sip:<IP_KAMAILIO_ASTERISK>;lr=on'

please post your complete alias=.... and listen=... config.

Further, I suspect that you register additional aliases via "domain" or
"corex" module and these additional aliases match the RURI. So review your
domain and corex configuration.

regards
Klaus
