Hello Alex,

Yes, all question that when I am checking location table I see only records for asterisk box, no information about registered extension. Do you think is will good idea put save location after authentication in request route section ?

Which another part is domain is empty and username empty.

Slava.

Hello Alex,

That make sense, because all 3 digit extension which in log belong to voicemail server. They not local set it located on asterisk box. Also I see 484.

In this case do I need test if it local set or not ?

Yeah, but you're checking inside the if(!lookup(...)) block.

! is, in Kamailio, as in most programming language languages, a negation operator. It means "if the lookup failed" in this case, i.e. if lookup() returned a zero or negative value. And if you're seeing the xlog messages where you have placed them, it means the lookups are failing.

It also means the RURI is not being altered by a successful lookup, which means it still has the RURI domain of the proxy (print $ru, not $rU, to see what I mean), which explains the request looping.

Hello Alex,

The log showing $ru value $du, empty.

        $avp(oexten) = $rU;

When I specify proxy settings on sip client "zoiper", rtp start working and at least I can dial voicemail on asterisk behind.

That sounds like the registration lookup is resolving to a binding which has as its domain the domain of the proxy itself.

Try printing the value of $ru and $du (via xlog) immediately after the lookup(). It will probably shed some light.

Hello Alex.
After some looking around, I added in request route,

Added

        # Saving domain + attr in DB
        save("location");

        # user location service
        route(LOCATION);
}

but the problem that call looping. If I dial any extension call back to dialed extension. I see on tcpdump like.

Hello Alex,

I was looking on location as far I understand this part need to be checked on ldap level.

        $avp(oexten) = $rU;
        if (!lookup("location")) {
                $var(rc) = $rc;

I have defined in ldap as separate item sipDomain I can do ldap_search on it, but not sure about lookup, avp I can set to $avp(domain).

Hello Alex,

Here output from dig.

Yes, for current setup I want setup as border gateway with couple redirection and failover to DR site. Currently I got ldap authentication working. trying test call between remote extension (which failing). And next step will forward to voicemail which partially done. PSTN forward is part of config I will need adjust couple expression to match dial string. That current plan.

How are you checking the SRV records, exactly? Can you paste the
invocation and output of the 'host' command, or whatever you're using?
