Hello Alex, 

The log showing $ru value $du, empty. 


$avp(oexten) = $rU; 
if (!lookup("location")) { 
xlog("L_INFO", "This $rU and this $du"); 

Mar 26 03:12:16 dsm01 /usr/sbin/kamailio[9706]: INFO: <script>: This 124 and this <null> 
Mar 26 03:12:57 dsm01 /usr/sbin/kamailio[9709]: INFO: <script>: This 120 and this <null> 

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

Slava.

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?
