[OpenSIPS-Users] not sure about flags usage and cdrtools

Hi everyone,

I use opensips+cdrtool and I've got the following issue, for some reason 
the radacct table's (1 table per month) canonicaluri column of the my 
radius database is not always been populated.
The cdrtools install guide says that:

It is critical to save $avp(s:can_uri) after the Proxy has performed all 
possible lookups except DNS. The Canonical-URI will be used for rating 
the session. Example:

route {
       ...
       setflag(ACCOUNTING_FLAG);
       $avp(s:can_uri) = $ru;
       ...
}

I'm not really sure when does the the proxy performs the DNS lookup on 
my script, but basically I uncommented the example script that comes 
with opensips to enable DB registration, lookup and when the user can't 
be found by the location module, it let the carrierroute module handle 
the call (of course I already got several carriers on my DB).  But the 
truth is that I never tried to set the $avp(s:can_uri), because I'm not 
sure where to put it.

Here is the script is there any way to ensure that the canonicaluri (and 
destinationid) columns will always get populated?

Thanks very much for your help.
