Hey Daniel,

Thanks a lot for your help.

do you have #!SER as first line? This part should be the same ... if pv not found, then it should be considered avp. I will try to see what is the issue.

I don't have #!SER
 
Anyhow, for the moment, if not working, load pv and then try:
- $fd and $td must stay as parameters for lookup_domain()
- for strempty() try to use $avp(fd.did) and $avp(td.did)

I loaded pv, and modified the script accordingly. No syntax errors anymore, but avps are not populated from the data stored in the db. Maybe a problem with lookup_domain?

Here's the excerpt of the script (I replaced the selects with '@' by '$sel()', and added a dump_attrs()) :
        xlog("L_INFO", "from.uri.host : $sel(from.uri.host)\n");
        xlog("L_INFO", "ruri.host : $sel(ruri.host)\n");

        lookup_domain("$fd", "$sel(from.uri.host)");
        lookup_domain("$td", "$sel(ruri.host)");

        xlog("L_INFO", "fd : $avp(fd.did)\n");

        dump_attrs();

        if (strempty($avp(fd.did)) && strempty($avp(td.did))) {
                # Neither the calling nor the called domain is local
                # This is a relaying attempt which should be forbidden
                sl_reply("403", "Relaying Forbidden");
                drop;
        }

And as a result :
0(22008) INFO: <script>: from.uri.host : ext.test.r3load.voip
 0(22008) INFO: <script>: ruri.host : ext.test.r3load.voip

In the db :

|  1 | ext.test.r3load.voip | ext.test.r3load.voip |     0 |

Thanks again!
