That's what I'm looking for. Thank you very much.
Here is my final script:
reg_fetch_contacts("location", "sip:gatewaynum...@mydomain.com", "pstn");
if($(ulc(pstn=>count))){
$ru = "sip:" + $rU + "@" + $(ulc(pstn=>addr){uri.host}) + ":"
+ $(ulc(pstn=>addr){uri.port});
} else {
# fall back to old ddns style gateway address
$ru = "sip:" + $rU + "@" + $sel(cfg_get.pstn.gw_ip);
}
route(RELAY);
