Is there a way that I can pass variable into

setid; for

ds_select_dst("avp(customer_setid)",
"4"). I've tried, but it did not
work. Please advise.
A look in modules/dispatcher/dispatcher.c reveals that ds_*()
functions do not parse pseudovariables, which is a problem with a lot
of existing Kamailio code. Any arguments you pass to it will be
interpreted as literal strings.
In short, you can't do that. You may wish to put in a feature request
to update these functions to take pseudovariables.

I haven't looked at the code but I'm using the ds_select functions in
more or less the same way in kam 1.5. I pull the setid from a match in
the dialplan module instead of a db.
if (ds_select_domain("$avp(s:dpattr)", "0")) {
if ($avp(s:dispatcher-cnt) > 1) {
# If there is more than one entry returned for the group
arm the failure route
t_on_failure("ROUTE_DP_FAILURE");
}
route(ROUTE_RELAY);
} else {
xlog("L_WARN", "KAM_HOST: ($ci) $pr $mi route[$rm][0] $fu -> $ru
- No dst gateways found\n");
sl_send_reply("404", "No destination gateways found\n");
exit;
}
OP - Did you try it?
