Hello,

"ds_is_from_list" function from Dispatcher module give false result - when actually it should be true.

modparam("dispatcher", "db_url",DBURL)
modparam("dispatcher", "table_name", "dispatcher")
modparam("dispatcher", "setid_col", "setid")
modparam("dispatcher", "destination_col", "destination")
modparam("dispatcher", "flags", 2)
modparam("dispatcher", "dst_avp", "$avp(AVP_DST)")
modparam("dispatcher", "grp_avp", "$avp(AVP_GRP)")
modparam("dispatcher", "cnt_avp", "$avp(AVP_CNT)")
modparam("dispatcher", "sock_avp", "$avp(AVP_SOCK)")

request_route {

xlog("L_INFO","[=Start Routing=]")

if(ds_is_from_list()) {
xlog("L_INFO","[=FROM ASTERISK=]");
} else {
xlog("L_INFO","[=TO ASTERISK=]");
}

if($si=="192.168.1.10") {
xlog("L_INFO","[=FROM ASTERISK BY IP=]");
} else {
xlog("L_INFO","[=TO ASTERISK BY IP=]");
}
