So maybe what I'm getting from your email is that , for this to work the way I expect is to have more unique and random values in my hash_pvar to get the required functionality.

Thanks once again,

Hello,

do you get any errors in the log?

Be aware that hash functions may return same code for different input values. A hash function is guaranteed to return same code for same input value, but there can be collisions of codes for different values.

Cheers,

Hello,

I'm having trouble using algorithm 7 in dispatcher module. Here is my kamailio version. The problem is that despite multiple dispatcher entries corresponding to one set all calls go only to only one destination.

[root@control1 ~]# kamailio -V

Here is the dipacther module params.

# ------- Load-balancer params ------

modparam("dispatcher", "db_url", DBURL)

modparam("dispatcher", "table_name", "dispatcher")

modparam("dispatcher", "setid_col", "setid")

modparam("dispatcher", "destination_col", "destination")

modparam("dispatcher", "force_dst", 1)

modparam("dispatcher", "flags", 3)

modparam("dispatcher", "dst_avp", "$avp(i:271)")

modparam("dispatcher", "cnt_avp", "$avp(i:273)")

modparam("dispatcher", "ds_ping_from", "sip:proxy@109.XXX.2XX.XX")

modparam("dispatcher", "ds_ping_interval",15)

modparam("dispatcher", "ds_probing_mode", 1)

modparam("dispatcher", "ds_ping_reply_codes", "class=2;code=403;code=404;code=484;class=3")

modparam("dispatcher", "hash_pvar", "$avp(i:274)")

modparam("dispatcher", "ds_hash_size", 9)

modparam("dispatcher", "ds_hash_initexpire", 60)

Below is the function call based on avp(i:274)

avp_db_query("select uid from uid_did_map where accountcode = '$fU'","$avp(i:274)");

xlog("L_INFO","$rm from $fu (IP:$si:$sp) --------- UID:'$avp(i:274)-----------'\n");

ds_load_update();

if(!ds_select_dst("1","7")) {

sl_send_reply("500", "No destination available");

xlog("route[MAIN] : $rm : No destinations available for $rd");

exit;

}

I'm getting two different values for avp(i:274) {26,29} but the destination are not hashed on its base.

Please help.

Regards,

Sammy G.
