Sorry for the late reply....
the dispatcher is set as follows:
# ----- dispatcher params -----
modparam("dispatcher", "list_file", DS_LIST)
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)")
modparam("dispatcher", "ds_hash_size", 9)
modparam("dispatcher", "dstid_avp", "$avp(dsdstid)")
modparam("dispatcher", "ds_ping_latency_stats", 1)
I think it is correct, though what I wish is to set dispatcher on Load
Balancing mode.
This is my dispatcher.list :
1 sip:10.19.XXX.YYY:5060 0 1 duid=sipgw01;maxload=100
1 sip:10.19.XXX.YYY:5060 0 2 duid=sipgw02;maxload=100
1 sip:10.19.XXX.YYY:5060 0 3 duid=sipgw03;maxload=100
1 sip:10.19.XXX.YYY:5060 0 4 duid=sipgw04;maxload=100
This is my dispatch routes:
# Dispatch requests
route[DISPATCH] {
if(!ds_select_dst("1", "10","4"))
{
xlog("L_INFO","no destination selected from dispatcher
list!");
send_reply("404", "No destination");
exit;
}
xlog("L_INFO","going to <$ru> via <$du>\n");
t_on_failure("RTF_DISPATCH");
route(RELAY);
exit;
}
Any clue?
