[SR-Users] Dispatcher caches IP

Hello. I try to integrate dispathcer module (with db table dispatcher) to my Kamailio server. I have problem with changing IP at db table, but when I calling - call goes to old IP that alread deleted from db. I tested my table with query that selects destination address from table, and it replyes to me correct address. I use round-robin ("4") algorythm 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", "$avp(i:271)") modparam("dispatcher", "grp_avp", "$avp(i:272)") modparam("dispatcher", "cnt_avp", "$avp(i:273)") modparam("dispatcher", "ds_ping_from", "sip:proxy@10.0.0.2") 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") How to disable this cache?
