[SR-Users] Dispatcher does not send pings

Hi, please, could someone specify the conditions when the dispatcher module sends the INFO pings to the gateways ? modparam("dispatcher", "flags", 2) modparam("dispatcher", "dstid_avp", "$avp(s:test)") modparam("dispatcher", "dst_avp", "$avp(AVP_DST)") modparam("dispatcher", "grp_avp", "$avp(AVP_GRP)") modparam("dispatcher", "cnt_avp", "$avp(AVP_CNT)") modparam("dispatcher", "ds_ping_interval", 30) modparam("dispatcher", "ds_probing_mode", 1) modparam("dispatcher", "ds_ping_method", "INFO") modparam("dispatcher", "ds_ping_from", "sip:001122@test") And my dispatcher.list is: 1 sip:IP1:5060 1 sip:IP2:5060 Am I missing something? I dumped all the communication and the kamailio(dispatcher) does not send anything.. Thanks, Mino
