Re: [SR-Users] dialog table entry not deleted after call if in-dialog requests are challenged

Hi I am using dialog module in Kamailio 3.1.5, and find that the dialog table entry does not get deleted after call if in-dialog requests (e.g. session timer refresh re-INVITEs in my case) are challenged. The entry will stay there and get deleted after a long time (some time out? I didn't set any dialog timeouts myself). If I remove the challenge for in-dialog requests, then the dialog entry is deleted right after the call. I use the example config script with a bit of modification for my in-dialog route: route[WITHINDLG] { xlog("L_DBG","WITHINDLG: method=$rm, callid=$ci, cseq=$cs\n"); if (has_totag() ) { # sequential request withing a dialog should # take the path determined by record-routing if (loose_route()) { # Filter out bad/faked up in-dialog requests. if ( !is_known_dlg() ) { xlog("L_WARN","WITHINDLG: NOT known dlg!! method=$rm, callid=$ci, cseq=$cs, $fu->$tu\n"); exit; } if (is_method("BYE")) { xlog("L_DBG","WITHINDLG: BYE found within Dialog \n"); setflag(FLT_ACC); # do accounting ... setflag(FLT_ACCFAILED); # ... even if the transaction fails } ########################################################## # challenge: if not CANCEL/ACK else if ( !is_method("CANCEL")&& !is_method("ACK") ) { route(AUTH); } ########################################################## xlog("L_DBG","WITHINDLG: Entering RELAY route from WITHINDLG route. \n"); route(RELAY); } else { if (is_method("SUBSCRIBE")&& uri == myself) { # in-dialog subscribe requests route(PRESENCE); exit; } if ( is_method("ACK") ) { xlog("L_DBG","WITHINDLG: ACK callid=$ci, cseq=$cs\n"); if ( t_check_trans() ) { # no loose-route, but stateful ACK; # must be an ACK after a 487 # or e.g. 404 from upstream server xlog("L_DBG","ACK being relayed\n"); t_relay(); exit; } else { # ACK without matching transaction ... ignore and discard xlog("L_DBG","ACK without matching transaction-ignore and discard\n"); exit; } } sl_send_reply("404","Not here"); } exit; } } The part that calls route(AUTH) that I added was the cause for the dialog entry not being deleted after call. Here are my dialog related settings: modparam("dialog", "enable_stats", 1) modparam("dialog", "dlg_flag", 4) modparam("dialog", "db_url", DBURL) modparam("dialog", "db_update_period", 20) # use short one to catch short dlgs (default:60) modparam("dialog", "db_mode", 1) # don't use did, so to cope with clients that don't preserve parameters # and mode 1 (fallback to 3261 matching) didn't work?? modparam("dialog", "dlg_match_mode", 2) modparam("dialog", "profiles_no_value", "inbound ; outbound") modparam("dialog", "dlg_extra_hdrs", "Hint: dialog expired\r\n") # default timeout set to max int 0x07FFFF FFFF modparam("dialog", "default_timeout", 2147483647) And I set the dialog flag (4) when receiving the initial INVITE. Any idea why? Am I using the dialog module correctly? Thanks very much!
