[Serusers] Can't see BYE anywhere

Hi, i'm trying to forward the calls to deltathree's netfork but the problem is that i can CANCEL the call but if the call has started i can't send BYE to the server. SER is not recording any BYE messages and a simple call from 10-20 sec. is recorder as 100-110 sec.'s on deltathree servers. Here is my config: debug=3 fork=yes log_stderror=no listen=192.168.0.2 #listen=127.0.0.1 # hostname matching an alias will satisfy the condition uri==myself". alias=intranet.com.mk alias=192.168.0.2 # dns - Uses dns to check if it is necessary to add a "received=" field # to a via. Default is no. # rev_dns - Same as dns but use reverse DNS. dns=no rev_dns=no port=5060 children=4 # check_via - Turn on or off Via host checking when forwarding replies. # Default is no. arcane. looks for discrepancy between name and # ip address when forwarding replies. check_via=yes # syn_branch - Shall the server use stateful synonym branches? It is # faster but not reboot-safe. Default is yes. syn_branch=yes # memlog - Debugging level for final memory statistics report. Default # is L_DBG -- memory statistics are dumped only if debug is set high. memlog=3 # sip_warning - Should replies include extensive warnings? By default # yes, it is good for trouble-shooting. sip_warning=yes # fifo - FIFO special file pathname fifo="/tmp/ser_fifo" # server_signature - Should locally-generated messages include server's # signature? By default yes, it is good for trouble-shooting. server_signature=yes # reply_to_via - A hint to reply modules whether they should send reply # to IP advertised in Via. Turned off by default, which means that # replies are sent to IP address from which requests came. reply_to_via=no # user | uid - uid to be used by the server. 99 = nobody. uid="nobody" # group | gid - gid to be used by the server. 99 = nobody. gid="nobody" # mhomed -- enable calculation of outbound interface; useful on # multihomed servers. mhomed=0 # ------------- external module loading loadmodule "/usr/local/lib/ser/modules/mysql.so" loadmodule "/usr/local/lib/ser/modules/sl.so" loadmodule "/usr/local/lib/ser/modules/tm.so" loadmodule "/usr/local/lib/ser/modules/rr.so" loadmodule "/usr/local/lib/ser/modules/maxfwd.so" loadmodule "/usr/local/lib/ser/modules/usrloc.so" loadmodule "/usr/local/lib/ser/modules/registrar.so" loadmodule "/usr/local/lib/ser/modules/auth.so" loadmodule "/usr/local/lib/ser/modules/auth_db.so" loadmodule "/usr/local/lib/ser/modules/acc.so" loadmodule "/usr/local/lib/ser/modules/exec.so" loadmodule "/usr/local/lib/ser/modules/group.so" loadmodule "/usr/local/lib/ser/modules/print.so" loadmodule "/usr/local/lib/ser/modules/textops.so" loadmodule "/usr/local/lib/ser/modules/uri.so" # ------------- tm parameters modparam("tm", "fr_timer", 12) modparam("tm", "fr_inv_timer", 24) # ------------- rr parameters modparam("rr", "enable_full_lr", 1) modparam("rr", "append_fromtag", 1) # ------------- accounting parameters modparam("acc", "db_url", "sql://ser:heslo@localhost/ser") modparam("acc", "db_flag", 1) modparam("acc", "db_missed_flag", 3) modparam("acc", "report_ack", 0) modparam("acc", "report_cancels", 1) modparam("acc", "early_media", 1) # Account failed transactions modparam("acc", "failed_transactions", 1) modparam("acc", "log_fmt", "miocfst") # ------------- usrloc parameters modparam("usrloc", "db_mode", 2) modparam("usrloc", "timer_interval", 10) modparam("usrloc", "db_url", "sql://ser:heslo@localhost/ser") # ------------- auth parameters modparam("auth_db", "db_url", "sql://ser:heslo@localhost/ser") modparam("auth_db", "calculate_ha1", yes) modparam("auth_db", "password_column", "password") # ------------- routing logic route{ # filter too old messages if (!mf_process_maxfwd_header("10")) { log("LOG: Too many hops\n"); sl_send_reply("483","Too Many Hops"); break; }; if (msg:len > max_len) { sl_send_reply("513", "Message too large"); break; }; /* ********* RR ********************************** */ /* Do strict routing if route headers present */ loose_route(); /* record-route INVITEs -- all subsequent requests must visit us */ if (method=="INVITE") { record_route(); } else if (method=="REGISTER") { log("here is a register"); save("location"); break; }; # now check if it really is a PSTN destination which should be handled # by our gateway; if not, and the request is an invitation, drop it -- # we cannot terminate it in PSTN; relay non-INVITE requests -- it may # be for example BYEs sent by gateway to call originator if (!uri=~"sip:9[0-9]*@.*") { if (method=="INVITE") { sl_send_reply("403", "Call cannot be served here"); setflag(1); } else if(method=="BYE") { setflag(1); t_relay(); } else if(method=="CANCEL") { setflag(1); t_relay(); } else { t_relay(); }; break; }; # account completed transactions via syslog setflag(1); strip(1); rewritehostport("natrelay.deltathree.com:5060"); # forward the request now if (!t_relay()) { sl_reply_error(); break; }; }
