confirm 83b7fb1612811c64f85f47a6046dd84dea286d15 Dear........ I want to networking among three SIP servers. But now I am trying using two servers likes three servers. That is, - source : computer A ip address ; 192.168.178.194 sipuri : sip:mj@192.168.178.194 - via : computer B ip address : 192.168.178.193 sipuri : sip:hj@192.168.178.193 - destination : computer A ip address :192.168.178.194 sipuri : sip:mj@192.168.178.194 And I am using sipp to test (I modified the "via" part based on original uac module). ===================================================== << computer B's test.cfg >> # # $Id: welcome.cfg,v 1.3 2003/11/03 13:03:56 janakj Exp $ # # welcome message for new subscribers; based on exec # # ----------- global configuration parameters ------------------------ debug=3 # debug level (cmd line: -dddddddddd) # must be yes since REGISTER processing causes an INVITE to be sent, # which needs to be processed by another process fork=yes children=4 alias="kims.myserver.sampro.cse" alias="myserver.sampro.cse" alias="192.168.178.193" # debugging log_stderror=yes # (cmd line: -E) mhomed=yes fifo="/tmp/ser_fifo" # ------------------ module loading ---------------------------------- # Uncomment this if you want to use SQL database 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/exec.so" # ----------------- setting module-specific parameters --------------- # -- usrloc params -- modparam("usrloc", "db_mode", 2) #modparam("usrloc", "db_url", "mysql://ser:heslo@192.168.2.16/ser" ) modparam("usrloc", "db_url", "mysql://root:heslo@localhost/ser") # ------------------------- request routing logic ------------------- # main routing logic route{ log(1, "\n\n"); log(1, "START!!!\n"); # initial sanity checks -- messages with # max_forwards==0, or excessively long requests if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); break; }; if (msg:len>=204822) { sl_send_reply("513", "Message too big"); break; }; # we record-route all messages -- to make sure that # subsequent messages will go through our proxy; that's # particularly good if upstream and downstream entities # use different transport protocol # if (method=="INVITE") record_route(); # 1=loose routing if(method=="INVITE"){ log(1, "receive INVITE\n"); record_route(); sl_send_reply("200", "ok"); }; # loose-route processing if (loose_route()) { t_relay(); break; }; # if(method=="ACK"){ # log(1, "receive ACK\n"); # }; log(1, "record-route processing completed\n"); # if the request is for other domain use UsrLoc # (in case, it does not work, use the following command # with proper names and addresses in it) # if (uri==myself) { # # if(uri=="sip:mijin@sam.cse"){ # forward(192.168.178.194, 5060); # }; if (uri=~"sip:192.168.178.193"){ if (method=="REGISTER") { log(1, "receive REGISTER\n"); # save location before initiating welcome save("location"); log(1, "save &#236;&#8222;±&#234;³&#181;\n"); record_route(); sl_send_reply("200", "ok"); # welcome message log(1, "route3&#236;œ¼&#235;¡œ &#236;&#65533;´&#235;&#65533;™ \n"); route(3); break; }; # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("404", "Not Found"); log(1, "Usrloc DB&#236;&#8212;&#65533;&#236;&#8222;œ &#236;°¾ &#236;&#65533;&#8222; &#236;&#710;&#732; &#236;&#8212;†&#236;&#65533;Œ \n"); break; }; }; if(method=="BYE"){ log(1, "receive BYE\n"); record_route(); sl_send_reply("200", "ok"); break; }; t_relay(); } # welcome message -- if a REGISTER succeeded, look if it is the first-time; # if so, initiate click-to-dial transaction to set up call to an announcement # server; edit the config values first to make it work route[3] { if (!exec_msg(' # config: # --announcement server URI ANS="sip:hjkim@myserver.sampro.cse" # --SIP domain # DOMAIN="192.168.178.193" DOMAIN="192.168.178.193" # ctd CTD=${HOME}/sip_router/examples/ctd.sh # ------------------------------------ # check if first time ...

What can I do for doing what I want ??? Is there any problem in my test.cfg file ????? I would like to know in detail . please tell me what to do............................... sipp module can't support that???? And Please tell me about forward funtion. I don't know whether I understand forward function usage well....... sorry ............ Song _________________________________________________________________ 고.. 감.. 도.. 사.. 랑.. 만.. 들.. 기..
