I am trying to use SER in a lab environment to test a new SIP product under development. I am searching through the SER archives for help, and see that many useful responses have been offered - but none yet that addresses my simple problem -- how to get started. I have SER up and running on a Linux9 platform. Likewise SERWEB and mysql. Attached is the ser.cfg file that i am using. It is virtually unmodified from the original sample file. the setup is simple UA1 --->SER ---->UA2 We are simply trying to use the proxy to exercise the logic of registration and so on in our user agent. The UAs register ok. Then when we try to place a call from UA1 to UA2, there is an invite, followed by a 100 Trying message ( we sniff with ethereal to see this, and use our own UA debug traces as well). After a short while, we receive a 483 message - "too Many Hops" I've read through the archives and see that this can happen when there is a loop so that the hop count rises to some limit. Can we get some help with a cfg file that will allow us to accomplish this testing? I think once we get started with SER we will be able to understand better how to write modifications to the cfg script. thanks, bert -- Bert Berlin Bert Berlin Director, System Test Quintum Technologies, Inc. 71 James Way Eatontown, NJ 07724 PH 732-460-9000 ext 247 Email: bert_berlin(a)quintum.com <mailto:beert_berlin@quintum.com> # # $Id: ser.cfg,v 1.21.2.1 2003/07/30 16:46:18 andrei Exp $ # # simple quick-start config script # # ----------- global configuration parameters ------------------------ #debug=3 # debug level (cmd line: -dddddddddd) #fork=yes #log_stderror=no # (cmd line: -E) /* Uncomment these lines to enter debugging mode */ debug=7 fork=yes log_stderror=yes check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) #uncommented following line 5/3/04 port=5060 #children=4 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/nathelper.so" loadmodule "/usr/local/lib/ser/modules/textops.so" # Uncomment this if you want digest authentication # mysql.so must be loaded ! #commented the following line 5/3/04 #loadmodule "/usr/local/lib/ser/modules/auth.so" #loadmodule "/usr/local/lib/ser/modules/auth_db.so" # ----------------- setting module-specific parameters --------------- # -- usrloc params -- #modparam("usrloc", "db_mode", 0) # Uncomment this if you want to use SQL database # for persistent storage and comment the previous line #=====================> modparam("usrloc", "db_mode", 1) # -- auth params -- # Uncomment if you are using auth module # #modparam("auth_db", "calculate_ha1", yes) # # If you set "calculate_ha1" parameter to yes (which true in this config), # uncomment also the following parameter) # #modparam("auth_db", "password_column", "password") # -- rr params -- # add value to ;lr param to make some broken UAs happy modparam("rr", "enable_full_lr", 1) # ------------------------- request routing logic ------------------- # main routing logic route{ #added 5/04/04 if (method=="REGISTER") { log("REGISTER"); sl_send_reply("200","ok"); break; }; # if requests URI is numerical and starts with # zero, forward statelessly to a static destination # 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 (len_gt( max_len )) { 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 record_route(); # loose-route processing if (loose_route()) { t_relay(); break; }; # 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 (method=="REGISTER") { # Uncomment this if you want to use digest authentication # if (!www_authorize("quintum.com", "subscriber")) { # www_challenge("quintum.com", "0"); # break; # }; save("location"); break; }; # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("408", "Not Found"); break; }; }; # forward to current uri now; use stateful forwarding; that # works reliably even if we forward from TCP to UDP if (!t_relay()) { sl_reply_error(); }; }
