Re: [Serusers] UDP to TCP using SER (as conversion purpose), need ser.cfg example

hi i have large voip udp packets over internet problems and i need the transfer medium to be tcp. below is what i had in mind. SIPp_client A (TCP out) -> (listen TCP) SER 1 (UDP out) --> Soft-switch (UDP in /out only) --> (to) ring Client B (listen UDP) Client A and Client B registers to above Soft-switch. All the above are individual servers (Linux CentOS based) i need help in a (conversion) ser.cfg. Can anyone post a sample ?? below is my ser.cfg (tried using t_relay_to_udp(), rewritehost(), rewritehostport(), forward functions BUT none seems to work the way i want it to) SER 1 == 192.168.10.203 Softswitch == 192.168.10.251 Client A == 192.168.10.221 or .236 (SIPp client-registered to soft-switch successfully) Client B == 192.168.x.x (registered to soft-switch successfully) Thanks shengmai shengmai_goh(a)innomedia.com.sg # # $Id: ser.cfg,v 1.25.2.1 2005/02/18 14:30:44 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 fork=no log_stderror=yes */ check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) 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/textops.so" loadmodule "/usr/local/lib/ser/modules/print.so" loadmodule "/usr/local/lib/ser/modules/uri.so" # Uncomment this if you want digest authentication # mysql.so must be loaded ! #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", 2) # -- 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{ # 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 >= 2048 ) { 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=="REGISTER") record_route(); #if (method == "INVITE") { # if (uri =~ "sip:*@*"){ # log(1, "Forwarding to Vsp12K\n"); # rewritehostport("192.168.10.204:5060"); # t_relay(); # break; # } #}; if (uri =~ "sip:*@*"){ #log(1, "Forwarding to Vsp12K\n"); #rewritehostport("192.168.10.204:5060"); if (uri =~ "sip:*@192.168.10.203"){ rewritehostport("192.168.10.251:5060"); } t_relay_to_udp("192.168.10.251", "5060"); #t_relay(); break; }; # subsequent messages withing a dialog should take the # path determined by record-routing if (loose_route()) { # mark routing logic in request append_hf("P-hint: rr-enforced\r\n"); route(1); break; }; if (!uri==myself) { # mark routing logic in request append_hf("P-hint: outbound\r\n"); route(1); 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("iptel.org", "subscriber")) { # www_challenge("iptel.org", "0"); # break; # }; save("location"); break; }; lookup("aliases"); if (!uri==myself) { append_hf("P-hint: outbound alias\r\n"); route(1); break; }; # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("404", "Not Found"); break; }; }; append_hf("P-hint: usrloc applied\r\n"); route(1); } route[1] { # ----------------------------------------------------------------- # Pass on stuff going to PSTN to Asterisk # ----------------------------------------------------------------- #if (uri=~"^sip:*@.*") { # rewritehostport ("*192.168.10.204:5060"); # if (!t_relay()) { # # sl_send_reply ("403", "prout"); # sl_reply_error(); # }; # break; #}; rewritehostport("192.168.10.204:5060"); # send it out now; use stateful forwarding as it works reliably # even for UDP2TCP if (!t_relay()) { sl_reply_error(); }; break; } _______________________________________________ Serusers mailing list Serusers(a)lists.iptel.org http://lists.iptel.org/mailman/listinfo/serusers
