CPL script getrs loaded properly using serctl but at runtime it does not work "ERROR: t_reply: cannot send a t_reply to a message for which no T-state has been established" My config file is # $Id: ser.cfg,v 1.21.4.1 2003/11/10 15:35:15 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=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/cpl-c.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) #modparam("usrloc","db_url","mysql://root:root@localhost/ser") modparam("cpl-c","cpl_db","mysql://ser:heslo@localhost/ser") modparam("cpl-c","cpl_table","cpl") modparam("cpl-c","cpl_dtd_file","/etc/ser/cpl-06.dtd") # -- 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 > 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("iptel.org", "subscriber")) { # www_challenge("iptel.org", "0"); # break; # }; save("location"); break; }; if (method=="INVITE") { cpl_run_script("incoming","force_stateful"); }; # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("404", "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(); }; } Also here is my sample CPL XML file <?xml version="1.0" encoding="UTF-8"?> <cpl xmlns="urn:ietf:params:xml:ns:cpl" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:ietf:params:xml:ns:cpl cpl.xsd "> <subaction id="voicemail"> <location url="sip:jones@voicemail.example.com"> <proxy/> </location> </subaction> <incoming> <location url="sip:jones@jonespc.example.com"> <proxy timeout="8"> <busy> <sub ref="voicemail"/> </busy> <noanswer> <sub ref="voicemail"/> </noanswer> </proxy> </location> </incoming> </cpl> Regards Rohit ********************************************************* Disclaimer: This message (including any attachments) contains confidential information intended for a specific individual and purpose, and is protected by law.
