HI All; I have the following network: cisco ATA (valid ip) ---------------------------ser+rtpproxy---------------------------quintum GW(valid ip) 62.220.101.8 62.220.101.2 62.220.101.3 I want to pass media via ser+rtpproxy, ser can communicate with rtpproxy via unix socket sucessfully. The problem is when i call from ATA to quintum the voice path is one way??????????/ My SER.CFG and RTPPROXYLOG are as follows: # # $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/nathelper.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 > 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) { log(1, "REQUEST FOR SERVED DOMAIN------------------"); if (uri=~"^sip:3000@ 62.220.101.2"){ *********************SER VALID IP ADDRESS*********************** rewritehost("62.220.101.3");****************************QUINTUM VALID IP ADDRESS********************** force_rtp_proxy(); log(1, "-------MEDIA IS BEINGED PROXIED--------------"); forward(62.220.101.3, 5060);********************************QUINTUM VALID IP ADD************************** break; }; #we forwad to current uri now; use stateful forwarding; that # works reliably even if we forward from TCP to UDP if (!t_relay()) { sl_reply_error(); }; } ++++++++++++++++++++++++++++++++++++++++++++++++++++RTYPROXY DEBUG LOG+++++++++++++++++++++++++++++++++++++++ # rtpproxy -2f -l 62.220.101.2 -s unix:/var/run/rtpproxy.sock -t 40 rtpproxy: rtpproxy started, pid 18398 rtpproxy: new session 633554326(a)62.220.101.8, tag 3269848300 requested rtpproxy: new session on a port 35000 created, tag 3269848300 rtpproxy: pre-filling caller's address with 62.220.101.8:16384 rtpproxy: session timeout rtpproxy: RTP stats: 0 in from callee, 0 in from caller, 0 relayed, 0 dropped rtpproxy: RTCP stats: 0 in from callee, 0 in from caller, 0 relayed, 0 dropped rtpproxy: session on ports 35000/0 is cleaned up Appreciate any suggections mohammad
