[Serusers] RTPProxy Problem !

Hi, I installed "Ser-0.8.14" + "nathelper" + "rtpproxy" in RedHat 9.0, and add "./rtpproxy" in startup script, when i tried both sipsoftphone in the internet behind NAT that can connect but "no voice" and auto hang-up, but when both sipsoftphone in local network that no problem ! Which port range i need release for rtpproxy in the firewall ? my ser.cfg config as below : # ----------- 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 #debug=4 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 ---------------------------------- 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/nathelper.so" # Uncomment this if you want digest authentication # mysql.so must be loaded ! #loadmodule "/usr/local/lib/ser/modules/dbtext.so" #loadmodule "/usr/local/lib/ser/modules/auth.so" #loadmodule "/usr/local/lib/ser/modules/auth_db.so" #loadmodule "/usr/local/lib/ser/modules/mysql.so" # ----------------- setting module-specific parameters --------------- # -- usrloc params -- modparam("usrloc", "db_mode", 0) #modparam("auth_db", "db_url", "db:/var/dbtext") #modparam("auth_db", "user_column", "user") #modparam("auth_db", "domain_column", "domain") #modparam("auth_db", "password_column", "password") #modparam("auth_db", "calculate_ha1", 1) #modparam("auth_db", "password_column_2", "ha1_2") modparam("registrar", "nat_flag", 6) modparam("nathelper", "natping_interval", 30) # Ping interval 30 s modparam("nathelper", "ping_nated_only", 1) # Ping only clients behind NAT modparam("nathelper", "rtpproxy_sock","/var/run/rtpproxy.sock") # -- 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 #define NAT_UAC_TEST_C_1918 0x01 /* * test for occurences of RFC1918 addresses in Contact * header field */ #define NAT_UAC_TEST_RCVD 0x02 /* * test if source address of signaling is different from * address advertised in Via */ #define NAT_UAC_TEST_V_1918 0x04 /* * test for occurences of RFC1918 addresses in SDP body */ #define NAT_UAC_TEST_S_1918 0x08 /* * test for occurences of RFC1918 addresses top Via */ 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; }; if (nat_uac_test("3")) { append_hf("Alex-hint: NAThelper\r\n"); fix_nated_contact(); # Rewrite contact with source IP of signalling if (method == "REGISTER" || ! search("^Record-Route:")) { #if (www_authorize("iptel.org", "subscriber")) { # www_challenge("iptel.org", "1"); # }; if (method == "INVITE") { append_hf("Alex-hint: SDP rewritten\r\n"); fix_nated_sdp("3"); # Add direction=active to SDP }; log("LOG: Someone trying to register from private IP, rewriting\n"); force_rport(); # Add rport parameter to topmost Via setflag(6); # Mark as NATed }; }; if (!method=="REGISTER") record_route(); # 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") { 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] { # !!
