[Serusers] Callee is behind NAT, start the mediaproxy session

by Doug Eubanks

What is the easiest way if it is possible to determine if the person being calling is behind NAT and then start the media_proxy session. I have worked out that if the caller is behind NAT, start the media session, and it works great. But if the caller is not behind NAT, and the callee is, the phone rings and when you pick it up, no sound flows in either direction. Thanks, Doug

[Serusers] SER Authentication Prob

by Ashling O'Driscoll

Hi all, Hope somebody can help-I really am stumped as to why this won't work and would really appreciate if someone could shed some light on the problem.... I currently have SER set up and clients are registering successfully. However I want clients to authenticate before they can register. Howevere when I uncomment the relevant lines in the ser.cfg file, my clients can't register. The only thing I can think of is that SER is behind NAT and my clients may/may not be behind NAT....I have included my ser.cfg file below...I have spent along time trying to understand why this is happening so any help will be appreciated! Thanks, Aisling. # # $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" alias=84.203.148.14 # ------------------ module loading ---------------------------------- # Uncomment this if you want to use SQL database #loadmodule "/usr/lib/ser/modules/mysql.so" loadmodule "/usr/lib/ser/modules/sl.so" loadmodule "/usr/lib/ser/modules/tm.so" loadmodule "/usr/lib/ser/modules/rr.so" loadmodule "/usr/lib/ser/modules/maxfwd.so" loadmodule "/usr/lib/ser/modules/usrloc.so" loadmodule "/usr/lib/ser/modules/registrar.so" loadmodule "/usr/lib/ser/modules/nathelper.so" #loadmodule "/usr/lib/ser/modules/mediaproxy.so" loadmodule "/usr/lib/ser/modules/textops.so" #loadmodule "/usr/lib/ser/modules/maxfwd.so" # Uncomment this if you want digest authentication # mysql.so must be loaded ! #loadmodule "/usr/lib/ser/modules/auth.so" #loadmodule "/usr/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) #!!Nathelper #modparam("registrar","nat_flag",6) #modparam("nathelper","natping_interval",30) #Ping intervals 30 seconds #modparam("nathelper","ping_nated_only",1) #Ping only clinets behind NAT # -------------------------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; }; #############Aisling Insert################ # #!Nat Insert # #the below line tests if the IP of the received packet is different from the IP in the via header and also # #sees if the IP address in the contact header is private # if (nat_uac_test("3")){ # if (method == "REGISTER" || ! search("^Record-Route:")){ # log("Log: Someone trying to register from private IP,rewriting\n"); # # fixed_nated_contact(); #Rewrite contact with source IP # if (method == "INVITE"){ # fix_nated_sdp("1"); #Add direction=active to SDP # }; # force_rport(); # Add rport parameter to topmost Via # setflag(6); # Mark as Nated # }; # }; ###################End##################### # 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(); # 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("84.203.148.14", "subscriber")) { # www_challenge("84.203.148.14", "0"); # break; # }; save("location"); break; }; # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("404", "Not Found"); break; }; }; #inserted by klaus if (method == "INVITE"){ record_route(); force_rtp_proxy(); /* set up reply processing*/ t_on_reply("1"); }; # 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(); }; } #insert by klaus onreply_route[1]{ if (status=~"[12][0-9][0-9]") force_rtp_proxy(); } #route[1] #{ #if client or server know to be behind NAT, enable relay # if (isflagset(6)){ # force_rtp_proxy(); # }; # # #NAT processing of replies; apply to all transaction (for example, # #reinvites from public to private UA are hard to identify as # #Nated at the moment of request processing); look at replies # t_on_reply("1"); # # #send it out now; use stateful forwarding as it works reliably # #even for UDP2TCP # if(!t_relay()){ # sl_reply_error(); # }; #} #!!NatHelper #onreply_route[1]{ #Nated Transaction??

[Serusers] permissions module BUG??

by Java Rockx

Hello All. I'm trying to get allow_trusted() to work but this is output to my syslog. Jan 24 14:42:55 sip01 /usr/local/sbin/ser[3308]: use_table(): Invalid parameter value Jan 24 14:42:55 sip01 /usr/local/sbin/ser[3308]: allow_trusted(): Error while trying to use trusted table My ser.cfg looks like this: modparam("permissions", "db_url", "mysql://ser:heslo@localhost/ser") modparam("permissions", "db_mode", 0) modparam("permissions", "trusted_table", "trusted") route { if (!allow_trusted()) { blah blah }; } Is this a bug with ser-0.9 from cvs??

Re: [Serusers] Ser and Asterisk Integrated

by Felipe Martins

Hi Lode, First, thanks for the hand, I've begun with ser, and I managed to get it working fine ... but i'm still working on the routing logic routines to get closer to it, i've found a lot of information at voiwiki.org, in fact, its been a long time i didn't see so documented site. The problem is that some docs are a kind of advanced, this could be due to my total inexperience at VoIP. I've first got Asterisk because, I need it to pass username and password again to another server, it's not possible in SER. Thanks for the Live Cd and the HD erasing Warning, i'm gonna check it out to see if it applys to my needs, and I'll let you know, for sure as soon as I can get it working.

As i'm very new to VoIP and mainly to Asterisk and SER, i'm reading all the documentation I've found but I couldn't find any dox telling how to integrate them, with example config files and some graphs or something.

[Serusers] *67 and is_user_in()

by Java Rockx

Hi All. How would I properly check a user's group membership (ie, in the MySQL grp table) when the user has dialed *67 to enable caller ID blocking? The problem is the "From" header is then "anonymous" which won't work with if (is_user_in("From", "free-pstn")) { blah blah }; Regards, Paul __________________________________ Do you Yahoo!?

[Serusers] RPID question

by Java Rockx

Hi All. It seems that append_rpid_hf() in ser-0.9 will not insert the Remote-Party-ID header unless proxy_authorize() is called first. Is this normal behaviour?
