[Serusers] Call forwarding / [Sems] (no subject)
by Raphael Coeffic 10 Mar '04

10 Mar '04

Hello *, Does anybody have some ideas realizing such a scenario? I don't think using Cisco SPS and SIP at the same time is such a good idea. I'm not sure using Cisco SPS at all would be a good idea, as it is a typical vendor pitfall. Our IVR is in a to early state to be used in a production system. Maybe in 6 month... -Raphael. ----- Original Message ----- From: <dzheng(a)cogeco.ca> To: "Raphael Coeffic" <rco(a)iptel.org> Sent: Wednesday, March 10, 2004 8:49 PM Subject: Re: [Sems] (no subject) > Raphael: > > Thank you for quick response.

[Serusers] SER and SIP headers
by Curro 10 Mar '04

10 Mar '04

Hello I would like to ask the list some questions about headers. I've been reading the list and textops module, but I haven't found how to do this. Imagine a scenario with 2 SER proxies. The first proxy adds a header like: Path: <....> 1 )How can the second proxy add a parameter to this header (and not a new header)? The result that I'm looking for is something like: Path: <....>,<....> 2 ) I know that SER can check whether a header is present(is_present_hf()), but is it possible to extract the information of a header and use it? I can't use search() function, because I don't know the information, just the header name. I need to read some parameters from a header of a SIP message to construct a new header. Thank you very much for your time Regards, Curro

by Laurent BURGY 10 Mar '04

10 Mar '04

Hi, I've a problem that has already been submitted but i can't find the answer, it concerns the pa module .. I'm using Windows Messenger 4.7 but the users seem to be away (even if they're not connected) whatever i do.. In the config file, i've added these lines if(method=="SUBSCRIBE") { if(!t_newtran()){ sl_reply_error(); break; }; if(!handle_subscription("registrar")){ sl_reply_error(); break; }; break; }; I've found these lines in an archive but i don't know if i'm right... thx, Laurent

[Serusers] rtpproxy/nathelper configuration issues. i think.
by Eric C. Snowdeal III 10 Mar '04

10 Mar '04

i've been getting my sea legs with SER and am having trouble getting rtpproxy to nathelper to work correctly with my setup. since everything works fine if i test the scenario with a freeworld dialup account, i'm assuming that my problems are solely due to the vastness of my ignorance on how to configure SER correctly. i have three x-lite clients [ one is running on windows 2000 not sure of the build number, but it's the latest download from the website; the other two clients are both build 1101 on mac 10.2.3. SER running on a rh9 box on a public IP with rtpproxy. i installed ser-0.8.12-0.i386.rpm which i downloaded from the ftp server. the x-lite clients are sitting behind a linksys befw11s4 nat router. i can run SER without nathelper/rtpproxy and make and receive calls to clients outside the my network. however, things fall apart quickly when i try to run more than one client behind the nat [ lost audio, timeouts etc] which i presume is what nathelper is supposed to deal with. if try to run to use nathelper, i can't make a call from a one client to another client behind the lan. the calls won't go through - they simply timeout. i downloaded and compiled rtpproxy which i obtained from the portaone website and simply started it from the command line. i can't figure out how to get any debugging messages from rtpproxy, but i can see that the process exists and /var/run/rtpproxy.sock is created. i altered ser.cfg using the template i found in the ser-0.8.12_src tarball [ /modules/nathelper/nathelper.cfg ]. see my config below [1]. i understand that things have changed quite a bit in the CVS head, but i tried to compile and install the latest CVS version, but i ran into a host of config errors using the nathelper.cfg supplied, so i decided to backtrack, gather my wits, and stick with the released version. the x-lite clients appear to register appropriately with the server [2 - public ip addresses have been changed to protect the innocent]. to my untrained eye, these messages look the same as what i see when i test things using freeworld dialup accounts and i can make a call to another client on the same lan segment - i.e. the internal IP addresses are being sent. the location database also shows that the internal IP addresses are being used [3], but i don't know if this is what i want or not. oh. i'm also using my.public.box - a FQDN - as in the x-lite fields where it asks for "Domain/Realm", "SIP Proxy" and "Out Bound Proxy". so anyone care to grab me by the lapels and point out what i'm obviously doing wrong :-) [1] # # $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/lib/ser/modules/mysql.so" loadmodule "/usr/lib/ser/modules/nathelper.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" # 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) alias="my.public.box" # ------------------------- 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; }; # compulsory processing of Route header fields and adding RR loose_route(); /* registration (uses rewritten contacts) */ if (method=="REGISTER") { save("location"); break; }; if (method=="INVITE") { record_route(); if (isflagset(1)) { # ATA ?
