[Serusers] SIPP with SER
by Kostas Marneris 21 Sep '06

21 Sep '06

Hello , has anyone any experience on testing SER with SIPP ?? I've sent the following mail to sipp-users mailing list, I'm sending it also here, in case anyone has any idea or experience. ---------------------------------------------------------------------------------------------------- Hello all, I run the basic UAC senario in Host A (1.1.1.1) and the basic UAS senario in Host B (2.2.2.2). I have a SER SIP Proxy in the middle (3.3.3.3). UAC : ./sipp -sn uac -r 1 -m 1 -d 5000 -i 1.1.1.1 3.3.3.3 UAS : ./sipp -sn uas SER.cfg : I use the following hack in ser.cfg, because the default user 'service' is not actually registered in Location DB. # In INVITE handler .. ... # --- SIPP hack --- if (uri =~ "^sip:service@3.3.3.3:5060") { rewritehostport("2.2.2.2:5060"); route(1); break; }; # ----------------- # In MAIN Route Block # --------------------- Nothing changed from 'default SER behaviour' : if ((method != "REGISTER") && (method != "OPTIONS")) { log(1, " Add RR"); record_route(); }; if (loose_route()) { route(1); break; }; Where is the problem : It seems that SER doesn't recognize (in the dialog) the ACK sent by the UAC (Host A), do does not relay it to the UAS. The UAS continues to send '200 OK'... so I can't make it to have a 'full call setup simulation senario'. Call Flow : HOST A (UAC) SER HOST B (UAS) -----------> (1) INVITE <----------- (2) 100 Trying --------------> (3) INVITE <------------- (4) 180 Ringing <----------- (5) 180 Ringing <------------- (6) 200 OK <----------- (7) 200 OK -----------> (8) ACK <------------- (9) 200 OK -----------> (10) ACK .... .... The first ACK (8) from UAC to SER doesn't relayed to UAS, so UAS keeps sending '200 OK'... This ACK doesn't go through the 'loose_route()' block because SER thinks that this ACK is not in the dialog. Even if I add the following code in MAIN route block, SER insists to absorb this ACK request. ... } else if (method == "ACK") { # ACK mesgs --> route[1] log(1," * ACK -- not in the DIALOG --"); route(1); break; } else if ... Do you find something wrong in SER conf ? or do you have any idea why this happening ? ---------------------------------------------------------------------------------------------------- thanks in advance for any hint. Kostas

[Users] redundancy
by Ramin Dousti 21 Sep '06

Hi, A SIP INVITE to sip.mydoamin.com with sip.mydomain.com having two A-RR's, must be forwarded to the first IP and if that IP is unreachable then to the second IP. How can I achieve this? My first problem is that I seem to not have the list of the two IP's available to me via a configuration key-word. So I need to hardcode the IP's in my conf file. My second problem is I don't know how to iterate over these two IP's. Maybe I can use t_on_failure() and have the second IP processed in the failure_route[]. But then again, how can I distinguish between a timeout and a legitimate failure? Thank you in advance, -- Ramin

[Users] AcctSessionTime (table radacct)
by Alberto Pacifico 21 Sep '06

21 Sep '06

Hi all, I'd like to get AcctSessionTime (db radius /table radacct) with setflag(). I´ve already got the AcctStartTime and AcctStopTime. The values of AcctSessionTime that I´ve got are zero in the calls. I know that I can calculate the duration of the call using the values of AcctStartTime and AcctStopTime, but I'm using an software (CDRTool) that uses the values of AcctSessionTime to calculate the duration of the call. How can I get the value of AcctSessionTime (diferent of zero)? Thanks Alberto __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

[Serusers] Using IP address as domain
by mukesh 21 Sep '06

21 Sep '06

Hi friends, I have SER (with database support) running on my linux box. But I do not have a domain name registered for the IP of this machine but it does have a public IP (202.87.xx.xxx) address which allows me access it from outside. If I try to access (using sipsak client) a uri from local system it fails. example URIs I am trying are ... sip:mukesh@<public ip> sip:mukesh@<public ip>:5060 ...with no result :( I referred http://mit.edu/sip/sip.edu/ser.shtml to configure my ser.cfg. So the question is How can I connect to SER using IP and do I need to use "# export SIP_DOMAIN=<public ip>"? Regards Mukesh

[Users] Configurable nathelper nortpproxy string
by Jeremie Le Hen 21 Sep '06

21 Sep '06

Hi list, I have made a small patch to the nathelper module, that allows to configure the "a=nortpproxy:yes\r\n" string. Basically, as noticed in user documentation, you can add this to your configuration file, once the patch is applied and OpenSER recompiled : % modparam("nathelper", "nortpproxy_str", "a=sdpmangled:yes") I needed to do this because I have the following setup: SoftPhone1_ \____ ____NATing Proxy_______Registrar Proxy_______(outside) _/ SoftPhone2 For some reason, the registrar also uses nathelper/rtpproxy. I first used the "f" flag for force_rtp_proxy() in my NATing proxy, in order to circumvent the nortpproxy flag that the registrar proxy has set. This worked perfectly except if softphone1 tries to call softphone2. In this case my NATing proxy would replace the SDP twice. With my patch, I simply turn the nortpproxy string to something else that only my NATing proxy cares about. Please, commit it if you find it worth enough. Thank you. Best regards, -- Jeremie Le Hen < jeremie at le-hen dot org >< ttz at chchile dot org >

[Serusers] Call btn two SIP Servers
by Sharon Abraham 21 Sep '06

21 Sep '06

The prob is pretty basic. I have installed 2 SERs and have a set of users registered to either of the proxies. How can i place a call from user1 at SER1 to user2 @ SER2? This is what i've done 1. In my "domain" table (i.e. MySQL) in both SER's I have added domain entries. 2. Then into" trusted" tables of either proxies , i've added the value of the other proxy 3. Then made the entries in the ser.cfg. But when i restart ser i get this as the error [root@localhost sbin]# service ser restart Stopping ser: [ OK ] Starting ser: ERROR: bad config file (3 errors) [FAILED] My ser.cfg of one of the Proxies is as follows... can anyone help??? pls? # $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" fifo_db_url="mysql://ser:heslo@localhost/ser" # ------------------ 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/uri_db.so" loadmodule "/usr/lib/ser/modules/domain.so" loadmodule "/usr/lib/ser/modules/permissions.so" loadmodule "/usr/lib/ser/modules/xlog.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) modparam("permissions|uri_db|usrloc", "db_url", "mysql://ser:heslo@localhost/ser") modparam("permissions", "db_mode", 1) modparam("permissions", "trusted_table", "trusted") # ------------------------- 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 (method=="INVITE") { if( !allow_trusted() && !is_uri_host_local() ) { if (!proxy_authorize("","subscriber")) { proxy_challenge("","0"); break; } else if (!check_from()) { sl_send_reply("403", "Use From=ID"); break; }; consume_credentials(); }; }; # 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; }; # 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(); }; }

How is DNS resolution If I have some Openser destination and I use t_relay()? Optinos: 1 - Openser make 1 DNS query to each destination; 2 - Openser make 1 DNS query to all destination.

I copied all details during I set-up the database (with openser_mysql.sh). Unfortunately I had lost this copy and have no ideas anymore what passwords I have set-up. Which database and records do I need to delete from mysql to restart? bye Ronald
