[Serusers] ser-0.9.6: modules/postgres bugreport & patch

by Alexandre Snarskii

Hi! I'm running ser-0.9.6, on FreeBSD 6.1-stable, database backend is postgresql version 8.1.3. Today I got errors in logfiles, saying: messages.2.bz2:May 29 14:35:03 <XXX> /usr/local/sbin/ser[51448]: ERROR:avpops:dbrow2avp: dbrow contains NULL fields The similar problem reported in: http://lists.iptel.org/pipermail/serusers/2005-May/019681.html with much more detailed description of error, database contents and config samples. Patch is trivial, and looks more like a fix to copy'n'paste error: in mysql/val.c function str2val states: if (!_s) { memset(_v, 0, sizeof(db_val_t)); VAL_TYPE(_v) = _t; VAL_NULL(_v) = 1; return 0; } VAL_NULL(_v) = 0; and the last line mentions that 'well, that's value is not NULL'. In postgresql/db_val.c, line 182, function str2valp, the same statement is the: if (!_s) { DLOG("str2valp", "got a null value"); VAL_TYPE(_v) = _t; VAL_NULL(_v) = 1; return 0; } without explicit notification that this is not-NULL value. More than, nowhere else in this function VAL_NULL(_v) not set to 0. So, if a value _v.val contained anyting but 0 at the function start, resulting value will be threated as NULL despite the fact, that _s is NOT NULL. Patch is obvious, just add VAL_NULL(_v)=0; after cited block (line 188) and everyting will be ok. At least for me it's ok for some hours :)

[Serusers] SER Nokia CANCEL Problem

by Abdul Qadir

Hi , I tried to call from one nokia sip (E61 and other models )phone to another nokia sip phone. The call works fine. The problem comes only when I call from Phone A to Phone B and then immediately cancel the call(from Phone A). The Phone A will hangup the call as it sent CANCEL but the SER will ignore this CANCEL and still send INVITE to Phone B resulting in a ghost call situation. I tried to capture a log of message and found that Phone A "CANCEL" message is received on SER even before any provisional response from Phone B. Therefor SER doesnot relay this CANCEL request to Phone B. I even checked RFC which clearly says that UAC should not send CANCEL untill it receives any provisional response. I talked to Nokia expert and they said the 100 Trying message from your server is considered as provisional response, therefor behaviour of client is absolutely correct. Is there any way I can stop 100 Trying message and still run statefull SER, so that I can verify what nokia said. Any ideas suggestions are welcome. Thanking you all in advance.

[Users] Re: 200 ok not cought in ONREPLY

by Dan-Cristian Bogos

Guys, thanks to your support (both Bogdan and Daniel), I found out that there was nothing wrong with the server and t_onreply handling, but the INVITE was taking another routing three than the one I was checking and therefore never hit the t_on_reply section I wanted. This being said, I consider this issue resolved. Cheers, Dan

[Users] AVP management

by Ovidiu Sas

Hi all, There are modules that are using default values for AVPs. What will happen if another module is reusing the same AVP? Or if the AVP is redefined inside the script? Is this completely orthogonal? Should I worry about this while using AVPs? Regards, Ovidiu Sas

[Users] understanding SEMS

by Victor Gamov

hi guys! can somebody explain me how SEMS works with SER/OpenSER. As I conceive proxy sends requests to SEMS via unix socket. Then SEMS needs constructs reply or new request and ask proxy to send it. But where reply come to proxy? into onreply_route[0] block? is it possible to use t_on_reply() function when initial request writing to SEMS to ask proxy to use specific onreply_route[] block? Thanks for advise! -- CU, Victor Gamov

[Users] provisional_reply_timer

by Klaus Darilion

Hi! i wonder if there is a timer which controls the timeout for provisional replies. E.g. I want to cancel an INVITE and retry another gateway if the gateway does not respond with 100 (or 180) in a certain time. regards klaus -- Klaus Darilion nic.at

[Serusers] Configuring SER to work as SIP proxy

by dzus＠mat.uni.torun.pl

All, I am trying to configure SER to work as SIP proxy (not registar and not redirect). I tried to modify simple ser.cfg which comes with SER by adding one line in route[0]: rewritehostport("192.168.1.2:5060"); This unfortunately doesn't work. The message to my SIP server 192.168.1.2 are indeed forwarded. But message comming back from 192.168.1.2 are looped by my SIP proxy (192.168.1.3) back to SIP server (192.168.1.2). Can someone help me? Or send a working cfg for SIP proxy, I cannot find any. This is my complete ser.cfg: # # $Id: ser.cfg,v 1.25.2.1 2005/02/18 14:30:44 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 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 "//lib/ser/modules/mysql.so" loadmodule "//lib/ser/modules/sl.so" loadmodule "//lib/ser/modules/tm.so" loadmodule "//lib/ser/modules/rr.so" loadmodule "//lib/ser/modules/maxfwd.so" loadmodule "//lib/ser/modules/usrloc.so" loadmodule "//lib/ser/modules/registrar.so" loadmodule "//lib/ser/modules/textops.so" # Uncomment this if you want digest authentication # mysql.so must be loaded ! #loadmodule "//lib/ser/modules/auth.so" #loadmodule "//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 >= 2048 ) { 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 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") { # Uncomment this if you want to use digest authentication # if (!www_authorize("iptel.org", "subscriber")) { # www_challenge("iptel.org", "0"); # break; # }; 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] { # send it out now; use stateful forwarding as it works reliably # even for UDP2TCP # Dzus rewritehostport("192.168.1.2:5060"); if (!t_relay()) { sl_reply_error(); }; } ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

[Users] 473 Filtered destination?

by Tobias Lindgren

Hi, recently moved from SER > OpenSER 1.2.0, but after some time when the server is running OpenSER starts to respond with: "SIP/2.0 473 Filtered destination (473/TM)." to my INVITEs. I don't have any blacklists/accesslist configured (the config is from SER which doesn't support that), why am I seeing this problem? Br, /Tobias
