[Serusers] ser-0.9.6: modules/postgres bugreport & patch
by Alexandre Snarskii 13 Oct '08

13 Oct '08

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 07 May '08

07 May '08

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.

Dear all I have a big problem with openxcap. I don't get it work :( As I saw on their webpage, this mailing list can be posted for this concern as well.

[Users] Re: 200 ok not cought in ONREPLY
by Dan-Cristian Bogos 19 Oct '07

19 Oct '07

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

[OpenSER-Users] Usrloc lookup ad parallel forking
by Edoardo Serra 15 Oct '07

15 Oct '07

Hi all, I have OpenSER (1.2.2) acting as registrar server. If the same user hase more than one AOR I'd like to do parallel forking and send the INVITE to every contact I have for that user. At the moment my configuration file looks like: if (!lookup("location")) { sl_send_reply("404", "Not Found"); exit; }; t_on_reply("1"); if (!t_relay()) { sl_reply_error(); }; exit; but it rely only to the AOR with the highest q value It should be a common situation but I cannot find any doc about it. Tnx in advance Regards Edoardo Serra

[OpenSER-Users] logging problem
by Klaus Darilion 10 Oct '07

10 Oct '07

Hi! I just compiled a fresh openser-1.2 (no installation - only "make all" and running it as non-privileged user from the source directory). Everything works fine except that I can not see L_DEBUG messages in syslog (debug=3 causes the same output in syslog as debug=4) and I'm stuck in finding the problem. When starting openser with -D -E -dd I see DEBUG messages too. thanks Klaus

Looking at libxmlrpc_clent.so.7 nm -B libxmlrpc_client.so.7 | grep HTThroughLine returns U HTThroughLine If anyone can shed some light on this it would be very greatly apprecated. regards -kim --

[OpenSER-Users] SRV load-balancing not balancing evenly?
by Tim Madorma 09 Oct '07

09 Oct '07

Hi, The OpenSER is performing an SRV lookup which returns the following record info: ;; QUESTION SECTION: ;_sip._udp.aimcidfilter.com. IN SRV ;; ANSWER SECTION: _sip._udp.aimcidfilter.com. 180 IN SRV 1 50 5061 spinner.eng.rr.com. _sip._udp.aimcidfilter.com. 180 IN SRV 1 50 5061 bart.eng.rr.com. _sip._udp.aimcidfilter.com. 180 IN SRV 2 50 5061 homer.eng.rr.com. _sip._udp.aimcidfilter.com. 180 IN SRV 2 50 5061 crunch.eng.rr.com. As you can see, the weighting for the two priority "1" endpoints is 50/50 which indicates that the load should be distributed evenly between them. But when I run my test, it consistently sends 75% to spinner.eng.rr.com and 25% to bart.eng.rr.com. Any ideas? ----------- some config info. debug=5 # debug level (cmd line: -dddddddddd) fork=yes log_stderror=no # (cmd line: -E) maxbuffer=1048576 check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) #reply_to_via=1 children=4 log_facility=LOG_LOCAL4 dns_use_search_list=no dns_servers_no=2 # user="sipproxy" group="sipproxy" #disable_dns_blacklist=yes # FOR TESTING ONLY #dns_try_ipv6=no # FOR TESTING ONLY listen=udp:65.185.232.62:5060 alias=65.185.233.104:5060 # LOAD OpenSER MODULES mpath="/sw/lib/openser/modules/" loadmodule "sl.so" loadmodule "tm.so" loadmodule "rr.so" loadmodule "maxfwd.so" loadmodule "usrloc.so" loadmodule "registrar.so" loadmodule "textops.so" loadmodule "acc.so" loadmodule "mi_fifo.so" loadmodule "xlog.so" # ----------------- setting module-specific parameters --------------- # -- usrloc params -- modparam("usrloc", "db_mode", 0) # -- rr params -- # add value to ;lr param to make some broken UAs happy modparam("rr", "enable_full_lr", 1) # ------------------------- request routing logic ------------------- modparam("acc", "log_level", 2) modparam("acc", "log_flag", 1) modparam("acc","report_cancels", 1) modparam("acc","failed_transaction_flag", 1) modparam("acc","log_extra", "req_uri=$rU") modparam("tm", "fr_timer", 5) modparam("tm","fr_inv_timer",5) modparam("mi_fifo", "fifo_name", "/tmp/openser_fifo")

[OpenSER-Users] problem with 407 return code
by tloginbr-openser＠yahoo.com.br 09 Oct '07

09 Oct '07

Hi everyone, I'm trying to build one asterisk cluster using openser to route calls to each machine. I followed a few (many) guides and examples on internet but they simple didn't work very well... I'm using the dispatcher module with openser version 1.1.0-9etch1 (running on a debian 4.0). I have two asterisk (trixbox) machines to do load balancing and failover. I can register in my openser machine with my softphone (twinkle). When I place a call to one extension that exists in both asterisks the call goes always to the second ip in the list. Looking in the debug messages I found the following part: 7(7905) DEBUG:tm:t_should_relay_response: T_code=100, new_code=407 7(7905) DEBUG:tm:t_pick_branch: picked branch 0, code 407 7(7905) ERROR:tm:t_forward_nonack: no branch for forwarding 7(7905) ERROR:tm:w_t_relay: t_forward_nonack failed 7(7905) DEBUG:tm:relay_reply: branch=0, save=0, relay=0 7(7905) old size: 555, new size: 474 7(7905) build_res_from_sip_res: copied size: orig:124, new: 43, rest: 431 msg= SIP/2.0 407 Proxy Authentication Required in my understanding that would mean that I need a password of some kind to relay this message to the asterisk box. The funny part is that the call gets completed and goes always to the same box, the second one in the list. If I change the order of the IPs inside my dispatcher.cfg file it starts to go to the other asterisk, that is the 2nd in the list now. After a lot reading in the debug messages and writing some log messages I found out that the invite request is always going down to the failure route. I think that this is because of the call to t_on_failure("1"); inside my if ( method=="INVITE" ) in the main route, that triggers when the code 407 comes from the password reply... thats just one idea. If there is better way to do this (load balance and failover), please tell me, because I'm pretty new to openser, just trying to make it work for the first time here. my openser.cfg has the following lines on it: loadmodule "/usr/lib/openser/modules/dispatcher.so" modparam("tm", "fr_timer", 5) modparam("dispatcher", "flags", 2) modparam("dispatcher", "list_file", "/etc/openser/dispatcher.cfg") if ( method=="INVITE" ) { #dst_select( "GROUP", "HASH METHOD") ds_select_domain("1","4"); t_on_failure("1"); sl_send_reply("100","Trying"); t_relay(); exit(); } failure_route[1] { if(is_method("INVITE")) { ds_next_domain(); t_on_failure("1"); #if the next domain fails too t_relay(); }; } the rest of the file I didn't mess around with it, so its just the default settings.
