[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

Thanks very much!! Yin

[Serusers] Communication Problem btw SER and User Agent

by Adeyeye O. Michael

Hi, Here is an indication that my SER is running: micadeyeye@asmicom:/usr/src/Research-Progress$ ser Listening on udp: 127.0.0.1 [127.0.0.1]:5060 udp: 196.24.224.76 [196.24.224.76]:5060 tcp: 127.0.0.1 [127.0.0.1]:5060 tcp: 196.24.224.76 [196.24.224.76]:5060 Aliases: tcp: asmicom.local:5060 tcp: localhost:5060 udp: asmicom.local:5060 udp: localhost:5060 --------------------------------------------------------------------------------------------------- But each time I tried connecting to it from a USER AGENT (ZAP, UCTIMSCLIENT), it doesn't interact with the client. I checked my dump(via wireshack) but only REGISTER messages are sent with no reply from SER. Can anyone help me? I have both SER and client sitting on same PC (using same port-5060).

[OpenSER-Users] NatPing stop working

by Marcello Lupo

Hi to all, i have openser 1.2.1 active from some months.. Suddenly on yesterday the natping stop to work. I have 140 contacts in user location almost all of them natted. There is some limit to user in location table at which the ping stops or a particular server load? There is a way to have something in the logs about it?? I didn't found anything in the logs. This is my config: modparam("nathelper", "natping_interval", 30) modparam("nathelper", "ping_nated_only", 1) With a restart of openser all come back to work but i'm afraid if it will happen again? Thanks for help, Bye, Marcello

Re: [OpenSER-Users] Broken "BYE" returned from Asterisk on TLS implementation ?

by David Loh

Hi, Arrggghh .. that's one of my attempts to eliminate the broken "BYE" problem... that's ngrep was captured when I set "modparam("rr", "enable_double_rr", "0");", I've paste another ngrep to http://pastebin.ca/674450, this time the double RR header is enabled. And I've posted my .cfg to http://pastebin.ca/Nx0Ss4Fd (key to decrypt the post is "openser"). Even though double RR header is enabled, but for BYE it's still doesn't process properly :( For the .cfg file line #130 onward, I did tried t_relay, forward and force_send_socket, but none of this will do the trick (force_send_socket was complaining TLS error due to missing certificate (?) ) Would appreciate if anyone could enlighten me why is this happen ?
