[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.

[OpenSER-Users] mediaproxy server NEW FEATURE!!!
by Gonzalo J. Sambucaro 28 Apr '08

28 Apr '08

Folks, I developed a new feature in the Media Proxy project of AG-Proyect. With this new feature the Media Proxy Server is now able to manage the problem of the NAT IP change in an established call. It is currently in production and working without any problem. Somebody wants to test it? I would like to know what to do to make this feature available to everybody. Does anybody know? Regards, ------------------------------ Details: ------- Supose that there is an established rtp connection between two endpoints and the media proxy is in the middle doing the relay of the rtp streams, let´s say (MP = mediaproxy) EP A <--------->[NAT with IP1]<-----------> MP <--------------------> EP B EP A sends rtp to MP_IP:MP_PORT passing through the NAT box. EP B sends rtp to MP_IP:MP_PORT without passing through a NAT box. The MP know that the caller = NAT_IP1:NAT_PORT1, and the called = EP_B_IP:EP_B_PORT Now, supose that the NAT box change their PUBLIC IP from IP1 to IP2, so this escenary EP A <------->[NAT with IP1]<---------> MP <-------------> EP B will change to this EP A <------->[NAT with IP2]<---------> MP <--------------> EP B so the MP should detect that change of IPs and continue relaying the rtp streams but now to IP2:PORT2 instead of IP1:PORT1. Well, that was the situation y have experienced. To fix this, I developed this solution, changing rtphandler.py file: 1) When the first rtp packet of a source arrives, save the SSRC field in the MP. - Save the SSRC of the caller. - Save the SSRC of the called. 2) If arrives a rtp packet with unknown source IP but with the same SSRC field of some of the two streams, updates the binding (with the new IP detected) between the caller and the MP or between the called and the MP according to the field SSRC previously saved. Note: SSRC (RFC 3550 RTP), (from the rfc: "The SSRC identifier carried in the RTP header and in various fields of RTCP packets is a random 32-bit number that is required to be globally unique within an RTP session ") -------------------------------- -- Gonzalo J.

[OpenSER-Users] "always" serial fork with LCR?
by Amit Sharma 25 Mar '08

25 Mar '08

Hi All, I am a newbie to this list so please forgive me if the question below has been discussed before. I could not find anything related so i am sending my query. I have been looking at the LCR module to do serial forking since we want to prioritize contacts based on q values. However, we do not want to fork in parallel to contacts even if they share the same q value. AFAIK,this is currently not possible with the LCR module. Would it be a good idea to have a parameter (e.g "append-branches") in the LCR module which can control the forking behavior when q value of contacts is the same? Thanks, Amit

[Serusers] Memory Leak Problems
by Ricardo Martinez 19 Mar '08

19 Mar '08

Hello I'm using SER with the LCR module and i'm having some "memory leak" problems. I have followed the "Problem Reporting" link in the iptel.org site to send you a report. My question is : In the page you mention that i need to use memlog=2 and debug=3. Is this ok? or i need to run SER with more debug to see the problem and report it? Second. How do i know if i'm using the last stable, bug free (in theory) version of SER?. SER -V : version: ser 0.9.6 (i386/linux) flags: STATS: Off, USE_IPV6, USE_TCP, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, FAST_LOCK-ADAPTIVE_WAIT ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535 @(#) $Id: main.c,v 1.197.2.1 2005/07/25 16:56:24 andrei Exp $ main.c compiled on 07:54:57 Feb 29 2008 with gcc 4.1.2 i have download this version from the FTP site. I hope someone can help me here. Thanks in advance. Regards, Ricardo Martinez.-

[OpenSER-Users] Dispatcher module
by Mouncif Benniane 11 Mar '08

11 Mar '08

I noticed on version 1.3 (DISPATCHER MODULE) you can set the gateways off Mysql DB, the question is: will be necessary to restart openser every time I add/change the gateway's IP on the DB table (Mysql)?
