[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 :)

[OpenSER-Users] Acceptor peer failed establishing state[3003], closing
by bhargav.b＠renovau.com 26 May '08

26 May '08

actually i am authenticating a user using openser and opendiameters NASREQ application as the client and server.at present the openser is sending the all needed avp's to opendiameter client.i can see all the avp code and avp data on the client side. my problem is that the on the diameter server side the avp,s are not transferred by the client. the client is giving something like (6372|1698151312) Acceptor peer failed establishing state [3003], closing i am confused about it.by reading some drafts i came to know that the error is due to realm mismatch.but i am sending the same realm as the opendiameter's realm.in both the cases it is [bhargav.s]. before i sent the avp's from openser side there was no such problem showing on the client side.if anybody know the solution please help me regards bhargav.b(a)renovau.com

[OpenSER-Users] UDP Buffer Size / OpenSER / Linux
by Carsten Bock 21 May '08

21 May '08

Hi, short question: Can anybody give me a hint regarding the Linux UDP-Buffer size? Are there any known good values for this or is the default value (128k) of Linux sufficient? I've read, regarding other SIP-Systems (namely IBM SIP Servlets and Communigate pro), the recommendation to increase the UDP-Buffer-size to 3 or even 4 MByte.... Are there any recommended / known best values for heavy load OpenSER Installations? Thanks in advance, Carsten Reference: http://publib.boulder.ibm.com/infocenter/wasinfo/v6r1/index.jsp?topic=/com.…

[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] Radius with additional parameters

Hello! I see how I can receive additional parameters from Radius server via AVPs. But I wonder if it's possible to send additional parameters (headers) to Radius server in requests? For example I want to pass to Radius server P-Asserted header, in case that I need validate it? -- Best Regards, Alex Massover VoIP Development Manager Jajah Inc.
