Hi, Have any of you folks seen an abnormal CPU usage issue with rtpprpxy? At times, "top" shows rtpproxy uses 100% CPU (sometimes 99%, sometimes even 101%!), and it stops responding to openser. I have to restart everything now. A small thread in Serdev list recommends upgrading rtpproxy to latest in CVS: http://lists.iptel.org/pipermail/serdev/2006-June/007459.html Mine was fairly old, so I upgraded, but without much progress. What really bugs is I don't know what triggers it. Backtraces suggest that this occurs in different places in rtpproxy, before and after upgrading. Before upgrade: (gdb) where #0 0xb7f49410 in ?? () #1 0xbffd6d88 in ?? () #2 0x00000076 in ?? () #3 0xbffd2410 in ?? () #4 0x4a8d9fd1 in sendto () from /lib/tls/libc.so.6 #5 0x0804ac0c in main (argc=7, argv=0xbffd6e14) at main.c:1467 After upgrade: (gdb) where #0 0xb7f0a410 in ?? () #1 0xbfcb0258 in ?? () #2 0xbfcadfc0 in ?? () #3 0xbfcab8e0 in ?? () #4 0x00bb8dd1 in recvfrom () from /lib/tls/libc.so.6 #5 0x0804a568 in main (argc=7, argv=0xbfcb02e4) at main.c:1364 Any clues? Is this a known problem and is there a patch or some sort ofworkaround? Is there anything I need to upgrade? (This is CentOS 4.4, FWIW) Anything that should be done in openser configuration? Thanks much in advance. - Sajith.

[Users] Abyss XMLRPC server CRLF problem

by jh＠tutpro.com

this discussion on abyss xmlrpc server reminds me about a problem on its handling of CRLF, which needs to be included in a string when applications use t_uac_dlg or send_publish mi commands to send sip requests to openser. if abyss receives CRLF in a string, it drops CR and only LF is left. if abyss server receives CRCRLF, it results in LFLF. abyss does retain CR in a string if it receives if coded as . however, none of xmlrpc clients that i have tried (python or php) allows me to send out on the wire  because they (according to xmlrpc spec) convert & to & and i get on the wire &#13;, which abyss does not convert to CR. the problem results from abyss author's own interpretation of xmlrpc specification: http://xmlrpc-c.sourceforge.net/doc/libxmlrpc.html#xmlrpc_value XML-RPC strings deserve a little more detailed explanation because of some nonsense in the definition of them in the XML-RPC specification. The spec says a string's value is arbitrary 8 bit bytes, but also says that it is part of an XML document. An XML document is composed of XML characters, and the spec doesn't mention any way of encoding those arbitrary bytes into XML characters. It appears that the author was confused about how XML works. as result, i have found no way (without hacking xmlrpc client libraries) to get CRLF via abyss server to openser. does anybody have a suggestion? -- juha

[Users] [Fwd: [Serdev] Contributing new module "prefix_route" to SER]

by Klaus Darilion

FYI: A new ser module which could probably easily ported to openser too (if someone needs this feature) regards klaus -------- Original Message -------- Subject: [Serdev] Contributing new module "prefix_route" to SER Date: Wed, 25 Apr 2007 16:52:39 +0200 From: Alfred E. Heggestad <aeh(a)db.org> To: serdev(a)iptel.org Hi Here is a contribution to the SER community; a new module called "prefix_route" that does prefix-based routing from rules stored in the database. The work was sponsored by my employer, Telio Telecom. The source code is attached, and can also be downloaded from here: http://aeh.db.org/patch/prefix_route-20070425.tar.gz The module has been tested with ser-0.9.6 and ser-0.9.7-pre8 from CVS. It could also be ported to SER 2.0 if there is any interest. The idea with this module is to move the logic of selecting PSTN gateway from ser.cfg to the database. In the database you will have a table called e.g. "prefix_route" which has one entry per rule, matching a prefix to a route number: prefix route ------ ----- 0045 -> route 3 0046 -> route 4 0047 -> route 5 for incoming requests, you can call the prefix_route() function in your ser.cfg - it will then try to match the username part of the request-uri to the "best" prefix, i.e. closest match. if there is a match, it will jump to that routing block in ser.cfg. all referenced route numbers must be declared in ser.cfg, otherwise it will not load. The prefix_route table is populated from the DB at boot or with the "prefix_reload" FIFO command, into a RAM-based tree that is used in execution time. For more documentation, please see the README file ;) I hope that this module will be useful for you, any feedback will be appreciated! /alfred _______________________________________________ Serdev mailing list Serdev(a)lists.iptel.org http://lists.iptel.org/mailman/listinfo/serdev

[Users] uac_replace_from and avp

by CSB

In OpenSER 1.1 I use uac_replace_from to rewrite the from details. I want the rewritten from to be based on an avp value but I don't think that is possible. Am I right? If so, is it possible in 1.2? On a related point, is anyone working on fixing the CSEQ issue with the uac module or is there a plan for this? I know it's been on the todo list for a while. Regards Cameron

Res: [Users] LCR module (1.2.0)

by Bruno Machado

Hi Heinanen When I was using the version 1.1.0, I needed to set a preferred route to my voip 123. This way, it was necessary to insert this underscores after 0. They match any single character (like dot in regular expressions). I used it because the prefix needs to match the longest user part. prefix-------------------from_uri-------grp_id--------priority 0123456------------------------%------------ 1 ---------------1 0________-------------sip:123@.*----------- 2 ---------------0 If I call to number 01234560000 with voip 777, the GW 1 will be selected. Instead, when I use voip 123, the GW 2 is returned. This way, all the calls originated by voip 123 having a size of user part equal 7 or greater, will match with the second line. It does not happens with I have these lines (without the underscores): prefix-------------------from_uri-------grp_id--------priority 0123456------------------------%------------ 1 ---------------1 0-----------------------sip:123@.*----------- 2 ---------------0 In this case, GW 1 will be always selected to any voip. It works in version 1.1.0, but I need to set this behavior in 1.2.0. I know that from_uri in this version is a regular expression. So, I added a '^' in the beginning. prefix-------------------from_uri-------grp_id--------priority 0123456-------------------------------------- 1 ---------------1 0________------------^sip:123@.*--------- 2 ---------------0 The version 1.2.0 always use the LCR in memory. I looked for the query used by 1.1.0 in lcr_mod.h but I didn't find it. So, I don't know if the underscores is necessary because it is used by the MySQL. In my test, just the GW 1 was selected when I called using voip 123. Using other words: I want to route all the calls originated by voip 123 through GW 2 (when beginning with a 0) and the others to GW 1. Thanks for your help, Heinanen.

[Users] ACC : log_fmt equivalent in 1.2 ?

by Will Quan

In version 1.1.0 it was possible to specify the log_fmt for the ACC records that go into the syslog. modparam("acc", "log_fmt", "miocfsur");It appears this has been removed in 1.2, so I was wondering if there is a new way to achieve the same result. That is, produce ACC records with the same syslog format as my 1.3 version.Thanks,Will

[Users] Rejecting SUBSCRIBE/NOTIFY messages

by Andreas Sikkema

Hi, I've been googling for a while and I haven't been able to find out how to do the following: I would like to reject all SUBSCRIBE and NOTIFY messages received by my OpenSER server. How do I do properly? if (method=="SUBSCRIBE") { }; if (method=="NOTIFY") { }; I couldn't find any examples and Google also didn't find anything that pointed me in the right direction. Thanks! -- Andreas Sikkema

Res: [Users] LCR module (1.2.0)

by Bruno Machado

Other thing: the 1.2.0 is using the priority in contrary? prefix----------from_uri-------grp_id--------priority 0123456------------------------------ 1 ---------------1 0123456----------------------------- 2 ---------------0 When I called to 01234560000, GW 1 was selected. In version 1.1.0, the GW 2 will be selected because it has the minor number.
