[Users] VoIP tranzit proxy
by Ion Minzu 24 Jan '07

24 Jan '07

Hello , Hello, I have the following situation: UA's ----> openser ----> proxy ------> international 172.19.5.0/24 172.19.5.2 172.19.5.3 traffic A.B.C.D E.F.G.H The problem is about proxy, I need a proxy which would be function as transit between openser (private IP) and a router with a public IP (it should pass the NAT too). I have tested siproxd(http://siproxd.sourceforge.net/) for the case when it sits between the openser (public IP) and the users with private IP - and it works. In the first case siproxd doesn't want to work ( neither as a transparent sip proxy), openser sends INVITE to proxy, it replies 408 Request Time Out. The question is: can RTPproxy or mediaproxy help me in this case? Or maybe there is another solution to solve my problem? -- Best regards, Ion Minzu, mailto:ion.minzu@cts.md

[Users] About Openser version 1.2 (doubts, questions, contribution)
by Danilo Vilela Dantas 24 Jan '07

24 Jan '07

Hi, we are working on a VoIP project and we will use OpenSER as a SIP proxy. This project needs presence and instant message funcionality. We checked out and compiled the CVS HEAD version of OpenSER, but we have a few questions: 1. The modules that implements this two funcionalities (Presence and IM) are ok to use? 2. If question 1 is no, what problems could we have ? Is there any list of bug reports? 3. Is there any date for version 1.2 to be released ? 4. Can we contribute to OpenSER Project ? Thank you very much and Best regards Danilo Vilela Researcher Inovax Engenharia de Sistemas Rio de Janeiro, Brazil

Hi All, I have installed the openser server on linux machine. I followed the procedure given in the link http://www.openser.org/index.php?option=com_content&task=view&id=26&Itemid=… . The server is running fine, but when I try to connect a client (MSN messenger v 5.1) the subscribe message is failing. I have installed the mysql database also given in the website http://openser.org/pub/openser/latest/packages/rhel-3.0/ . The detailed steps I followed are given below. Thanks in advance, Neil

[Users] avp_db_query, NULL AVP?
by Brandon Armstead 24 Jan '07

24 Jan '07

Hello everyone, How is this possible? I have the table usr_preferences, this query runs fine: if(avp_db_query("SELECT value FROM usr_preferences WHERE username = '$fU' AND attribute = 'e911'", "$avp(i:911)")), in other words if I take the query that should be constructed here, and is constructed here, and I run it in mysql cli, I get back a result, however this function "does not" create the AVP for me, no matter what I do, I run this, and I run xlog("L_INFO", "the avp \$avp(i:911) equals.... $avp(i:911)"); however it says its NULL every single time, what am I doing wrong, I've read and reread the AVP documentation over a million times, however can not get this simply working, all help is appreciated, thank you. -- Brandon Armstead

[Users] SMS module modem diagnosis
by Cristian Caprar 24 Jan '07

24 Jan '07

How can I diagnose a problem in the SMS module when opening a modem? I see the following line in the log: DEBUG: modem_process: opening modem After about 5 minutes, I see the next one: ERROR:modem_process: cannot open modem Siemens_S45! Resource temporarily unavailable All happens in libsms_modem.c, line 423, where open() is called. The call blocks for about 5 minutes and afterwards I see the above error in the log. I tried to connect to the modem via minicom (on /dev/ttyS0) and everything is just fine. Thanks, Cristian

[Users] BUG: io_watch_del: invalid fd
by Dan-Cristian Bogos 24 Jan '07

24 Jan '07

Hi Guys, Since a while, I am getting problems with OpenSER while stopping. The error is bellow: Jan 22 09:48:27 localhost /usr/local/sbin/openser[10018]: BUG: io_watch_del: invalid fd 42, not in [0, 0) Jan 22 09:48:27 localhost /usr/local/sbin/openser[10018]: BUG: io_watch_del: invalid fd 45, not in [0, 0) Jan 22 09:48:27 localhost /usr/local/sbin/openser[10018]: BUG: io_watch_del: invalid fd 43, not in [0, 0) Jan 22 09:48:27 localhost /usr/local/sbin/openser[10018]: BUG: io_watch_del: invalid fd 49, not in [0, 0) Jan 22 09:48:27 localhost /usr/local/sbin/openser[10018]: BUG: io_watch_del: invalid fd 48, not in [0, 0) Jan 22 09:48:27 localhost /usr/local/sbin/openser[10018]: BUG: io_watch_del: invalid fd 44, not in [0, 0) Jan 22 09:48:27 localhost /usr/local/sbin/openser[10018]: BUG: io_watch_del: invalid fd 50, not in [0, 0) Jan 22 09:48:27 localhost /usr/local/sbin/openser[10018]: BUG: io_watch_del: invalid fd 47, not in [0, 0) Jan 22 09:48:27 localhost /usr/local/sbin/openser[10018]: BUG: io_watch_del: invalid fd 51, not in [0, 0) If I will start and stop in the first 10 secs, the error will be not in, but stopping it later will always give out the error. I have seen a similar problem, here http://www.openser.org/pipermail/users/2006-September/006982.html, but no solution provided. Did anybody find anything which could help? Is this error serious enough to make me worry more? At a first glance, if I will stop openser, there will come a loot of errors in postgresql database, something related to not closing the sessions properly. My version: version: openser 1.1.0-tls (i386/linux) flags: STATS: Off, USE_IPV6, USE_TCP, USE_TLS, DISABLE_NAGLE, USE_MCAST, SHM_MEM, SHM_MMAP, PKG_MALLOC, F_MALLOC, FAST_LOCK-ADAPTIVE_WAIT ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535 poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. @(#) $Id: main.c,v 1.20 2006/07/04 17:25:54 bogdan_iancu Exp $ main.c compiled on 20:52:20 Oct 10 2006 with gcc 3.3.5 Please let me know if I can help with further info or tests. Cheers, Dan

[Users] Newbie needs some (transparent) proxy help
by ryadave＠gmail.com 24 Jan '07

24 Jan '07

Hi I've just had a project dumped on me to build a sip proxy to sit in front of our Nortel MCS setup (and ultimately other VoIP gateways). Previous admin was supposed to have done this but he recently been given the boot and hadn't even touched this project from what I can see. And I'm a VoIP newbie which doesn't help much - keen to learn but defo a newbie Setup is fairly straight forward from what I can tell but I seem to be doing something completely wrong so seeking help. New sip proxy (OpenSER) is to sit in front of the MCS (and in time other boxes as I mentioned) and it should proxy traffic to/from the sip servers based on the end users realms/domains (i.e. 1234(a)test1.sip goes to server X and 1234(a)tes2.sip goes to server Y) - I'll need to add an authentication layer here but one step at a time. There's no NAT'ing or anything else going on - everything (clients, sip server & sip proxy) sits on public IP space. All I've been able to get to work so far is registration but can't make or receive calls. I've spend 2 days now trying to figure this out (newbie eh ?) and am under increading pressure from management to get this sorted so am getting desperate. I've googled this to death and tried all the various configs that sounded like they would do the job - but none have. I'm sure someone has already done this and would appreciate if you could share the config with me ? thanks dave

[Serusers] Info about my iptel.org blog
by Greger V. Teigre 24 Jan '07

24 Jan '07

Hi, As some of you might have seen (there's a link on the http://iptel.org/ main page), I keep a blog covering iptel.org related things. I comment on threads of particular on serusers and serdev, as well as report on status and my thoughts around iptel.org projects, up to now with a focus on SER and the upcoming new release. http://sipstuff.blogspot.com/ The intention is to improve communication about what is happening on iptel.org, as well as covering things of interest that is maybe not suited for the mailing lists or as a page on iptel.org. However, the posts and opinions are entirely mine and are by no means official attitudes or opinions of iptel.org. ;-) I encourage comments (comments are allowed in the blog), suggestions, discussions on the mailing lists, or private notes related to what I cover in the blog! Cheers, Greger aka g-)
