[Users] new presence server
by Daniel-Constantin Mierla 14 Nov '06

14 Nov '06

Hello, a new presence server which follows the standards and latest draft of SIMPLE has been committed on CVS. With this occasion I want to introduce Anca Vamanu, a new developer which will be in charge of maintaining the presence related stuff. The new module passed successfully a period of tests with common SIP UAs having SIMPLE extensions. It is still long way until we get full SIMPLE extensions, but we have the most desired functionalities: presence info, watcher info and XCAP. Some of you already tested it, and would be great if we can collect the experiences everyone encounters with presence extensions and different UA. There is a dokuwiki page where everybody can contribute: http://www.openser.org/dokuwiki/doku.php/presence:presence-module Since there are not so many mature implementation in client side, the testing proves to be a difficult process, and your help is very welcome. The dokuwiki page includes some sample config files that can be used as starting point. The news on web site and the readme for the module: http://www.openser.org/index.php?option=com_content&task=view&id=62&Itemid=9 http://www.openser.org/docs/modules/devel/presence.html Next on track is a generic module which will be able to publish presence information in behalf of dummy entities. For example will publish online/offline for hardphones registered on user location table. Looking forward to your feedback. Cheers, Daniel

[Users] DST and accounting
by Dimo 14 Nov '06

14 Nov '06

Hello, I have sent this a while ago but it did not come, so if you are getting the mail for the second time sorry. You may be aware of the accounting problem with Daylight Savings Time. Currently in Radius accounting we have a timestamp of the event acoording to system clock (i think). So if a call starts soon before a daylight saving change and ends soon after it, it may have too big or negative duration, depending on whethere the clock moved forward or backward. Is there a way to make accounting take notice of that (maybe accounting in gmt+offset or something?) Any ideas appreciated, as you know DST is comming soon for europe at least. Dimitar

[Users] Newbie questions
by Saúl Ibarra 14 Nov '06

14 Nov '06

Hi I'm new at using OpenSER. I plan to use OpenSER with a SIP proxy (rtpproxy?, mediaproxy?) in order to handle SIP client registrations and connections behind NAT, and then I want to pass the control to an Asterisk server, in order to make the call over an IAX trunk. I've been reading quite a lot documentation on both SER and OpenSER, but I can't figure out how to do it properly. Is there an example or a guide I can check? Thanks in advance. -- Saúl -- "Some people say why, other just say, why not." http://saghul.wordpress.com/

[Users] UAC module. CANCEL request handling.
by Leonid Fainshtein 14 Nov '06

14 Nov '06

Hi, I try to use the "UAC module" for replacing header field "From". I defined the automatic mode for "From" restore (modparam("uac","from_restore_mode","auto")) and change "From" only for INVITE requests. It looks like I also have to change manually header filed "From" also in CANCEL requests. It is because UAC (call originator) sends CANCEL without header "Route" and therefore OpenSer can't perform the automatic replacement. Do I miss anything? Is there a way to implement automatic header field "From" handling for the CANCEL requests? Thank you in advance, Leonid Fainshtein

[Users]Can OpenSER uses same TCP session from the registration in some TLS case?
by Pat wang 14 Nov '06

14 Nov '06

Hi, I am working on the TLS with OpenSER and I found an something interesting. If an INVITE received by OpenSER with a Request-URI of the client AOR then OpenSER proxy the request via the same TCP session established during registration. If the INVITE has a Request-URI of the client's contact URI then OpenSER start a new TCP session. For example: One Eyebeam registers with AOR as: user1(a)tlstest.com and has a contact URI of user1(a)192.168.100.1. When an INVITE contains a RURI as user1(a)tlstest.com then OpenSER look up the location table and replace it with the user1(a)192.168.100.1 then proxy it via the same TCP session as the one during the registration. If an INVITE already has RURI as user1(a)192.168.100.1 then OpenSER proxy this INVITE by starting a new TCP session and Eyebeam does not accept the new session. The call will be failed in this case. I can't find any solution to fix this issue. Could someone know this issue please give some advice?

[Users] OpenSER not working after running for several days
by Papadopoulos Georgios 14 Nov '06

14 Nov '06

Hi Richard, This is a very interesting discussion. However I don't think our situations are similar. Just to make it clear, in your case, did OpenSER slow down or stop working at all? Was it something that happened gradually? In my case, it runs fine for several days. There are no delays, no slowing down of any kind. Then suddenly it stops responding. There is no script change, nothing at all. Actually most of the times it happened during the night when there is nobody around "playing" with DNS, network settings etc. So what could be causing this? Can I set up some sort of logging that will help find the cause of this? I have no clue what kind of information I should be logging. Most of my troubleshooting is done with ngrep. I could redirect this to a log file, but with the volume of traffic that we have, a few hours would be enough to fill the disk. thank you for any help George Disclaimer The information in this e-mail and any attachments is confidential.

[Serusers] fr_inv_timer + avp not working under high load
by Marcus Hunger 10 Nov '06

10 Nov '06

Hi list, I am trying to realise dynamic invite-timeout-timers loading timer-settings per call from my database using avp. It seems to work perfectly on my development-system but fails nearly completly in my high loaded life-environment. According to my logs, timer values are set correctly (eg.: reply_received: FR_INV_TIMER = 15, see modules/tm/t_reply.c:1371), but most of the times the timers have no effect. My setup is similar to http://siprouter.onsip.org/doc/gettingstarted/ch09.html, but avps are not written by hand, but acquired with: modparam("tm", "fr_inv_timer_avp", "mytimer"); avp_db_load("$ruri/username","s:mytimer"); 'mytimer' is an attribute in an usr_preferences-table. Ser's version is 0.9.6. I already searched the list-archives without finding anything regarding this issue. I Also failed accessing the bug-tracker (http://bugs.sip-router.org/), it gave me an internal server error. Has anybody experienced this effect? Is this a bug? Is there a workaround? Best regards, Marcus Hunger

[Users] Measuring QoS with OpenSER
by Andreas Granig 10 Nov '06

10 Nov '06

Hi, I just came across http://www.golem.de/0602/43572.html (sorry, German). It states that AVM contributed GPL'ed source code to OpenSER, which allows an UAC to send QoS measurement samples to the SIP proxy after finishing a call. The goal is to have steady QoS monitoring without changing or extending the network topology. Are these extensions somewhere in CVS or isn't it intended to be released to the public? Andy
