[OpenSER-Users] rtpproxy
by Kent Poppenhouse 16 Aug '07

16 Aug '07

I have a question about the nathelper module. specifically the rtpproxy_disable_tout, rtpproxy_retr, and rtpproxy_tout parameters. I have openser running on one machine and rtpproxy on another. Everything works great if the rtpproxy is up and running before starting openser. However, if rtpproxy is not running first, openser never connects to it. I set the following parameters in my openser config file: # -- nat params -- modparam("nathelper", "rtpproxy_sock", "udp:10.100.103.1:8899") modparam("nathelper", "rtpproxy_disable_tout", 30) modparam("nathelper", "rtpproxy_tout", 2) modparam("nathelper", "rtpproxy_retr", 10) based on this I would think openser would try to connect to the rtpproxy 10 times with a 2 sec timeout. If after 10 retries no connection is made, it would wait 30 s before attempting to connect again. Is this correct? If so, what am I missing since it doesn't do this. I'm using openser version 1.2.0. Thanks.

by Daniel-Constantin Mierla 16 Aug '07

16 Aug '07

Hello, version 1.2.2 of OpenSER has been released. This is a minor release in the branch of 1.2 release series, containing only fixes to bugs found since the previous release 1.2.1. See all changes at: http://www.openser.org/pub/openser/1.2.2/ChangeLog The configuration script used with any 1.2.x version is compatible. There was a change in the structure of table "active_watchers" for handling local and remote CSeq numbers -- you have to recreate this table if you are using presence module (instructions are provided here: http://openser.org/dokuwiki/doku.php/install:1.2.1-to-1.2.2). Source tarball can be downloaded from: http://www.openser.org/pub/openser/latest/src/ Or from sourceforge download page: http://sourceforge.net/project/showfiles.php?group_id=139143 Download page providing several options is available at: http://www.openser.org/mos/view/Download/ The documentation for modules is posted at: http://openser.org/docs/modules/1.2.x/ Main documentation page is available at: http://www.openser.org/mos/view/OpenSER-Documentation-Repository/ If someone wants to contribute with packages for different distros, please send the link from where can be downloaded to team(a)openser.org. We would like to thank to all developers and contributors for their work with coding and testing for this new release. Cheers, Daniel

[Serusers] Presence annoyance.
by SIP 16 Aug '07

There is now a Grandstream GXV3000 in my network (neat little videophones, I must say). However, when someone sends a presence event through my server, the grandstream responds with a SIP packet and additional XML info: U 99.101.102.103:5060 -> 172.17.240.240:54330 NOTIFY sip:1101XXXXXXX@172.17.240.240:54330 SIP/2.0.

[Serusers] presence server 2 presence server
by cherami＠gmx.de 16 Aug '07

16 Aug '07

Hi, I am student and new to the Presence Model und Protocols. I have in my student project the following scenario: company A wants to develop a presence service PA. The presence service PA should get the data from the presence server PB of an other Company B over the Internet. The Presence information of PA should be made available in the Company A for different applications. my question: can PA poll or subscribe all changed/updated Presence Information from PB regularly. Or it should request the Presence Information of each Presentity individually? which Presence server can implement the presence service PA. What should I do if PB uses another Protokoll? Thank you and Best Regards Koder -- Psssst! Schon vom neuen GMX MultiMessenger gehört? Der kanns mit allen: http://www.gmx.net/de/go/multimessenger

Hi, i attempt to connect ser to a sip provider with user + password authentication. if i get it right, i have to load the uac modul and insert following line: modparam("uac","credential","user:sip-provider-ip:password"), but i can't find the uac modul .. i hope anybody can help me .. another way i tried is this one: route[x] { rewriteuri("username@sip-provider-ip"); rewriteuserpass("username:password"); rewritehost("sip-provider-ip"); forward("username:password@sip-provider-ip"); } but it worked either. it comes always up with: get_connection(): Connection not found in the pool .. kind regards, julia heller -- Der GMX SmartSurfer hilft bis zu 70% Ihrer Onlinekosten zu sparen!

[OpenSER-Users] question about DIALOG module
by Victor Gamov 15 Aug '07

15 Aug '07

Hi All As I understand dialog may be terminated by DIALOG module, e.g. due session timeout. In this situation module sends BYE timeout. When RTPproxy used does it receive signal to close RTP session whel local BYE generated? One more question -- is it possible to terminate session when RTPproxy does not get RTP packets for some predefined time? may be RTPproxy must be extended? Thanks! -- CU, Victor Gamov

Hi friends I have been on the look out for someting related to performance counters or statistics in SER. If i browse through the code, I find, that there is #ifdef STAT macro defined, which is used if STATs are enabled while compilation. Now, when i try to do that, it looks for a SNMP module related files... which it doesnt find... On searching on internet i find a page saying SNMP is dead... Can any one help me in finding out how to enable statistics for SER?
