[OpenSER-Users] Limiting maximum simultaneous calls per user

by Sebastian Mangelkramer

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear list, actually I'm searching for a solution to limit the max. simultaneous calls per user. I`ve searched the internet and list-archives for possible solutions. But until now i haven`t found a solution. What i exactly need is to define the max. simultaneous calls per user (e.g. 2,4,6,8,...). I know, that openSER is transaction-stateful, not call-stateful but is there a way to monitor the number of RTP-Sessions per user from Mediaproxy and set the "max_calls"-variable via an AVP? My setup is openSER 1.2.1-notls + Mediaproxy Has anyone implemented such a solution or anyone know such one? Perhaps i had to place a kind of SBC/B2BUA in front of my SIP-Proxy? Many thanks in advance, kind regards Sebastian -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (Darwin) iD8DBQFG3tU87EKQHe5FugIRAi8LAJ0eOVGO10FDjZcTMc7q24TXdfElDgCdHM0g l2ZanHEt/eX9yZTw/jVQxGc= =7Mz4 -----END PGP SIGNATURE-----

[OpenSER-Users] OpenXCAP install and config problem?

by KevinKinnan

I am not sure whether or not my procedure is right as server doesnt work at the moment, but I will keep working on it. Here is the Fedora installation [1] Fedora 6 linux install; [2] pre-dependencies package; Because I installed OpenIMSCore and Openser Presence module before, so some dependencies was already installed. In this case I just installed clearsilver from Add&Remove Package, and copy lxml folder(1.3.4 download from lxml site) to /usr/lib/python2.5/site-packages/. [3] install OpenXCAP, followed installation guide/Debain unstable installation By now, that's it. Coz no daemon can be run from /etc/init.d/openxcap. Also, I haven't modified anything in the config.ini and openxcap files Cheers, Kevin _________________________________________________________________ MSN 中文网，最新时尚生活资讯，白领聚集门户。 http://cn.msn.com

[OpenSER-Users] OpenXCAP install and config problem?

by KevinKinnan

I am trying to install openXCAP on the Fedora 6. Here is my installation procedure: python ./setup.py install; copy config.init to /etc/openserxcap/ copy openxcap to /etc/init.d/ run /etc/init.d/openxcap start update openser config file modparam("presence_xml", "force_active", 0); modparam("presence_xml", "integrated_xcap_server", 0); I havent change anything in config.ini and openxcap it shows some errors "start-stop-daemon command not found". It seems that the openxcap.ini is writed for Debian based Linux as start-stop-daemon is for Debain. How can I run the start file on a red hat based linux? Do I need to do any other modification in some files? Thank You! Kevin _________________________________________________________________ MSN 中文网，最新时尚生活资讯，白领聚集门户。 http://cn.msn.com

[OpenSER-Users] Please help in Openser behind NAT design

by Halomoan Chow

Hi All I'm a new member and trying to use Openser as my VOIP "router" I plan to make following configuration: UA <---> Openser <---> Firewall/NAT <--INTERNET--> Firewall/NAT <---> UA a.a.a.a/24 x.x.x.x y.y.y.y b.b.b.b/24 a.a.a.a and b.b.b.b is internal IP not internet route-able x.x.x.x and y.y.y.y is Firewall/NAT external IP number I know there is mediaproxy and RTPProxy to solve the UA b.b.b.b that behind NAT but I don't know if my decision to put Openser behind NAT is correct or not. How to archive the above diagram with Openser ? If above Openser location is wrong, where should the Openser reside in the diagram? Install in Firewall/NAT or in INTERNET (dedicated server) Thank you for your help and sorry if my question is too newbie Halomoan

Re: [Serusers] Can't make a single call. Help me please.

by Mike Trest - Personal

As a long time VoIP and Internet engineer, we have all seen various port-blocking activities at different levels. These are almost always done to attain economic or political goals. (Remember PANAMA and SINGAPORE). Seldom is it ever for security reasons or for conservation of resources. It is the first question I ask whenever I start to assist a gateway operator who is testing via a cable operator. Therefore, it is understandable that we would be groping in the dark without that bit of bank ground information. Perhaps we should add a guideline note to our FAQ which recommends placing a sniffer/etherial between the originating sip device and the IP network as well as an ethereal/tcpdump on the SER end. ..mike..

[OpenSER-Users] openSER rtpproxy video call - please help

by Volodymyr Fedyk

Hi, I've tried this openser configs from http://www.voip-info.org/wiki/view/OpenSER+v1.2.x+and+RTPProxy and generated by http://sipwise.com/wizard/ and I always face with the next issue: 2 UAs are behind NAT; each UA could call another; IM works; Audio works; but looks-like video streams are handled by openSER and rtpproxy incorrectly, and I'm unable to make a video call to any ua, - I'm using x-lit sp phone, and it shows "Could not start video" on one side, and "No matching video codec" on the other side... Has anybody faced with such issues later or has any ideas ? best regards, Dorin

[OpenSER-Users] Almost the End / End calls OpenSER + mediaproxy + freeradius

by Marc LEURENT

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello evrybody! I have one little problem... When a call badly ends (like hard disconnection or killall mysoftphone) mediaproxy has a timeout of 10sec, after the timeout, it sends a message to freeradius to stop accounting (so CDRTool billing too), but DON'T say to openser to stop the call, so the connection to my SIP/PSTN provider is still up (and its billing too) Is there any way to say to openser to send BYEs when mediaproxy detects the end of a badly ended call? Best Regards! PS: J-20 before VoN Europe 2007 - Rome Extract of the INSTALL file: """If the media session timeouts (there is no BYE that closes the session), MediaProxy will contact back the proxy dispatcher and pass the session media information to be logged. Using this architecture, only the proxy dispatcher needs to have direct access to the database. This addresses the issue of the MediaProxy servers being distributed and not having access to the database.""" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFG3rpwqjpLE0HiOBYRAmbmAJ9UiDDi6UWYg4v+KLR020MwG/ks2ACggg8w aDQX87YSNxjEvy5vcSSeWto= =OCrH -----END PGP SIGNATURE-----

[Serusers] serweb login problem

by Harmeet Singh

Hi I am facing this strange problem, if anyone can help me on this I will appreciate. Here is my configuration - Fedora 7, Apache 2.2.4, php 5.2.2, ser/serweb 0.9.6 When I go to localhost/serweb, enter login info, and submit, I get a download window pop-up asking me to save the php file. Shouldn't Apache be catching this and render the php to html? The login page itself is a php page and that renders ok. So, Apache is configured correctly for php rendering. What else am I missing here? Any help is appreciated. Thanks Harmeet

[OpenSER-Users] XCAP setting problem?

by Adrian Georgescu

You may obtain the XCAP server and the configurations from http:// openxcap.org The latest OpenSER svn version works with it and the sample configuration. Adrian >>>>> I don't know whether or not the xcap_server is set correct. There is no external XCAP server integrated. BTW, I know presence support XCAP function, does it means this module has already included a XCAP server? Thank You! Kevin
