how to switch a point-to-point conference to multi-party conference
by Bian 24 Apr '08

24 Apr '08

Hi What is the standard way to switch a point-to-point conference to multi-party conference? (The condition is that the codec used in multi-party conference is not same as that in point-to-point call, for example, when in p2p call the endpoint communicate using H.264, and in multi-party confernce they use H.263 codec ) The SONY PCS endpoint's method is that the ep close all logical channels and re-issue capability, then re-open logical channel. I don't know if this is a standard method and if can cooperate with other endpoints. regards, bian ___________________________________________________________ 雅虎邮箱，您的终生邮箱！ http://cn.mail.yahoo.com/

Problem connecting with Polycom VSX 7000
by Abhishek Rohilla 17 Apr '08

17 Apr '08

Hi Has anyone ever tried t connect to Polycom VSX 7000 using H323+. I am trying to do it with both H.261 and H.263. It works fine with H.261 but with H.263 no image is displayed on Polycom side. The call statistics of Polycom show frame rate of 25 but video is blank. i guess there might be some problem with H.263 plugin. Polycom and my machine are on the same LAN. Does anyone have any idea about this problem? please help.

How to know about the remote sides H.239 capabilities?
by Abhishek Rohilla 16 Apr '08

16 Apr '08

Hi Does anyone have any idea about how to know whether the remote side with which connection has been established supports H.239 or not. R Right now I try to open an extended session and check its return value. Is there any call in H323Plus which returns the H.239 capability status of remote side.Since we have already exchanged the capabilities, this information must be available somewhere. Please help!!

Message waiting indications(MWI) for Voicemail messages
by Anisha Kumar 07 Apr '08

07 Apr '08

Hi all , I have a requirement to support MWI in my device, which has support to both SIP and H.323. I see that there is H.450.7 Supplementary Service for that in H.323. But i am not sure practically it is being used in normal deployments. I am trying to find if Asterisk or any other opensource PBX support it.From my analysis i see that Asterisk does have support to MWI for SIP . But could not find out how is the notification done for H.323. Does anybody here have any idea how is it done for H.323 endpoints ? What is the normal means/procedure by which an IP-PBX provides MWI for Voicemail messages to the H.323 endpoints ? Awaiting an earliest positive response . Thanks & Regards, Anisha

Your support solved my problem, now I can use t38modem 1.0.1 with H323. Thanks. Where can I get support for T38Modem to make it work with OPAL ? I DL "cvs -z3 -d:pserver:anonymous@openh323.cvs.sourceforge.net:/cvsroot/openh323 co -D "5/21/2007 23:59:59" opal" but with no positive result... I can run configure only with: ./configure --disable-versioncheck --enable-localspeex After I get a binary, t38modem it's looking for lib pwlib 1.12... with now is 2.0.1 :) Renameing 2.0.1 lib to 1.12, won't help...

Hi , I want to know if the H323Plus code, has support for H.264 Plug-in ? Are there any sample code or application avaiable for the same. We need to have a videoconferencing application with H.264 support. Is it possible to use H323Plus for the same and what amount of implementations will be required for it. Awaiting an earliest positive response. Thanks in advance, Anisha

GNU Gatekeeper 2.2.7 released
by Jan Willamowius 02 Apr '08

02 Apr '08

Hi, a new stable version of the GNU Gatekeeper is now available. Source code and executables can be downloaded from http://www.gnugk.org/h323download.html What's new in 2.2.7 ? Here are just a few highlights: - virtual queues now also work on unregistered calls - per prefix capacity limits - Q.931 cause code translation per gateway - new 'sql' routing policy - auto-reconnect for current MySQL - status port MakeCall command implemented - H.460.9 realtime QoS monitoring - H.460.interop support - H.350 authentication - set multiple failover routes via Radius - alias filtering (eg. for Polycom compatibility) - many bug fixes and a lot more (see the full Changelog below) To compile GnuGk 2.2.7 you can use OpenH323 Atlas (OpenH323 1.18.0 / PWLib 1.10.3) or the latest H323Plus release. Using Atlas should be a rock solid foundation, but some of the very latest features need H323Plus to get activated.

T38Modem support now in H323plus
by Simon Horne 30 Mar '08

30 Mar '08

Guys Just a quick note T38modem has been added to the list of open source applications supported with h323plus. Special thanks to Tamas for testing and providing his support for the application. You will need the latest patch ptlib 2.0.1-3 for Linux and h323plus v1.20 to ensure it runs stable. You can download the source code from the h323plus website. Simon Note: This project is still officially being developed with Opal however Tamas has offered to maintain the existing OpenH323 (now H323plus) version.
