Upcoming new h323plus 1.26 Release
by Simon Horne 26 Jan '14

26 Jan '14

Guys It's been a while since the last release so it is time to think about a new release. There has been a lot of activity over the last couple of months in the CVS. The build system has been updated and should now build against any version of PTLIB including the current HEAD. However it is recommended that you stick to either 2.10 or the latest public 2.12 release version. A lot of work has been done in signaling and media encryption including adding TLS support and incorporating the updated H.235 spec to support AES256 with large key lengths (up to 8096 bits), H.460.22 support to negotiate when to use TLS and media encryption of the data channel. H.460.26 support has been added and when used in conjunction with H.460.17 allows tunneling of RAS, Signalling and media over a single persistent TCP connection. If using TLS, the h323plus stack will now allow traversal of any secure NAT over a single TLS connection on trusted port such as 443. The matching Gatekeeper support is in GnuGk v3.5. What's new in the upcoming release. ------------------------------------------------ Added TLS signaling support Added H.460.22 Support to negotiate TLS support on a per call basis. Added Encryption support to the H.224 Channel and H323_ExternalRTPChannel Added DH6144 and DH8192 H.235 Support (support for keylength up to 8192 bits) Performance Memory management Improvement in audio/video processing. Updated to compile with PTLIB Head Added Language assignment and routing support Added vs2012 Build environment Fixed vs2010 Build environment Added H.461 Asset Support. Update and fixes for H.460.26 Update Presence System to Version 3 Update Alternate and Assigned Gatekeeper code. Removing buggy pointers Added H.224 Factory loader moved to H224 subdirectory Added T.140 Support Added H.284 <New> far end motorized control add support for <ip>##<room>#<pass> dialing Along with the release there will be updated documentation. Again Special thanks to Jan Willamowius and Yuriy Georgiewskiy for their continued help and support of the project. If anyone finds bugs then please report them ASAP so we can capture them in the next release. Simon

Hi, We are developing an H.323 EP and we need to use the H.235. Is there any example using this? We are using h323plus V1.24.0 and we enabled the H.235. Thanks Claudio

Old Documentation Link
by Diego Carvalho 10 Jan '14

10 Jan '14

Hi All, If you go to the official website (http://www.h323plus.org/) then click in "Source Code", and then in "API Guide" you will be redirected to http://www.h323plus.org/api/v1_19_5/main.html that's the documentation for version 1.19.5, an old version. If possible, updating it to the current version would be great. Thanks in advance.

As usual, you can download the source code and executable for Linux, Windows, FreeBSD, OpenBSD, NetBSD and Solaris from http://www.gnugk.org/h323download.html Regards, Jan New features: - implement H.460.22 to negotiate the use of TLS - language based routing (using the upcoming H.323v8) - new command line switch -mlock to prevent GnuGk from being swapped out - new section [ModeVendorSelection] to set proxy mode based on endpoint vendor support for challenge/response authentication using DES-ECB, eg. from Avaya endpoints - new switch [RoutedMode] FilterEmptyFacility= (Avaya interop) - new switch [RoutedMode] ProxyHandlerHighPrio=0 to avoid setting the proxy handler to high priority; needed to run GnuGk on certain virtualization platforms - print number of proxied calls and peak number of calls in statistics on status port - new switch [RoutedMode] H46023ForceNat - new switch [RewriteSourceAddress] TreatNumberURIDialedDigits - more detailed codec descriptions in %{codec} and Radius attribute - process multiple terminal-alias VSA from Radius - extend [GkStatus::Message] for URQ Configuration changes: - changed default call signaling port from 1721 to 1720 - replace H235HalfCallMediaStrength= switch with H235HalfCallMaxTokenLength= - disable use of SHA1 for TLS by default, the new switch [TLS] CipherList= can be used to customize the cipher selection And a number of bug fixes (see changes.txt for all the details). -- Jan Willamowius, Founder of the GNU Gatekeeper Project Website: http://www.gnugk.org Support: http://www.willamowius.com/gnugk-support.html Relaxed Communications GmbH Frahmredder 91 22393 Hamburg Geschäftsführer: Jan Willamowius HRB 125261 (Amtsgericht Hamburg) USt-IdNr: DE286003584
