GnuGk turns 15, lets discuss where to take it from here
by Jan Willamowius 17 Feb '14

17 Feb '14

Dear community, this year the GNU Gatekeeper will turn 15 (I did the first release on June 29th 1999). Lets discuss where we should take it from here. I have prepared an anniversary survey with a number of questions on gatekeeper features, security and WebRTC etc. (1 page): http://www.gnugk.org/survey-2014.html Of course you can also chime in here on the mailinglist. (Why is it so quiet here lately ?)

Some issues with h323pdu.cxx
by Denis Kochmashev 14 Feb '14

14 Feb '14

Hello! Please correct me if I'm wrong, but 1. It looks like there is a small mistake in h323pdu.cxx which doesn't allow to build h323plus without H.235 being enabled. 2. I've found that 'H323SetAliasAddress(const PString & _name, H225_AliasAddress & alias, int tag)' doesn't allow to set AliasAddress of type h323_ID if it looks like dialedDigits even if _name begins with 'h323:'. For example, if I specify _name = 'h323:12345', alias tag will all the same be dialedDigits because it looks like them. I suggest a small change to H323SetAliasAddress, because now it produces unpredictable results. Thanks, Denis

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.

Compilation issue
by Diego Carvalho 30 Dec '13

30 Dec '13

Hi All, I'd like to report what I think is an issue. If you compile H323Plus after running configure without any option you will get this warning: [CC] /home/diego/Edifire/Quartz/3rdParty/h323plus/src/h460/h460_std18.cxx /home/diego/Edifire/Quartz/3rdParty/h323plus/src/h460/h460_std18.cxx:54:2: warning: #warning ("H.460.18/.19 Enabled. See Tandberg Patent License. http://www.tandberg.com/collateral/tandberg-ITU-license.pdf") [-Wcpp] [CC] /home/diego/Edifire/Quartz/3rdParty/h323plus/src/h460/h46018_h225.cxx [CC] /home/diego/Edifire/Quartz/3rdParty/h323plus/src/h460/h460_std23.cxx /home/diego/Edifire/Quartz/3rdParty/h323plus/src/h460/h460_std23.cxx:59:2: warning: #warning ("H.460.23/.24 Enabled. Contact consulting(a)h323plus.orgfor licensing terms.") [-Wcpp] Since I don't use H.460, I tried to disable the series that are generating the issues, that is .18/.19 and .23/.24 by running "./configure --disable-h46018 --disable-h46023" but I got the following error: h323.cxx: In member function ‘void H323Connection::DisableNATSupport()’: h323.cxx:2642:30: error: ‘IsH46019Multiplexed’ was not declared in this scope If I disable the entire H.460 support by running "./configure --disable-h460" it compiles successfully and without the warnings I wanted to omit. So that's fine for me but I think there is a bug in the code that is causing this compilation issue. In h323.cxx, around line 2642, the code is: void H323Connection::DisableNATSupport() { #if H323_H460 if (!IsH46019Multiplexed()) #endif NATsupport = false; remoteIsNAT = false; } I think it should be #if H323_H46018 (or both H323_H46018 and H323_H46019M). This is just a guess since I'm not an expert in the H323Plus code. And sorry if this issue was caused by some mistake in my configuration. Best regards.
