GNU Gatekeeper 2.2.8 available
by Jan Willamowius 09 Jan '09

09 Jan '09

Hi, we are happy to announce the release of GNU Gatekeeper version 2.2.8. It has a number of new features as well as the usual bug fixes. This release also comes with executables for more operating systems than before. Source code and executables can be downloaded from http://www.gnugk.org/h323download.html Some new features in 2.2.8 are: - new database drivers for ODBC and SQLite - auto-reconnect for all database drivers - extended 'sql' routing policy now supports setting multiple failover routes - support for using stored procedure when using MySQL - ./configure support for Windows - can be compiled to run as a Windows service - support for P2PNAT when compiled against H323Plus - some support for Presence when compiled against H323Plus - support calling by IP via the 'parent' routing policy - outbound number rewrite through SQL/RADIUS modules - selective config reload on the status port Please see the attached changes.txt for a full list of changes. New in this release are executables for NetBSD and Solaris x86. To compile GnuGk 2.2.7 you can use OpenH323 Atlas (OpenH323 1.18.0 / PWLib 1.10.3) or the latest H323Plus release. For high volume installations Atlas is the preferred library. Please see http://www.gnugk.org/compiling-gnugk.html for details on compiling. Regards, Jan -- Jan Willamowius, jan(a)willamowius.de, http://www.gnugk.org/ Changes from 2.2.7 to 2.2.8 =========================== - new RadAcct attribute: RewriteE164 - enable multiple failover routes with sql routing policy - BUGFIX(RasTbl.*) %{last-cdr} was wrong if last call succeeded - forward the destCallSignalAddress in ARQs to the parent gatekeeper (set [Endpoint]ForwardDestIp=0 to get the old behavior) - BUGFIX(RasTbl.cxx) never overwrite dialed_number after is has been set - BUGFIX(RasSrv.cxx) add check to avoid crash on GRQ - BUGFIX(ProxyChannel.cxx) fix reading of fragmented TPKT packets - new switches Called/CallingPlanOfNumber in [RoutedMode] and [EP::...] to set numbering plan - enable SRV policy for all OpenH323 versions as lonng as DNS services are available - global switches for TranslateReceivedQ931Cause and TranslateSentQ931Cause in [RoutedMode], similar to those in [EP::...] - BUGFIX(ProxyChannel.cxx) supress 2nd acct start event for 2nd Setup with same callid - allow outbound number rewrite through SQL/RADIUS modules - rewrite also aliases of type partyNumber (public and private), don't change alias type during rewrite - BUGFIX(MakeCall.cxx) MakeCall didn't work on Windows - implemented status port gai/gci commands for SQLAcct, SQLAuth, SQLPasswordAuth and SQLAliasAuth modules - BUGFIX(capctrl.cxx) added a missing lock during config reload for CapacityControl module - BUGFIX InternalPolicy should set a reject reason to something like gatewayResources/resourcesUnavailable instead of calledPartyNotRegistered when terminating gateways were found, but there was no capacity - BUGFIX(gksql.cxx) SQL reconnect thread-safety fixes - new q931cause variable in SQLAuth module - status port connection can now be closed with Ctrl-D (instead of 'exit') - selective reload on the status port: Reload <AcctConfig|AuthConfig|CapConfig|EpConfig> - BUGFIX(radauth.cxx) fixed crash in processing h323-redirect-ip when no h323-redirect-number is present - BUGFIX (RasTbl.cxx) read GWPrefixes even if there is an EP:: section for this endpoint - BUGFIX (GkStatus.cxx) make sure status port threads don't share string memory with other threads - new compile option COMPILE_AS_SERVICE to create a native Windows service - new config options [Logfile]Filename=, [Gatekeeper::Main]TraceLevel= (same as -o and -t on cmd line) - BUGFIX (ProxyChannel.cxx) always check m_call in H.450.2 call transfer emulator - allow mutiple results per query from MySQL (and ignore all after the first) needed for using strored procedures (patch by Matteo Piscitelli) - Added Bind INI setting to set the default interface for multihomed virtual servers. - BUGFIX (Toolkit.cxx) on reload, check if new config is not empty (Fortytwo=42) - BUGFIX (ProxyChannel.cxx) add NULL pointer checks to avoid crashes - CapacityControl H.323 Id rules work now also for SetupUnreg calls - BUGFIX (ProxyChannel.cxx) make sure Q.931 cause is included in generated ReleaseComplete - new ^= and /= RewriteCLI rules for H.323 ID only rewritting - new getauthinfo/getacctinfo status port commands - Changed P2Pnat from H.460 OID to the standard allocated H.460.23/24 - BUGFIX(RasTbl.cxx): dynamically registered prefixes are added with the GatewayPriority - BUGFIX(GkClient.cxx): use [Endpoint] Type= setting for GRQ, not only for RRQ - merged P2Pnat support - added first cut of Presence support - set radius release-source attribute in stop accounting packet, like %r in sqlacct - ./configure support for Windows - new database driver 'SQLite' - new database driver 'ODBC' - auto-reconnect on database errors (for all database drivers) - allow setting a reject reason when rejecting using the sql policy

how to support directshow
by JobsGuo(Guo Huayong) 10 Dec '08

10 Dec '08

Hi,all. when I compile the ptlib-v2_0_1,I find the config in ptbuildopts.h show below: ///////////////////////////////////////////////// // // DirectX Support (Windows only) // #ifndef _WIN32_WCE #define P_DIRECTSOUND 1 #undef P_DIRECTSHOW #undef P_VFW_CAPTURE #endif So I can not get the directshow support.but I can get the directsound support.I indeed install directx 9.0c.so it can find the directx file. but why it can not find the directshow? Besides,I also can not find the dshow.h. Who can help me ?thanks! 2008-11-28 JobsGuo(Guo Huayong) Mobile：13918103120 QQ ： 360480589 MSN ： ghyhust(a)hotmail.com

swap audio record & player device
by Eleoson Gonzales 01 Dec '08

01 Dec '08

Hello, I would like to use a bluetooth controlled mobile. basically if you connect the mobile to your pc the pc's speaker & mic will become the mobile's speaker & mic. Therefore, I will need to swap the recorder & player device so that h323plus will encode the speaker's audio (player device) and send it to remote endpoint, and decode the microphone's audio (record device) and send it to the local mobile phone. thanks in advance! regards, Eleoson

The CVS code is neutral, compiles in any POSIX compliant system. You will need to inform to the 'configure' program the default system output folder and set proper enviroment variables, some systems need a little more tricks on the config.in file, but not the case of Debian.

IE element decode
by robertp 04 Nov '08

04 Nov '08

lo, i've been harnessing the Q931 class of h323plus to decode packets off the wire, however i'm a little confused as to how h323plus decodes the contents of the information elements which are contained within Q931. i assumed (apparently wrongly) that you would do a check for an element by using Q931.HasIE(), get the byte array of the IE using Q931.GetIE(), then call something like Q931.decodeUserUserIE which returns a structure of some sort which can have methods such as getConferenceGuid() called upon it. I've done the first few steps upto GetIE(), and i now have a PBYTEARRAY of the IE, but i've no idea what to do with it now to decode its contents in a workable, consistent manner. I've poured through the h323+ code, but i cant seem to find where the code deals with this problem. perhaps h323pdu plays a role ?? -- To clarify, i'm sniffing packets off the wire, i.e: mid call, so i'm not an endpoint in the call, rather a onlooker. I don't have transport objects or anything such, i just want to decode the packets and view their contents. - Thanks in advance.

bug in rtp.cxx
by robertp 28 Oct '08

28 Oct '08

line 883 of rtp.cxx is bugged, you're deleting jitter, even if the audio disable has been used for the build. This causes a build error. Also, how reliant is h323plus on the forked sections of ptlib ? Its rather annoying having to build against a customised version. Would it be at all reasonable to make a motion towards merging the ptlib found in other sources such as the ubuntu repositories, and the ptlib given on the h323plus website ? Thanks in advance. - R

Re: [h323plus] How to split audio

RE: [h323plus] How to split audioHi, dansukcu! The best way is deriving H323Codec class and override "write" function (followings for example) and then use it in OpenAudioChannel function. BOOL H323_XXX_Audio_Codec::Write(const BYTE * buffer, unsigned length, const RTP_DataFrame & /*rtpFrame*/, unsigned & written) { ... } BOOL H323_XXX_Audio_Codec::WriteRaw(void * data, PINDEX length) { ... } ... If you want to do more process of the splited audio data, you may also need to implement your own SoundChannel.
