This project takes the brilliant work by Equivalence Pty Ltd in OpenH323 and creates a Visual Basic control that can create a new H323v2 client in minutes.
Download the latest OpenH323.OCX
Download the latest VB Example.
Download the VC6 code to create OpenH323.OCX
Current OCX version requires OpenH323 1.1.1 Later versions of OpenH323 from
CVS may cause OpenH323.OCX compile errors. This will be updated on the
next official OpenH323 update.
NOTE: WHEN SETTING UP THE INCLUDE DIRECTORIES FOR VISUAL C, PUT THE C:\OPENH323\INCLUDE
BEFORE ANY OTHER DIRECTORIES. This is because VisualC also distribtures rtp.h which is
different to the Openh323\include\rtp.h
Download Source OhPhone with FFT sound channel to decode DTMF. Uses 256 point FFT to decode DTMF out of H.323 audio stream. Tested with MS NetMeeting on 711 and 723.1 codecs and a DTMF generator. Occasionally trips on voice, some small improvements are probably required. Please try and suggest/make any improvements.
DownloadSource Scan wave file (16bit signed PCM) for DTMF. This what I used initially for debuging. Wave file generated with GoldWave.
