Introduction

KDTele Tools represents an effort to develop an ease-of-use, flexibility and powerful collection of components for telephony application development. It is available as a Basic Module with a number of Add-On Modules. The Basic Module includes components that cover the fundamental telephony capabilities, while the Add-On Modules include components that provide extended capabilities.

Basic Module

The KDTele's basic module is compound of two components, KDPhone and KDVoice, which offer the following features:


Make outgoing calls and answer incoming calls.
Detect DTMF tones (the tones heard when pressing a button on a telephone), busy tone, ringback tone, dial tone and other tones. With KDTele Tools, the tone detection is hardware independent - can work without a telephone device capable of decode telephone tones. For instance, you can use KDTele Tools to detect DTMF digits contained in a recorded phone call or perform the detection on-the-fly while recording audio from any source (even from a PC sound card). 
Capture caller ID.
Control of the local phone handset.
Control of the external microphone and speaker of the modem. 
Play and record audio on the phone line or sound card.
Play musics in background mode.
Support realtime encryption during recordings: protect private phone calls.
Support different wave file formats (PCM, IMA ADPCM, Microsoft ADPCM, CCITT A-Law, CCITT u-Law, MPEG Layer-3, etc.)
Timer events to track the progress of playing and recording. 
Silence detection when recording.
VU meter to provide a visual display of the input audio levels.
Playing and recording implemented by multiple buffers to provide continue audio streaming to/from the hard drive.This guarantees that you'll have no restriction to the play/record time other than the disk space. 
Advanced voice detection  to determine when the phone call was answered, and whether the call was answered by an answering machine or a live person.
