*******************************************************

The samples contained in this directory are complete applications that
demonstrate how to program to TSAPI. Each of these samples builds on the next,
each one implementing more TSAPI functionality than the previous one. These
samples were all written in C++ and built using the Microsoft Developer Studio
and the Microsoft Foundation Classes (MFC). The makefiles (*.MDP and *.MAK)
provided with this sample are specific to that development environment.
However, no complex C++ or MFC techniques were used and there are comments
explaining the MFC code to non-MFC folks.

Porting this code to other platforms will require modifications to event
notification.

These samples build on each other in the following order:

1.	TSAPIOUT - TSAPI Outgoing Call Handling
	
	1 device, 1 call Shows basic outgoing call handling for a single device and
	a single call with no redirection, conferencing, transferring, etc.
	Includes making a call and hanging up the call.
 	
2.	TSAPIIN - TSAPI Incoming Call Handling

	1 device, 1 call Adds incoming call handling to sample 1. Still no
	redirection, conferencing, etc. It demonstrates differentiating between
	incoming calls and outgoing calls. Includes answering calls.
	
3.	TSAPIMUL - TSAPI Multiple Call Handling

	1 device, many calls Adds multiple call handling to sample 2. It
	demonstrates how to keep track of multiple calls at the same device.
	Includes holding and retrieving calls. Also includes redirection as a
	bonus.
	
4.	TSAPICNF - TSAPI Conference Call Handling

	1 device, many calls Adds conference/transfer handling to sample 3.
	Includes tracking of many connections on a single call.



The following files are common to all of the samples:

TSAPI.CPP
TSAPI.H
	helper classes for tracking devices and calls and routines for retrieving
	TSAPI events from the CSTA DLL
	
OPENTSRV.CPP
OPENTSRV.H
	supports the Open Tserver dialog; authorizes the user, opens the TSAPI
	stream and registers the selected device with the TSAPI helper classes

SAMPLDLG.CPP
SAMPLDLG.H
	supports the main application dialog; all call-related control is here:
	making calls, answering calls, call event handling, etc.

STDAFX.CPP
STDAFX.H
	MFC files that do not contain any interesting code for the purposes of
	TSAPI-code demonstration

RESOURCE.H
	resource IDs for the application
