How this Sample Program Works

This is a very simple telephony program with a minimum of error checking.  etPager shows how to dial a number using our call progress detection to report when the call has been successfully answered.  In our On_Connected event handler routine, we show how to use the etLine.CallSendDigits method to send the call back number to the pager with DTMF digits.  When the OnDigitsSent event is fired, we hangup the phone.
