The Voicent Tcl/Tk Simple Interface class contains the following functions.
These functions are used to invoke telephone calls from your Tcl/Tk program. For example, callText is used to call a specified number and automatically play your text message using text-to-speech engine.
In order for this class to work, you'll need to have Voicent Gateway installed somewhere in your network. This class simply sends HTTP request for telephone calls to the gateway. Voicent has a free edition for the gateway. You can download it from http://www.voicent.com (MG The Tcl/Tk API is at )
