ESDi allows you to talk to one, or more people, at the same time via your PC.
ESDi is a PA intercom program for Windows 95 or better. Anyone with a PC running windows, audio input source (e.g. microphone/ CD/ mono mix etc), speakers/headset, and a local area network (LAN) connection, should be able to use this application. Being trialware you can download the trial version and try it for free. The only difference between the full version and the trial version is a time limit - 100 hours use. If the trial version works then so will the full version.
Each person has their own ID (e.g. Marketing - Joe). This allows others to call Joe directly. Everyone is part of a group known as 'BROADCAST'. Finally, Joe can belong to up to 9 custom groups. These groups allow people working in same department, or on the same project etc, to interact with each other without disturbing others.
