Office Intercom is a lightweight Windows application designed to help you speak to other users over the Internet or local area network.

When you run the utility for the first time, you are asked to configure the preferred talk mode and audio quality options.

You can pick the communication device, namely microphone speakers (turn on echo cancellation), headset (turn off echo cancellation), or Express USB phone. The audio quality can be tweaked by selecting low or high bandwidth usage.

What’s more, you are allowed to choose the sound recording device, audio input channel, and volume level, as well as check if the speakers or headphones and playback volume are working correctly.

Office Intercom gives you the possibility to change the volume of the microphone and speakers directly from the main window. You can show or hide a log panel in the GUI that records details about all actions and possible errors.

You can assign system hotkeys for direct connections without having to open the application, encrypt your voice with private keys, allow only certain callers to contact you, as well as enable the ‘Do Not Disturb’ mode in order to stop others from talking to you.

The tool lets you store contacts and add information about them, such as name, home number, SIP address, mobile phone number, and email address. There’s support for a built-in contact manager that allows you to edit or remove contacts and import/export contact information from/to CSV file format.

All in all, Office Intercom integrates a handy suite of features for helping you communicate with other users. On the downside, it hasn’t been updated for a while, so you can make use of its capabilities especially if you are the owner of an old operating system, such as Windows 2000, XP, 2003, or Vista.
