Office Intercom Audio Communication Software

Push-to-talk with this Internet IP Intercom

OfficeIntercom lets you use your PC to speak to others over the internet or a local area network with simple "push-to-talk" technology.

It works as a virtual IP intercom and feels a little like using a CB radio. Talk to anyone else who has installed OfficeIntercom anywhere in the world from your PC.

OfficeIntercom is designed to be fast and easy to use and, in an office environment, no cabling is be required to run OfficeIntercom because it uses the existing computer network.

Note: OfficeIntercom is no longer supported by NCH Software.
It is now part of Express Talk Softphone.
