Quorum Telephone Conference Server

Phone Conferencing Software for Business

This is a legacy program we no longer support.
Security Notice: The person you setup as admin on this program can have access to files on your system.
Quorum is software which runs as a phone conference server on any Windows PC. Callers dial into the server to join telephone conferences.

Callers can connect to a conference call using either standard or VoIP lines on external telephone numbers or through an office phone system. The number of people who can join a conference call is limited only by your bandwidth.

When the caller selects the option to create a new conference Quorum will assign and read back the unique and secure conference number. The conference creator then gives this number to each conference participant. Whenever any person dials the server and enters this conference number, they will join in the current conversation with the other members of the conference.

Quorum is just one part of the NCH Software telephony suite. We also have a number of other phone related applications that will work in conjunction with Quorum. See our Telephone Software Guide for a complete list.

In particular we recommend the Axon VoIP Based PBX to route calls to Quorum, and the Express Talk VoIP Based Softphone for free VoIP connections to Quorum via the Internet.

For a more informal conference option for 2 or 3 people, try the conference feature on the Express Talk softphone.
