Reservationless Services

Reservationless conferencing is the fastest growing application of conference call technology today. You can call our 800 836-3920 Reservations Line and get your permanent Dial-in Number as well as your Passcode. This special combination of Dial in Number and Passcode is available AT ALL TIMES. It will be YOUR set of numbers. You never need to call us again.

How the Reservationless Call Works:

Once you have your permanent Dial-in Number and Passcode set, anytime you want to have a conference you only need to let the participants know the date, time, dial-in number and Passcode. Participants will be automatically prompted to enter the Passcode when they dial in. The Passcode gives the bridge the direction to put each participant into the correct conference call.

As with all CONTACT conference calls, there is always an operator available by pressing *0 (star-zero) anytime during the call.
