Audio Conference Calls | Reservationless - How it Works

How Conference Calls Work



How does reservationless audio conferencing work ?

You conduct your audio conference call without making a reservation or using an operator. As a result, you have total control over the conference schedule.

If you have conferencing participants located outside of the U.S., we will provide international toll free access number.

In addition, you'll receive your PIN's.

1. The moderator receives a unique PIN
2. The conferees receive a PIN
All parties dial-in to your assigned toll free number at the designated conference time you've announced to your participants.

Our automated system will answer and prompt parties to enter their PIN code, followed by the pound (#) sign.

During the course of the audio conference, you may hear beeps.

Entry/Exit Tones and Auto Hangup are standard features, others available.

A single beep indicates someone has joined the conference.

A double beep indicates someone has left the conference.
(this feature is "optional" and can be disabled)

Once the
moderator disconnects from the audio conference, the entire call is disconnected. (this is optional)

Additional Automated Commands Available Using Phone Keypad:

[*2] Initiates unattended conference record function

[*3] Initiates unattended conference playback function

[*4] Applies Gain (volume) to all lines in a conference

[*5] Applies Lecture all conferees except moderators are muted

[*6] Mutes the conferees individual line

[*7] Secures the conference

[*8] Announces the number of parties in the conference

Also #8 will playback a roster of all individuals who are in conference if name record/playback has been programmed.

Although the technicalities and the equipment to create a conference call are completely incidental to you, some of the 'behind the scences' details of how a conference takes place are below:

With a professionally set up audio conference call, each participants telephone line is routed through sophisticated equipment called a audio conferencing "bridge".

This bridging equipment receives and enhances each line electronically, evening out the volume levels, and then sends the electronic voice signal back out to each listening ear.

This allows everyone participating to sound just like they would in a regular one to one call. This way even hundreds of people can be connected in a single audio conference call at the same time with uniform call quality and sound clarity.

In order to achieve this, the participants first need to dial into the bridge. We provide you with a special dial-in telephone number and PIN's. You distribute the dial-in number and PIN's to all intended participants.

At the pre-arranged date and time, all participants dial that phone number and are joined into the audio conference call.



Upon activation of your account, you will receive your account set-up and user instructions. Included will be the assigned toll free access number that you, the moderator, and the invited participants will use for your audio conference meeting.
