Audio conferencing is a popular communication technology that is increasingly being used in the professional sphere. In this type of communication system, where many callers can communicate with each other simultaneously, the caller can set the call settings and manipulate the call in such a way that the multiple callers can either participate in the conversation, or merely listen to the call.

In an audio conferencing system, the caller calls more than one person at the same time, and adds all the called parties to the conversation. In some cases, even the called party can call at the conference call number. They can do this by either dialling into special equipment that links telephone lines, called the "conference bridge", or by utilising a special telephone number specially assigned for this purpose. Companies mostly take the services of a specialised service provider for using the conference call facility. They provide the conference bridge as well as the specialised telephone numbers for this purpose.

Audio conferencing is the best solution when an important meeting has to held, and all the necessary participants of the meeting are scattered in different locations. It saves on precious time and prevents tasks and important decisions related to the company from getting delayed. Sometimes directors, shareholders and top mangers of the company may be located in different continents. In this scenario, audio conferencing is the best way to discuss company matters with them immediately, without having to wait for them to assemble in one location.

Audio conferencing facility is also used during client meetings, official updates, project meetings, regular team meetings, training sessions and even sales presentations. It also cuts down considerably on the overall travelling cost if people have to travel to one common location, and it helps in improving the work efficiency of the company.
