also known as a sound teleconference bridge, the sound bridge is a piece of equipment used to create telephone conference calls. The sound bridge serves as a termination point for connection to take place in a collective call, and create a common hub where all lines can easily connect and interact. The sound bridge is the oldest type of teleconference bridge and is still used regularly in many parts of the world.

The sound bridge has been in production since the mid -20th century. The earliest patterns were large and somewhat cumbersome pieces of equipment that were extremely expensive. Usually only telephone service providers owned sound bridges, although at the end of the 1960s some larger corporations with their own internal communication systems used audio bridge facilities to carry out conference calls between the company's devices that were part of the internal network.

with the deregulation of the United States in 1984Isle of conference call providers. Some proposed their own proprietary sound bridges and introduced contracts with local and long carriers to supply the capacity of the line necessary to provide the services of their clientele conference calls. Much smaller than bridges of the 50s. The 20th century. The newer bridges had larger line capacity and it was much easier to handle them in terms of dialing and connecting the conference participants.

with the arrival of 90. The sound bridge began to be subject to other changes. Many bridge manufacturers have left older analog technology in favor of newer digital configurations, allowing to increase the capacity of the line on the bridges and also provided a more sensitive level of sound quality on calls. Together with upgrades in capacity and sound, the newer Sound Bridge Designs also allowed participants to dial into the bridge device to require the operator to pull out each individual that CHystá to participate in a conference call. This new approach, known as dial-in or conference Meet-ME , was even easier to create unique cards that could be used to rout each caller for the right conference call.

This has led to the creation of a voice internet protocol or VoIP, sound bridges that rely on the location of the device when the phone switch converts the online audio currents to standard digital phone signals at each end of the connection. The final result was the constant decline in the cost of the sound toOnfection, which allows this service available to businesses of all sizes and individuals.

Today, the sound bridge is sometimes covered with video capability. This hybrid bridge uses the same circuits to transport both voice and video, rather than requires two separate appointment devices. The sound video bridge, which is more expensive than the traditional sound bridge, has increased in popularity in recent years, especially among corporations with international presence.
