Conference calls set up by teleconferencing services are different from the 3 or 4 person calls you might set up from your in-house telephone system. When using your own phone service, you may experience an uneven balance in volume from one line to the next which will become increasingly exaggerated as you add callers, finally making it impossible to conduct your meeting. With professional audio teleconferencing services, each participant’s phone line is routed through sophisticated equipment called a ‘bridge’ that allows participants in the audio conferencing to sound just like they would in a regular 1 to 1 business call.
