Calls set up by a conference calling service are inherently different from the multi person calls you might be able to set up from your in house phone service. When using your own phone system, you may experience an uneven balance in volume from one long distance line to the next which becomes increasingly exaggerated as you add callers, making it impossible to conduct your business meeting. With a conference calling service from SimplicityCall.com you will be able to add participants at very reasonable rates and still maintain the quality of your long distance conferencing call.
