VoIP Phone Service: What is VoIP?
VoIP Phone Service: Toll Cost-from my office to another of my offices
If you are a small business with multiple offices and have a substantial amount of telephone traffic between your locations then there may be some justification for installing a VoIP telephone system. If you already have a data connection between the offices or if all of the offices have an internet connection then you could send telephone calls between your systems over the data network at no additional cost per call or per minute. It is possible that you could save from hundreds to thousands of dollars a month if you have enough locations and enough phone calls between offices.
