For many businesses, the potential to save money on telephony costs is a big motivator to consider a VoIP phone system—if not the biggest one. When compared to traditional telephone hardware, a VoIP system can significantly reduce costs. But look carefully at the included features. Some providers may charge extra for features that others include. If your business is entirely domestic, international calling is only going to inflate your costs, for example. When comparing providers, it’s important to know what features your business needs, and what features you can skip.
