Glossary of Key VoIP Phone System Terms

July 8, 2016

VoIP Phone System In addition to the dramatic cost savings and advanced features and options, a big reason why a growing number of businesses are switching from a traditional phone system to a leading-edge VoIP phone system is ease-of-use.

Indeed, a business owner who recently made the switch was quoted by Business News Daily as saying: “When the landline goes down, diagnosing and fixing the issues are never easy or quick, leaving me and my employees extremely frustrated. VoIP is very user-friendly, and having the proper network, we have yet to encounter any significant issues that hinder our ability to communicate with our customers." 

In the same light, understanding key VoIP phone system lexicon is also refreshingly easy. Here’s a rundown of some key terms that you’ll come across as you research options, solutions and vendors:
