What is the best size company for Zerabox or hosted VoIP?
Hosted VoIP, where the server that controls the features and routing of the IP-phones, is best suited for a company with up to approximately 7 or 8 extensions at any single location. Zerabox is a great solution for companies with 5 extensions or more. If a company has multiple locations of 4 or 5 employees, then this could be a good fit for either hosted VoIP or Zerabox.
