Cbeyond Inc., a managed service provider of VoIP communications, announced it has installed its 20,000th small business customer and processed the four billionth minute of VoIP traffic since the network went live in early 2001. Cbeyond operates one of the largest fully-managed VoIP networks for delivering integrated local, long-distance and broadband services.

Because Cbeyond manages the broadband connection, customers receive the same level of voice quality that traditional telephone companies provide. Many other VoIP companies deliver voice as an application over the public Internet where quality is “best efforts” and highly dependent on the Internet connection.
