Smoothstone

Availability: United States
Founded in: 2001

Smoothstone was one of the first VoIP service providers out there. Founded in 2001, Smoothstone has expanded into the unified communications market. Smoothstone offers network services, conference calling capabilities, and network security in addition to its IP trunking VoIP service.

Smoothstone works directly with its customers and does not disclose monthly rates - they specialize in installation, problem solving, in addition to providing VoIP service. But VoIP review has secured some.

The lowdown on Smoothstone COMPLETE:

Smoothstone's strength is its private network - though it does cost a little more than some of the cheap business VoIP providers, Smoothstone can't be matched when it comes to uptime and security. Since they don't disclose their rates, they are willing to work with you - to get you the best price and the best service. They'll customize their calling plans for your budget.

Smoothstone supports all IP phones and is a great choice for a medium to large-sized enterprise phone network. It might be a little much for small businesses.
