PhonePower, our top-rated residential provider, offers their high-reliability, customer-friendly service to small businesses for a very reasonable price. The quality of their business service certainly measures up to the standards set by their residential offerings.

If your business needs two lines from the start - for a second employee or maybe for a fax machine - ITP's small business VoIP service is your best bet, and offers an excellent price while maintaining the same excellent level of quality and reliability that their residential customers have come to expect.

Though 8x8 is certainly the top business VoIP provider around, their small business offering is a bit on the expensive side. They make up for this, though, with their high quality equipment and vast range of features and addons. They are worth looking into if your business is going to make significant use of the phone.

Vonage's large network ensures good reliability, but we feel that their standard set of business features can't quite justify their pricetag.

8x8 has the features, reliability, and equipment to effectively serve the telecommunications needs of medium sized businesses better than any other VoIP provider on the market.

ITP offers both hosted PBX and SIP trunking plans to larger businesses requiring 3+ phone lines. Their SIP trunking plans cost slightly less than the hosted PBX lines listed below, but both are excellent deals, and are backed up by the same quality service that marks all of ITP's offerings.

PhonePower recently added multi-line hosted PBX business plans with a host of useful addons and upgrades. Their services are low-cost, easy to setup, and highly recommended for small-to-medium businesses (10-30 employees).
