RingCentral, whose online services allow small businesses to unify and manage all their phone, mobile, fax and email communications, launched DigitalLine, a Voice over Internet Protocol (VoIP) service. DigitalLine is seamlessly integrated into RingCentral's hosted phone and fax service, allowing customers to place and receive calls using a broadband Internet connection.

The service targets very small businesses. Unlike other providers offering VoIP services, RingCentral does not require businesses to rely solely on VoIP. By integrating all communication lines (mobile, home, office and fax), RingCentral provides a way to leverage all the available communications technologies in the most time- and cost-efficient manner.

As part of every basic service plan, DigitalLine enables customers to receive calls over the Internet at no additional cost. With RingCentral, small businesses and mobile professionals can interact with customers more professionally, using all the features of a big company phone system at a fraction of the cost and all under a single phone bill. RingCentral has over 40,000 customers, citing 85% year-over-year growth, and said it is signing up thousands of new customers each month.
