Deliver Converged Voice and Data on a Managed Trunk

SIP trunking is an in-demand solution -- uniquely offering significant cost savings as well as feature enablement. In the simplest terms, SIP trunking replaces legacy circuit-based connectivity from a company's business telephone system to the outside world.

As a practical matter, SIP trunking creates a connection from a company's private branch exchange (PBX) to the Internet, enabling the Internet to replace the conventional public switched telephone network (PSTN) and allowing business users to communicate via Internet Protocol.

SIP trunking is deployed over a data connection that can be a dedicated line, a shared connection or the Internet. Shift8 provides its partners with the ability to sell SIP trunking as an overlay service to existing broadband access (wireline/wireless, DSL cable, T1/E1, Metro Ethernet, etc.) or bundled with its IP network.  SIP trunking works with a SIP-ready PBX (IP-PBX) or with traditional analog or key business telephony systems by adding an integrated access device.
