The Ribbon Tenor AF Series is an entry-level gateway that gives small businesses, SOHOs and branch offices with analog voice infrastructures an easy, cost-effective way to capitalize on the power of Voice over IP (VoIP). The Tenor AF offers a complete survivable branch office solution providing support for integrating analog endpoints and the Public Switched Telephone Network (PSTN), while offering back-up call processing support for all Session Initiation Protocol (SIP) and analog calls.
The Ribbon Tenor AF offers a complete SIP-based VoIP solution for the branch office or for service provider customer premise equipment, providing full survivability in the event that access to the central and/or hosted IP PBX is lost. Because it delivers a complete solution in a single device - and because it offers such easy, scalable implementation and management - the Tenor significantly reduces the total lifecycle cost of VoIP deployment, while optimizing service reliability. Tenor also offers PSTN connectivity and legacy equipment integration for both analog and modem based devices.
The Ribbon AF Series comes in three unique configurations depending on its application and location in the network.
