RedFone Communications foneBridge2-EC Dual T1/E1 with Echo Cancellation

foneBridge2-EC Dual is a T1/E1 PRI-to-Ethernet Bridge. It is an integrated black box "appliance" designed to streamline installation and enable redundant design of Asterisk based VoIP/PBX systems. foneBRIDGE2-EC eliminates the need to install proprietary TDM hardware cards in approved/compatible server configurations. Instead, foneBRIDGE2-EC terminates T1/E1 PRI lines on the trunk side and provides direct Ethernet communication to a network of Asterisk servers using native Asterisk TDMoE formats and utilities.
