Redfone foneBRIDGE2 Single Port T1/E1 to TDMoE

Designed as a low-cost alternative  to old fashioned PCI based cards, the new single port foneBRIDGE2 is a T1/E1-to-Ethernet Gateway. It is an integrated black-box "appliance" designed to streamline installation and enable redun-dant design of Asterisk based VoIP systems.  foneBRIDGE2 eliminates the need to install proprietary TDM  PCI hardware cards in approved or compatible server configurations. Instead, foneBRIDGE2 terminates T1/E1 lines on the trunk side and provides direct Ethernet commu-nication to a network of PBX servers using native Asterisk TDMoE formats and utilities.

Engineered around our unique high-speed SoC (System-on-Chip) TDMoE engine, foneBRIDGE2 provides low-latency delivery of your critical voice traffic.
