Redfone foneBridge 2

Redfone makes hardware and software products for open-source VoIP implementations, including bridges and gateways. The foneBridge 2 itself is a T1/E1 PRI-to-Ethernet bridge enabled for Asterisk, trixbox, FreeSwitch, Elastix and other platforms, providing Ethernet communication using Asterisk TDMoE (Time-division multiplexing over Ethernet) on Asterisk servers, instead of T1/E1 connections. The appeal of TDMoE for customers is that it offers traditional TDM features over Ethernet instead of pricey TDM hardware.
