Overview

The foneBRIDGE2 Single port is a T1/E1 PRI-to-Ethernet Bridge. It is an integrated blackbox
"appliance" designed to streamline installation and enable redundant design of Asterisk
® based VoIP systems.

Perfect for simple T1/E1 standalone Asterisk installs or complex clustered environments
that require High Availability with minimal downtime.

Dual port capability out of the box without the upfront investment. Through a simple and
cost effective upgrade license the 2nd port can be enabled on demand.

foneBRIDGE2 eliminates the need to install proprietary TDM hardware cards in approved/
compatible server configurations. Instead, foneBRIDGE2 terminates T1/E1 PRI lines on the
trunk side and provides direct Ethernet communication to a network of Asterisk servers using
the Asterisk TDMoE protocol.

Key Features

Failover & Asterisk HA Enabled
• High-Availability through rapid failover capabilities ensures your critical telephony services are always
on and available

Flexible Configuration
• Configurable on a per-port basis, foneBRIDGE2 allows you to mix multiple telephony standards on a
single deployment. Field upgradeable

Solid State Embedded Appliance
