Our second generation TDM over Ethernet (TDMoE) bridge built for the most demanding Asterisk/Trixbox environments providing High Availability and Load Balancing on T1/E1 lines

Failover and 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

Solid State Embedded Appliance
No moving components. Low heat and power consumption ensures high MTBF (mean time before failure)

Field Upgradeable
Our highly flexible and powerful FPGA architecture allows users to quickly upgrade units in the field when product enhancements and new features are released.

Simplifies Installation

  • True Plug & Play hardware
  • Simplifies cabling; place it wherever is most convenient
  • Leverages commodity servers; no need for a certified box
  • Eliminates requirement for proprietary T1/E1 cards

Fully Asterisk Compatible

  • Employs native Asterisk™ TDMoE format and utilities
  • Follows standard Asterisk™ configuration rules and syntax
  • Compatible with PRI, channel banks and legacy PBX systems


  • T1/E1 PRI Trunk termination
  • Legacy PBX-to-Asterisk integration
  • High-Availability/Failover Asterisk clusters
  • Channel Bank connectivity
  • Mixed telephony environments ( E1 PRIs + T1 Channel Banks)
  • Perfect for BLADE servers where PCI slots are not available.
  • Asterisk and Trixbox Supported


  • PRI Switch Compatibility– EuroISDN, AT&T 4ESS, DMS 100, Lucent 5E, NI1/NI2; Network or CPE
  • Line Interface– Dual or Quad T1/E1 (RJ45), per port configurable
