Analog VoIP Gateways

Vega 4×4 Analog Gateways

Take advantage of the newest Voice over Internet (VoIP) technology by connecting legacy telephony equipment, such as private wire connections and other analog devices seamlessly to IP endpoints. Beneficial within the financial sector where Capital Market Traders still require human interaction with their customers, a Sangoma Vega 4×4 gateway seamlessly connects the two disparate technologies.

As technology moves forward with VoIP, some legacy infrastructures are left behind. The Vega 4×4 gateway connects a range of legacy telephony equipment, including PBXs, analog private wires, audio sources and the PSTN to SIP networks. The Vega 4×4 supports up to 16 analog ports on 16 physical interfaces. The chassis is designed to be built out by the systems integrator or OEM to individual requirements.

Four module slots are available for different module types, each with 4 ports, and can be populated in any configuration.

The module types available are:

  • FXO for connection to PBX extension lines or the PSTN
  • FXS for connection to analog telephones or trunk ports
  • Audio for connecting two-way audio sources
  • SIP to SIP call routing
