Voice Gateways

Connect Analogue and Digital Telephones and or Systems to VOIP

Connecting Legacy Equipment to an IP PBX

As enterprises continue to evolve their communications infrastructures into a pure SIP/VoIP environment, they often discover that there is still the need to connect older non-VoIP equipment to their VoIP infrastructure or directly to the PSTN.  Many of these older, but necessary endpoints (i.e. fax machines, postage machines, alarm systems) simply will not function reliably over a VoIP network.

There may also be instances where it is more cost effective to use a “Plain Old Telephone” as an endpoint on a VoIP network, rather than an expensive VoIP phone.   Ruggedized phones may already be in place on construction sites or in other locations where the risk of damage is great.  Entry and elevator phones may already be integrated into existing systems that cannot be easily replaced by an IP endpoint.

A Sangoma Vega VoIP gateway can be configured to deliver a PSTN  dial tone to endpoints that need it, or it can be configured to act as a proxy for plain old telephony, making it appear to the network as an IP endpoint.

Examples of these legacy end-points include:

  • Analog door entry phones
  • Lift/elevator phones
  • Point of sale machines
  • Faxes
  • Modems
  • Franking machines (mail/post provider stamping machine, e.g. Pitney Bowes machine from Canada Post or the UK Royal Mail)

Vega 50 Media Gateway

Connects legacy telephony equipment to IP networks

  • 2–10 Ports, analog or BRI
  • Connect PBXs, ISDN telephones, the ISDN and analog phones to IP networks
  • The most fault tolerant gateways in their class
  • Browser-based GUI interface for quick and easy configuration
  • Voice, fax and modem support
  • Sangoma Network Appliance Provisioning tool makes configuration “a snap”!
  • Flexible call routing for fallback and least cost routing
  • Emergency PSTN backup
  • SIP and H.323 support
Overview

The Vega 50 VoIP gateway creates a connection between any analog or BRI device and a VoIP network. The Vega 50 can be factory configured to support a variety of configurations. When configured for analog telephony, the Vega 50 can support up to eight FXO ports or eight FXS ports with 2 FXO ports. When configured for BRI/ISDN2, the Vega 50 can support up to 8 BRI interfaces. Each BRI interface can be independently configured as network side or terminal side. Therefore, the Vega 50 media gateway can be connected to both a PBX & the ISDN simultaneously. The GUI and browser-based SNAP tool also make the Vega 50 one of the easiest gateways to provision and deploy.

The Vega 50 is an outstanding choice for a variety of enterprise and service provider application:

Enterprise Applications:

  • Resilient branch office support for hosted or premise-based PBX or IP-PBX
  • FXS endpoints and emergency number calling for hosted or premised-based IP-PBX
  • Support for door entry phones, POS, elevator/lift phones

Service Provider Applications:

  • Customer premises gateway for SIP trunking
  • FXS endpoints and emergency number calling for hosted IP-PBX

Analog

  • 4 FXS + 2 FXO
  • 8 FXS + 2 FXO
  • 4 FXO
  • 8 FXO

BRI / ISDN2

  • 2 BRI interfaces (4 channels)
  • 4 BRI interfaces (8 channels)
  • 8 BRI interfaces (16 Channels, subject to MOQ from customer)

Each BRI interface can be independently configured for connection to the PSTN or to a PBX. The Vega 50 media gatewaycan, therefore, be connected to both a PBX & the ISDN simultaneously. This configuration provides:

  • No disruption to the configuration of existing equipment
  • Flexibility & choice for call routing
