Digital VoIP Gateways

Vega 400G Digital Gateways

Sangoma Vega 400G Digital GatewayVega VoIP digital gateways are small appliances that seamlessly connect your legacy telephony infrastructure, made up of PRI (T1, E1) or BRI lines, to IP networks. 

They are great for businesses with legacy phone equipment (such as a TDM Phone Systems) who want to connect to SIP trunking services without having to spend money altering their current network infrastructure. They are also great for businesses that are already VoIP-enabled at the core (with an IP-PBX) that need PSTN connectivity and require a SIP-to-TDM converter.  

Simply place the Vega VoIP digital gateway at the edge of your network, plug in your existing Internet cable for VoIP connectivity and E1/T1 or BRI cables from your phone system, and let the Vega VoIP digital gateway automatically handle the SIP signaling and voice media conversion for seamless voice and T.38 Fax integration.

The Vega 400G digital VoIP gateway is available in:
