What is a VoIP Gateway?

A VoIP gateway is a stand-alone appliance that converts analogue signals to SIP (Session Initiation Protocol) and vice versa, allowing connections between legacy telephony infrastructure and modern VoIP networks.

Digital and analogue VoIP gateways are most popularly used by businesses with a legacy phone system which wants to seamlessly connect to a SIP trunking service without having to change their infrastructure, keeping costs down. They can also be used by VoIP-enabled businesses that want to connect to the PSTN for failover or utilise legacy analogue equipment, such as telephones and fax machines, in their IP network.

Service provider VoIP gateways are used by large organisations to offer telecommunication services to their customers, such as SIP trunking and Value-Added-Services (VAS), and to provide a clear migration path to an all-IP network.

Digital VoIP gateways are small stand-alone appliances which allow you to convert voice media between PRI (Primary Rate Interface) connections or BRI lines (UK) and VoIP connections.

Available in 1 to 8 ports of T1/E1/PRI for connecting TDM phone systems to VoIP networks and IP enabled networks to the PSTN.

Analogue VoIP gateways are small stand-alone appliances which allow you to convert voice media between FXO and FXS connections and VoIP connections.

Available in 4 to 8 ports of FXO and 4-50 ports of FXS for connecting legacy phone systems, telephones and fax machines to VoIP networks.

Mobile and wireline service providers can add new Value-Added Services (VAS) quickly and provide a clear migration path to an all-IP network with Sangoma’s high density VoIP gateways. These gateways are also great for retail, wholesale, and enhanced service VoIP deployments, as well as contact centers, mobile virtual network operations, and mobile VAS.
