High-density VoIP gateways are ideal for telecommunications providers who want to offer services such as SIP trunking or value-added services. They are also suitable for companies with large networks that require high capacity and reliable connections. In addition, they are an excellent solution for contact centers, the operation of mobile virtual networks and the provision of VoIP services in retail and wholesale. Thanks to their high scalability, they can handle up to 2,250 SIP sessions and 2,016 channels with SS7 signals.
