MultiVOIP Voice/Fax Over IP Gateways

The MultiVOIP voice over IP gateways provide toll-free voice and fax communications over the Internet or Intranet. By integrating voice and fax into an existing data network, businesses can realize substantial savings on inter-office long distance toll charges. The MultiVOIP family is available in analog and digital models ranging from one to 60 ports. MultiVOIP products connect directly to phones, fax machines, key systems, PSTN lines or a PBX to provide real-time, toll-quality voice connections to any office on a VOIP network. MultiVOIP is designed to help maximize investments already made in the existing data and voice network infrastructure.
