VOIP Voice Gateway

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.

VOIP gateway 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. VOIP gateway is designed to help maximize investments already made in the existing data and voice network infrastructure.
