According to research from Telecoms consultancy Schema, by 2002 more than 20% of international calls from the main European countries will be made using IP technology, at dramatically lower prices than today's PSTN tarriffs. These tariffs are themselves expected to fall to less than half of current levels as deregulation increases competition. The report states the main impact of IP telephony will be in the corporate network market, where it represents a real threat to telcos' leased line businesses.
Schema estimates that IP telephony on corporate networks will grow from virtually zero today to more than 2 million business sites across Europe by 2003.
