Description: Although networking infrastructure elements—particularly industrial-strength routers and switches—remain the heart and soul of Cisco's primary business, the company is also moving with great force and vigor into the area sometimes called Voice over IP (VoIP), also known as IP Telephony. Whatever you call it (and Cisco's fond of both terms among the language it uses to describe its IP-based voice products and solutions), Cisco expects this niche to become another of its primary business mainstays and is forecasting $7 billion in related business for 2004, with expectations of easily reaching double-digit billions in 2005.
