...IP telephony is even making inroads into the wireless industry. For now, most hospitals ban cell-phone use in patient areas because the phones can produce electromagnetic radiation that interferes with hospital monitors. That has forced patients and nurses to rely on archaic paging systems. Evanston Northwestern Healthcare in Evanston, Ill., recently decided to begin using a voice-over-IP-enabled device from Symbol Technologies of Holtsville, N.Y., on wireless networks in its three hospitals. The device, which combines PDA functions with voice, offers several benefits: it doesn't suffer from interference, as cell phones do; it lets patients connect...
...Mitel Networks, NEC, Nortel Networks and Siemens, which are all pitching products to move customers from traditional phone systems to a converged voice-and-data network. On the other side, network-equipment makers like Cisco and 3Com are suggesting that companies dump their phone providers entirely and go with IP-enabled systems and phones. IP start-ups like Pingtel, Shoreline Communications, Sylantro, Veraz Networks and Vertical Networks are pushing both sides to innovate...
...added services that the voice-data combination is just beginning to make possible. For that reason, most of the major phone companies--AT&T, BellSouth, Qwest Communications, Sprint and Verizon--have already announced a VOIP offering of some sort. They too are responding to upstarts like end-to-end IP service provider GoBeam, based in Pleasanton, Calif. Ultimately, residential customers will reap some of the same rewards...
Despite obvious benefits, many businesses are reluctant to throw away their current phone systems, especially since they work just fine. Companies like Avaya, Citel, Mitel and Nortel offer equipment running "converged systems," which let companies operate traditional phone systems alongside an IP network. "You only need to migrate those people who actually get some benefit from having a new device on the desktop," says Donald Peterson, chairman and CEO of Avaya. "For people who sit at the guard station at the back door, you can leave the existing devices there...
...folks at Cisco and 3Com argue, of course, that everyone should get on an IP-based network--at once. Those who wait, they say, will fall behind competitors not only in cost savings but also in learning how to use a converged network as a strategic asset. "There's no question at this point that all communication will ultimately be IP based," says Charles Giancarlo, senior vice president of product development at Cisco. He may be right: most businesses now outfitting new offices for telephony tend to go with VOIP instead of traditional phone lines...
