However,\u00a0Cisco is in talks with cell phone makers about the possibility of adding cell phone capability to such a device, which might carry the Cisco brand.The 7920 joins Cisco's 7960 IP\u00a0phone, which sits on a desk and plugs into a wired Ethernet network, and brings the added benefit of mobility around a building or campus that has a wireless LAN. It uses the same type of interface as the 7960, albeit with a smaller display, and lets users enjoy all the features of the company's IP PBX\u00a0wherever the WLAN reaches. The phone will ship in June at least in the U.S. and will be available in other countries soon after, he said.The new phone could be ideal for environments such as retail stores where employees need to move around a site during the work day, Giancarlo said. A phone that combines Wi-Fi with wide-area cell phone capability would be well suited to mobile professionals who frequently use a cell phone for business calls, he added.No price has been set yet for the 7920, which is currently in beta testing. The example shown in a presentation Wednesday was dark gray and looked like a slightly bulky cell phone. To make the product practical, Cisco broke through a high power consumption problem that some industry observers have cited as a challenge for handheld Wi-Fi devices, Giancarlo said. The phone should deliver two hours of talk time and 24 hours of standby time on a charge, he said. It will be available with a cradle that can be used for charging and will have a jack for a headset so employees can use a single phone at work, he added.Companies are starting to embrace IP telephony now that problems such as quality of service have been worked out, according to James Pratt, vice president of sales at Netcom Group, a value-added reseller in Grand Rapids, Michigan, who attended the conference. Customers are turning to IP telephony because it simplifies their network infrastructures and can lower costs, and a mobile IP phone would be attractive to many companies because it would let them add mobility without paying for cell phone airtime, Pratt said. On the other hand, combining Wi-Fi and wide-area cell phone capability on a single device is still hard in North America because there are multiple cell phone technologies in use, he said.
