Desktop IP (Internet Protocol) phones inched closer to computing platforms with Cisco Systems' announcement of a phone with a color touch-screen and the addition of XML (Extensible Markup Language) application support to two of its less expensive phones.
IP phones can send and receive data as well as voice calls over the same kind of network that carries Web pages and application traffic. Cisco makes a wide range of IP phones, some of which already can be used as platforms for XML applications such as instant messaging, inventory checking, employee directories, flight schedules and headline news services.
Last week, Cisco unveiled the IP Phone 7970G, its first phone with a colour display and a touch-screen.
The new features made the phone easier to use and would let developers write applications that use images, director of product marketing for Cisco's IP Communications group, Troy Trenchard, said.
In addition, the company upgraded its lower-end 7905G and 7912G phones with XML support.
Those less expensive phones had small monochrome displays best suited to text-based software, he said.
The introductions came on the eve of Cisco's Innovation Through Convergence Expo in California, where Cisco partners show off a variety of XML applications that can run on the phones.
The introduction of more advanced IP phones, as well as voice-calling applications on PCs, was starting to blur the line between handsets and computers, Yankee Group analyst, Zeus Kerravala, said.
"You may have a PC with voice capability, but you'll also have a phone with other capabilities," Kerravala said.
In some cases, such as in the lobby of an office building, organisations may be able to get rid of the PC all together, he said.
As phone functions increasingly become integrated into software, a key challenge for Cisco was how to cultivate relationships with independent software vendors it wanted to write applications for its phones, Kerravala said.
The 7970G will begin shipping in the US by the end of this year and be generally available in the first quarter of 2004 at a list price not to exceed $US995, according to Cisco.
The 7905G and 7912G are available now for $US135 and $US165, respectively.
The enhanced XML capabilities are set to become available at no cost in the upcoming release of Cisco CallManager software near the end of this year.
The next release of CallManager will automatically add XML capabilities to phones that are already installed.
