3Com has released a new cordless voice-over-IP (VoIP) phone, targeted at business customers who tend to move around the office a lot in their jobs. The phone uses Session Initiation Protocol (SIP), which means it\u2019s compatible with standard networking equipment that a business might already have. It is also compatible with standards-based wireless LAN infrastructure.3Com expects that such phones will appeal to workers in education, government, health care and retail who spend much of their time away from a desk. Users can transfer calls to other employees, reach a receptionist, listen to voice mail and read e-mail on the phone. They can also customize personal settings such as ring tones and speed dials. The clamshell phone uses Wireless Protected Access 2 and encryption for security. It is called the 3Com 3108 and is available now for US$415. Such standalone Wi-Fi phones may compete with converged cellular and Wi-Fi phones that operators are just starting to introduce. The Wi-Fi-only phones could have advantages over some of the combined offerings because they don\u2019t incur any per-minute usage fees and may work better indoors, although users who leave the corporate campus often might have to carry a separate cell phone and number.3Com is competing with other Wi-Fi phone makers, including networking giant Cisco Systems, SpectraLink and Siemens. Earlier this year, Nokia began selling its Eseries of phones, many of which come with both cellular and Wi-Fi and support SIP for wireless VoIP calls.-Nancy Gohring, IDG News Service (Dublin Bureau)Related Links:\n\nPhilips, Netgear Unveil 1st PC-Free Skype Phones\n\nKeySpan Unveils Skype-Compatible, Cordless VoIP Phone\n\nExperts: VoIP Represents Serious Security Risk \n\nVoIP Security: When Voice Becomes Data\u00a0(CSO)\n\nSkype Preps Enterprise-Friendly VoIP SoftwareCheck out our CIO News Alerts and Tech Informer pages for more updated news coverage.
