Cisco, Intel, RIM, Nokia and others cooperate for VoIP

Cisco said Tuesday the goal of its partnerships with Intel, Nokia, and RIM is to ensure that wireless client devices interoperate with Cisco's WLAN products and are capable of supporting advanced voice features. Cisco already sells a foundation for voice communications over WLANs called its Unified Wireless Network, which includes features such as quality-of-service measurement, roaming, and access points with enhanced radios, the company says.
