In-house wireless 2.4 Ghz phones to ship: this is an interesting development. These phones use existing 802.11b infrastructure to communicate with their controlling equipment, perfect for networks that have already deployed wireless. Here is the press release about the system and the partnership between SpectraLink and Enterasys. The press release notes that voice packets are prioritized. However, if you are using existing equipment, there will be no way for prioritization to be assured as neither TCP/IP nor 802.11b offer scheduling or priority.
