Simple Certificate Enrollment Protocol (SCEP) eases IT administration by enabling automatic certificate management on the device. End users will enjoy a larger, higher-resolution color display and a user experience that is common with IP Phone 00 Series desk phones. In addition, roaming between access points within the campus will support more seamless voice communications with the 21's support of Fast Transition (02.r). This protocol was specifically designed for mobile voice over IP (VoIP) communications devices within Wi-Fi networks. The 21 supports and/or third-party XML applications such as push-to-talk. 。 。 。
