Voice and Video
This chapter outlines the steps required to configure voice and video services on the Dell controller for Voice over
IP (VoIP) devices, including Session Initiation Protocol (SIP), Spectralink Voice Priority (SVP), H323, SCCP,
Vocera, and Alcatel NOE phones, clients running Microsoft Office Communicator Server (OCS), and Apple devices
running the Facetime application. Since video and voice applications are more vulnerable to delay and jitter, the
network infrastructure must be able to prioritize video and voice traffic over data traffic.
