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.
