This advanced course will show you how to optimize the operation of VOIP applications in your data networks. Subjects covered include isolation in a multimedia VLAN, multicast traffic, different options for QoS configuration, and the interoperability of the SIP protocol.


Teaching objectives
At the end of the training, the participant will be able to:
Optimize the operation of VOIP applications
Implement a network consisting of a multimedia VLAN
Configure a Cisco router as a SIP-Analog Phone Gateway
Implement a RADIUS server with a certification authority

Intended audience
System and network administrators and engineers.

Prerequisites
Good knowledge of the TCP/IP, SIP and H323 protocols. Or knowledge equivalent to that provided by the course "Voice Over IP: Implementation" (code VON).
