Voice over IP with SIP

Introduction to Voice over IP (VoIP) and Session Initiation Protocol (SIP)

This course has been designed to provide delegates with knowledge of the fundamental principles of VoIP (Voice over Internet Protocol). The open standard Session Initiation Protocol (SIP) is described, its function explained and how it fits in with existing network models. A comparison is also made with the ITU H.323 standard. Vendor Specific systems such as Cisco CallManager is included in the course as well as reference to Asterisk Open Source systems.

The course focuses on the theoretical and practical aspects of VoIP, concentrating on SIP, and is intended as an introduction to VoIP software and hardware. Following delivery of the course, the delegates will have a fundamental knowledge of the subject, which will stand them in good stead for further advanced Voice over IP training. This course includes practical modules which allow students to configure VoIP Phones, Softphones, a software IP PBX, and to size a VoIP solution
