Description
Introduction to voice technology and VoIP. Define voice technology, VoIP, SIP and other related terms. Explain the difference between VoIP and traditional phone services. Give an overview of the history and evolution of voice technology and VoIP.Benefits and challenges of VoIP. Discuss the advantages of using VoIP, such as cost savings, flexibility, scalability and integration. Identify the challenges of using VoIP, such as bandwidth, security, compatibility and quality.VoIP protocols and standards. Explain the technical aspects of how VoIP works, such as the transmission of voice packets over the internet. Describe the main protocols and standards that enable VoIP, such as TCP,UDP, RTP, SIP, SDP and others.What is SIP and why is it important? Define SIP and explain its role and function in VoIP and multimedia communication. Describe the benefits and challenges of using SIP. Provide some examples of SIP applications and features.How does SIP work? Explain the basic concepts and components of SIP, such as SIP address, SIP message, SIP session, SIP transaction, SIP dialog, etc. Illustrate the process of establishing, modifying and terminating a SIP session. Compare and contrast SIP with other protocols, such as H.323.What are the types and formats of SIP messages? Identify the two types of SIP messages: requests and responses. Explain the purpose and function of each type of SIP request and response. Describe the format and structure of a SIP message, including the start line, headers and body. Provide some examples of common SIP headers and their values.Explain the role and function of different types of SIP servers, such as proxy server, redirect server, registrar server, etc. Illustrate how SIP messages are routed between different SIP servers and endpoints.How are SIP components identified and authenticated?
