Voice Packetization, Codecs and Voice Quality is the "nuts and bolts" of Voice over IP: how the voice is digitized and coded, time stamps applied with the RTP protocol, and how the result is carried in UDP, IP packets and MAC frames.
You'll learn about codecs and compression, and understand factors like delay, jitter and packet loss, what causes them, and how they affect sound quality. Sample sound clips with lost packets and uncorrected timing variations are included so you can hear the effects.
Course Lessons
1 Voice Packetization
2 Measuring Voice Quality
3 Factors Affecting Voice Quality
4 Codecs: Voice Coding and Compression
5 Delay
6 Jitter
7 RTP
8 Protocol Stack: RTP, UDP, IP, MAC
9 Packet Loss
10 Tips for Maximizing Voice Quality
Based on Teracom’s famous Course 130, tuned and refined over the course of over 20 years of instructor-led training, you will gain career- and productivity-enhancing knowledge of how packetized voice is actually implemented and the factors affecting sound quality.

SIP Trunking & Carrier Connections is all about connecting to carriers to communicate VoIP phone calls, both carrier-to-carrier connections and business-to-carrier SIP trunking.
You'll learn how currently the only way for a competitive carrier to terminate a phone call on a Local Exchange Carrier to connect a VoIP call to someone with POTS is at the DS0 level using a gateway. We'll understand why this will be a native VoIP connection in the future, and the role of Session Border Controllers. Then we'll understand how a business can connect to the telephone system using a gateway and PBX trunks, and the advantages of the newer SIP Trunking services for business to PSTN connection.
Course Lessons
1 Introduction + Carrier-Carrier Connection via DS0
2 Carrier-Carrier VoIP Interconnection

IP Network Quality CoS, QoS, MPLS and Diff-Serv focuses on the network service provided by carriers to move packets containing voice, and how network traffic is identified, managed and prioritized, resulting in Class of Service offerings to meet Service Level Agreements.
You will learn how carriers use virtual circuits to manage flows of IP packets, and how MPLS is used to do this. You will understand the idea of Differentiated Services: different transmission characteristics for different kinds of traffic, and how these are implemented as Classes of Service (CoS). We'll cover Service Level Agreements and how "throttling" some users is sometimes necessary to ensure all users are getting the CoS they are paying for. We'll cover the Quality of Service (QoS) mechanisms MPLS and 802.1P and how Classes of Service are implemented by routers.
Course Lessons
1 Course Introduction + Virtual Circuit Technologies
