VoIP Course Descriptions

CVA covers all of the major VoIP, IP and SIP telephone system topics: VoIP equipment, how VoIP is implemented, fundamentals of packetized voice, MPLS, sound quality with sound samples, CoS, SLAs, SIP, SIP trunking and much more.

These courses build on both IP and PSTN fundamentals.
For example, there are four types used for local communications, three used for global communications, five used to support transitioning between IPv4 and VoIP and two special address formats for use when testing networks and for general documentation purposes.
Some of these addresses are created automatically by the machine itself, while others will be assigned with an VoIP DHCP server.
What these addresses are, how they are used in operation, and when which kind of address is used for source and destination is fundamental VoIP knowledge you will learn in this course.
You will also learn appropriate methods and standard practices for an organization-wide addressing plan, including defining subnets and address type considerations.
Whether you are a team leader, developer, manager or administrator, you must be at least familiar with the new address types and how they are used… and this course will give you the necessary knowledge and understanding, in plain English.
