Course Description:
Voice over IP is being widely implemented both within companies and across the Internet. The key problems with IP voice services are maintaining the quality of the voice service and ensuring reach-ability of all users.
Technicians are often required to troubleshoot services beyond just swapping out phones and switches and need to develop skills to identify the source of problems when interconnection between different vendor equipment is involved.
This course will teach you how to use protocol analyzers to capture traffic and analyze the source of problems. It will teach how VoIP services are carried between IP Phones and Analog Telephone Adaptor to IP PBX Servers. It will also teach how SIP protocols used to interconnect servers can be analyzed to test and verify services. Attendees will set up and examine calls inside the classroom and observe how an Internet simulator can be used to introduce the kinds of problems that may be observed when connecting over Internet services. They will then learn how to troubleshoot and fix typical faults.
Students will configure WireShark protocol analyzer, Soft Phones and Asterisk IP PBX software on their own Laptop computers. They will then use this software to learn how to build, test and troubleshoot VoIP services Hands-On.
