Get a solid foundation in VoIP technologies, solutions, and protocols and determine if and when it's time to introduce VoIP into your network architecture. This essential guide offers complete technology coverage, while discussing the business, strategic, and competitive implications of VoIP deployment in corporations. The challenges faced by service providers as they evolve to an IP infrastructure while continuing to operate the PSTN are also examined. Based on a real-world VoIP implementation case study, Voice Over IP Crash Course explains how to perform a functional audit of your pre-existing network to assess its capabilities and deficiencies. Then, you'll find out what it takes to migrate from a PSTN-based environment to a converged IP architecture. Details on hardware and software management, quality of service, backups, and security are also included. If you are considering implementing VoIP, read this book first.
