Strategies and solutions for successful VoIP deployments
Justify your network investment
Voice over IP (VoIP) is the telephone system of the future. Problem is, VoIP is not yet widely deployed, so there are few skilled practitioners today. As you make your move to VoIP, how will you know how to make VoIP work and keep it working well? What changes will you need to make without disrupting your business? How can you show your return on this investment?
Many books contain technical details about VoIP, but few explain in plain language how to make it run successfully in an enterprise. Taking Charge of Your VoIP Project provides the detailed plans you need to be successful in your organization's deployment of VoIP. Through their years of work in the field, authors John Q. Walker and Jeffrey T. Hicks bring a project-oriented approach to VoIP, with much-needed clarity on getting VoIP to work well.
Taking Charge of Your VoIP Project starts with simple concepts, each chapter building on the knowledge from the last. Although not a technical manual, you learn about the standards, such as H.323, G.711, and Real-Time Transport Protocol (RTP), and the implications they have on your VoIP system. Most importantly, you'll gain expert advice and a systematic guide on how to make VoIP work for your organization.
