▌████ RELEASE NOTES
▌████
▌████ More and more businesses today have their receive phone
▌████ servicethrough Internet instead of local phone company lines.
▌████ Manybusinesses are also using their internal local and
▌████ wide-areanetwork infrastructure to replace legacy enterprise
▌████ telephonenetworks. This migration to a single network carrying
▌████ voice anddata is called convergence, and it's revolutionizing the
▌████ world oftelecommunications by slashing costs and empowering users.
▌████ Thetechnology of families driving this convergence is called VoIP,
▌████ orVoice over IP.
▌████
▌████ VoIP has advanced Internet-based telephony a viable
▌████ solution,piquing the interest of companies small and large. The
▌████ primaryreason for migrating to VoIP is cost, as it equalizes the
▌████ costs oflong distance calls, local calls, and e-mails to fractions
▌████ of apenny per use. But the real enterprise turn-on is how VoIP
▌████ empowersbusinesses to mold and customize telecom and datacom
▌████ solutionsusing a single, cohesive networking platform. These
▌████ businessdrivers are so compelling that legacy telephony is going
▌████ the way ofthe dinosaur, yielding to Voice over IP as the dominant
▌████ enterprisecommunications paradigm.
▌████
▌████ Developed from real-world experience by a senior
▌████ developer,O'Reilly's Switching to VoIP provides solutions for the
▌████ mostcommon VoIP migration challenges. So if you're a
▌████ networkprofessional who is migrating from a traditional telephony
▌████ systemto a modern, feature-rich network, this book is a must-have.
▌████ You'lldiscover the strengths and weaknesses of circuit-switched
▌████ andpacket-switched networks, how VoIP systems impact
▌████ networkinfrastructure, as well as solutions for common challenges
▌████ involvedwith IP voice migrations. Among the challenges discussed
▌████ andprojects presented:
▌████ - building a softPBX
▌████ - configuring IP phones
▌████ - ensuring quality of service
▌████ - scalability
▌████ - standards-compliance
▌████ - topological considerations
▌████ - coordinating a complete system ?switchover?
▌████ - migrating applications like voicemail and directoryservices
▌████ - retro-interfacing to traditional telephony
▌████ - supporting mobile users
▌████ - security and survivability
▌████ - dealing with the challenges of NAT
▌████
▌████ To help you grasp the core principles at work, Switching toVoIP
▌████ uses a combination of strategy and hands-on "how-to" thatintroduce
▌████ VoIP routers and media gateways, various makes of IPtelephone
▌████ equipment, legacy analog phones, IPTables and Linuxfirewalls, and
▌████ the Asterisk open source PBX software by Digium.You'll learn how
▌████ to build an IP-based or legacy-compatible phonesystem and
▌████ voicemail system complete with e-mail integration whilebecoming
▌████ familiar with VoIP protocols and devices. Switching toVoIP remains
▌████ vendor-neutral and advocates standards, notbrands. Some of the
▌████ standards explored include:
▌████ - SIP
▌████ - H.323, SCCP, and IAX
▌████ - Voice codecs
▌████ - 802.3af
▌████ - Type of Service, IP precedence, DiffServ, and RSVP
▌████ - 802.1a/b/g WLAN
▌████
▌████ If VoIP has your attention, like so many others, then Switchingto
▌████ VoIP will help you build your own system, install it, and
▌████ beginmaking calls. It's the only thing left between you and a
▌████ moderntelecom network.
