VoIP
Samrat Ganguly & Sudeept Bhatnagar

Het boek ‘VoIP’ is een vrij algemeen boek over VoIP technologie en toepassing. Het gaat in op zowel zakelijk gebruik van VoIP als het gebruik in particuliere situaties (internetbellen). Het geeft een goed overzicht maar heeft niet de ruimte in te gaan op de specifieke zakelijke toepassingen. De verschillende netwerktechnieken worden kort behandeld. Geen boek voor de in-depth technicus maar meer voor de teamleider of het afdelingshoofd dat een algemene introductie nodig heeft binnen VoIP.

Understand how new network technologies impact VoIP! Voice over Internet Protocol (VoIP) is revolutionizing the way people communicate – both in the corporate world and in personal life.

Switching To Voip
Theodore Wallingford

Dit boek geeft een heldere uitleg van VoIP. In dit boek wordt de basis van telefonie uitgelegd, waaronder PSTN, ISDN, signaling, maar ook uitleg over hunt groepen, call forwarding, music on hold, enzovoort. Hierna wordt VoIP uitgelegd: begrippen (SIP, H323, mediagateways, registrars), toepassen van VoIP, eisen aan een netwerk van VoIP en de voordelen van VoIP. Elk behandeld item wordt toegelicht met een praktisch project, waarbij wordt uitgegaan van Asterisk. Deze open source PABX maak je jezelf hierdoor ook eigen. Het boek vergroot de begripvorming van VoIP zowel vanuit technisch en niet-technisch oogpunt. Erg duidelijk uitgelegd in helder taalgebruik. Het boek is engels, maar goed te begrijpen doordat er ‘normaal’ engels wordt toegepast. Een kanttekening van dit boek is dat het voornamelijk op praktijksituaties met gebruik van Asterisk rust. Gebruikt u een andere techniek of heeft u niet de beschikking over een Asterisk testopstelling dan is dit boek minder handig.

More and more businesses today have their receive phone service through Internet instead of local phone company lines. Many businesses are also using their internal local and wide-area network infrastructure to replace legacy enterprise telephone networks. This migration to a single network carrying voice and data is called convergence, and it’s revolutionizing the world of telecommunications by slashing costs and empowering users. The technology of families driving this convergence is called VoIP, or Voice over IP. VoIP has advanced Internet-based telephony a viable solution, piquing the interest of companies small and large. The primary reason for migrating to VoIP is cost, as it equalizes the costs of long distance calls, local calls, and e-mails to fractions of a penny per use. But the real enterprise turn-on is how VoIP empowers businesses to mold and customize telecom and datacom solutions using a single, cohesive networking platform. These business drivers are so compelling that legacy telephony is going the way of the dinosaur, yielding to Voice over IP as the dominant enterprise communications paradigm. Developed from real-world experience by a senior developer, O’Reilly’s Switching to VoIP provides solutions for the most common VoIP migration challenges. So if you’re a network professional who is migrating from a traditional telephony system to a modern, feature-rich network, this book is a must-have. You’ll discover the strengths and weaknesses of circuit-switched and packet-switched networks, how VoIP systems impact network infrastructure, as well as solutions for common challenges involved with IP voice migrations. Among the challenges discussed and projects presented: building a softPBX; configuring IP phones; ensuring quality of service; scalability; standards-compliance; topological consideration; coordinating a complete system? switchover? migrating applications like voicemail and directory services; retro-interfacing to traditional telephony; supporting mobile users; security and survivability; and dealing with the challenges of NAT. To help you grasp the core principles at work, Switching to VoIP uses a combination of strategy and hands-on how-to that introduce VoIP routers and media gateways, various makes of IP telephone equipment, legacy analog phones, IPTables and Linux firewalls, and the Asterisk open source PBX software by Digium. You’ll learn how to build an IP-based or legacy-compatible phone system and voicemail system complete with e-mail integration while becoming familiar with VoIP protocols and devices. Switching to VoIP remains vendor-neutral and advocates standards, not brands. Some of the standards explored include: SIP; H.323, SCCP, and IAX; Voice codecs; 802.3af; Type of Service, IP precedence, DiffServ, and RSVP; and 802.1a/b/g WLAN. If VoIP has your attention, like so many others, then Switching to VoIP will help you build your own system, install it, and begin making calls. It’s the only thing left between you and a modern telecom network.

Speech Quality Of Voip
Alexander Raake

De spraakkwaliteit van VoIP komt in andere boeken ook wel mondjesmaat aan bod, maar dit boek besteed al haar 336 pagina’s aan de spraakkwaliteit. Spraakkwaliteit hangt met erg veel zaken, zoals verbinding, codec, etc, samen en dat komt in dit boek stuk voor stuk aan bod. Het herkennen van de diverse problemen maakt het ook mogelijk deze adequaat op te lossen.

Finally, this title offers a comprehensive overview of speech quality in VoIP from the user’s perspective! Speech Quality of VoIP is an essential guide to assessing the speech quality of VoIP networks, whilst addressing the implications for the design of VoIP networks and systems. This book bridges the gap between the technical network-world and the psychoacoustic world of quality perception. Alexander Raake’s unique perspective combines awareness of the technical characteristics of VoIP networks and original research concerning the perception of speech transmitted across them. Starting from the network designer’s point of view, the different characteristics of the network are addressed, and then linked to features perceived by users. This book provides an overview of the available knowledge on the principal, relevant aspects of speech and speech quality perception, of speech quality assessment, and of transmission properties of telephone and VoIP networks, and of the related perceptual features and resulting speech quality. Discussing new research into the specific time-varying degradations VoIP brings along, but also the considerable potential of quality improvement to be achieved with wideband speech transmission, Alexander Raake demonstrates how network and service characteristics impact on the users perception of quality. Speech Quality of VoIP : presents an overview of different modelling approaches and a parametric network-planning model for quality prediction in VoIP networks; draws on innovative new research on the quality degradation characteristic of VoIP; explains in detail how telephone speech quality can be greatly enhanced with VoIP’s wideband speech transmission capability; assesses the vast collection of references into the technical and scientific literature related to VoIP quality; and, illustrates concepts throughout with mathematical models, algorithms and simulations. Speech Quality of VoIP is the definitive guide for researchers, engineers and network planners working in the field of VoIP, Quality of Service, and speech communication processing in telecommunications. Advanced undergraduate and graduate students on telecommunication and networking courses will also find this text an invaluable resource.
