How Internet Phone Service / VoIP Works

Have you heard of Internet phone service / VoIP? Perhaps you have used this modern technology yourself, but do you know exactly how it works. Take a look at this overview of the process in order to understand just why this system of calling is so popular and so cheap.

Technical Aspects

Technically speaking, VoIP takes your voice and converts the sound into a digital signal that can be carried across the internet – and thus around the globe. Additionally, if the person on the other end is using a regular telephone, another conversion is made in order for them to understand the sound as regular conversation.

Equipment Needed for Internet Phone Service / VoIP

VoIP calls are accomplished with the help of certain software and hardware. If you are communicating strictly with a computer, then only software is required. If you are using a regular telephone, then you must also have an adapter to connect it to the internet. Either way, incoming phone calls utilise a ringing sound to provide an alert for an incoming call.

Of course, in order for the digital signal to travel across the internet, a connection is required. It must be high speed, such as a broadband connection via a cable or DSL modem. Wireless VoIP communication is also possible via internet access points in hot spots such as airports, libraries, municipalities, etc.

For use with a computer, VoIP will require a microphone and speakers in order to speak and hear the sound. Some consumers who use this service with their PC prefer to connect a headset in order to ease the communication process and keep the other side of their conversation private.

With a regular telephone set, users can dial just as they would normally, however some companies require that a specific access number be dialled first. Check with the individual service provider to determine the exact procedure.

Save Money

Many times Internet phone service / VoIP is offered at a deeply discounted rate along with the features most consumers have come to expect from cell phone service providers. These include free long distance calls, call waiting, call forwarding, etc. Because you are only utilising your broadband internet connection, there are no additional fees for setup and other monthly services, making it quite cheap.

There are many benefits when using Internet phone service / VoIP for your personal and/or business needs. Perhaps the biggest advantage comes from the cost savings. Check out the options available to you in order to start using this modern technology and start saving money on your telephone bill right away.

Switching to VoIP $31.99 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 to 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 considerations coordinating a complete system ?switchover? migrating applications like voicemail and directory services 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 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 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 ma
