What is VoIP? An introduction to VoIP technology - how VoIP works, its pros and cons, its advantages, its risks, its technicalities, voice quality, and definitions of key terms used when referring to Voice over IP.
Voice over IP Defined - Voice over IP allows you to make free or very cheap phone calls locally and internationally. It is also called VoIP and Internet Telephony. Voice over IP also adds more power and spice to your communication experience with its wide array of features and applications.
What is telephony? Telephony is a term denoting the technology that allows people to have long distance voice communication. The term’s scope has been broadened with the advent of the different new communication technologies. In its broadest sense, the terms encompasses phone communication, Internet calling, mobile communication, faxing, voicemail and even video conferencing.
To communicate through VoIP, you need to use a service. There are many types of VoIP service providers out there, and you will choose one or more depending on your communication needs and wants. Often, services provided software applications for communication. Here is your gate to discovering about VoIP service, service providers, software and solutions.
VoIP vs. IP Telephony - Most people use the terms ‘Voice over IP’ (VoIP) and ‘IP Telephony’ interchangeably, equating one to the other. What’s the difference between the two, if there is any?
IPv6/IPng - IPv6 is a new and improved version of the IP protocol. In this article, you will learn what IP is, what its limitation is, and how this has led to the creation of IPv6, of which there is also a brief description.
Mean Opinion Score (MOS) - Mean Opinion Score (MOS) gives a numerical indication of the perceived quality of the media received after being transmitted and eventually compressed using codecs. MOS is expressed in one number, from 1 to 5, 1 being the worst and 5 the best.
Getting Started With VoIP - Once you are aware of the benefits VoIP can bring to your communication experience, you are very likely to decide to get started with VoIP, or at least give it a try. So what next? In this piece of content, we see the different things you need to have and do to get started with VoIP
How Does VoIP Allow Calls Between IP Networks And PSTN? VoIP works on IP networks and the PSTN uses landline networks with phone numbers. How can these two different technologies cohabit so well to make voice conversations from your phone or IP phone to any landline PSTN or mobile phone. It is all the work of address translation.
IP Routing - Routing is the process during which data packets are forwarded from one machine or device (technically referred to as a node) to another on a network until they reach their destinations.
IP Packets - IP (Internet Protocol) Packets are structure that carry data along over an IP network like the Internet. An IP packet consists of a header, a data payload and a trailer.
TCP - Transmission Control Control. TCP is one of the most important protocols on the Internet and it works in pair with IP (Internet Protocol) to make the TCP/IP suite, which is responsible for providing reliable data transmission over the Internet.
IP Addresses - What is an IP address and how does it work? An IP address is a unique address used to locate and identify a device over a network. That device can be an electronic device, a computer, a server, a router or even an IP phone. It is the addressing used for the transmission of data packets over a network working with the IP protocol.
IP Protocol - What is the Internet Protocol (IP) and how it works. This article talks about the protocol, IP routing, voice and IP, the TCP/IP protocol suite, IP packets and IP addresses.
QoS and VoIP - Quality of Service is an important issue in VoIP service provision. QoS is the differentiation between different types of traffic and classes of service such that one is favored over the other in terms of bandwidth utilization. In VoIP, QoS considerations favor voice traffic.
How to pronounce VoIP? How is VoIP pronounced, V.O.I.P or voyp?
There are a number of factors that directly affect VoIP voice quality, namely bandwidth, your equipment, the location of your hardware, weather conditions and compression algorithms. Here is how you can try and get decent VoIP voice quality.
Voice signals in VoIP calls are encoded into digital data, which are compressed so as to make it less bulkier for transmission over the Internet. The software used for compression are called codecs.
Here is a list of the most common codecs used in VoIP for voice encoding and compression, with comments.
VoIP Codecs - A codec is al algorithm used to encode and compress voice signals into digital data, thus making it lighter for transmission over the Internet. VoIP uses codecs for voice transmission.
There are problems attached to VoIP, along with the tremendous benefits it offers. While these benefits outnumber VoIP disadvantages, you should be aware of the VoIP pitfalls as a user, so that you have a better VoIP experience.
What is VoIP? VoIP stands for Voice over Internet Protocol. It is also referred to as IP Telephony. It is another way of making phone calls, though the ‘phone’ part is not always present anymore, as you can communicate without a telephone set. VoIP is especially popular with long-distance calls.
Why should you choose VoIP? What are its advantages and how does it make voice communication better and cheaper? Here is a list of advantages VoIP offers over regular PSTN phone.
There are three ways in which you can make a VoIP connection: Computer to computer, phone to phone and computer to phone or vice-versa. Let's see these in more details.
Difference between circuit switching and packet switching. What are switching and routing, and what are packets? Learn how packet switching makes VoIP better.
You can make VoIP use a great experience for your personal life and your business by making use of the different and amazing features available with VoIP.
