the message gets broken into small data packets.

It was designed in 1878 in order to send telephone calls down a dedicated channel.

• This does not necessarily mean that they seek out the shortest route. Each packet may go a different route from the others.

• This channel remains open and in use throughout the whole call and cannot be used by any other data or phone calls. 

• The telephone message is sent all together; it is not broken up. 

• It is any continuous signal for which the time varying feature (variable) of the signal is a representation of some other time varying quantity, i.e., analogous to another time varying signal. 

• Uses discrete or discontinuous values to represent information.

The message arrives in the same order that it was originally sent.

• These packets are sent out from the computer and they travel around the network seeking out the most efficient route as circuits become available. 

It uses continuous range of values to represent information.

PSTN stands for _______

Using underground copper wires, this legacy platform has provided businesses and households alike with a reliable means to communicate with anyone around the world for generations.

A method of converting analog audio signals to digital data packets (IP packets) that can be transmitted over the internet (via Internet Protocol) rather than via the Public Switched Telephone Network (PSTN).

PBX stands for ________

• It is also known as:

  • Internet telephony

  • Broadband telephony

Broadband phone service.

VoIP stands for ________

ATA stands for _______

• This will connect directly to the router of the user and have all the hardware and software necessary right onboard to handle the IP call including an inbuilt analog to digital converter.

• It allows the user to connect a standard phone to his/her Internet connection

It is an application software installed on a networked computer.

• Instead of having the standard RJ-11 phone connectors, this kind of ways to use VoIP have an RJ-45 Ethernet connector.

• This is an easiest way to use VoIP and it helps in making VoIP communication between two computers.

• Specialized phones look just like normal phones with a handset, cradle and buttons.

• The user does not even have to pay for long-distance calls (international calls)

This is the most simplest and common way to use VoIP facility. Basically an analog to digital converter which has the added capability to packetize digital data.

• It's a technology that allows you to make phone calls over an internet connection instead of over standard telephone lines.

• It uses an internet connection. Have an RJ45 port for an ethernet network cable

• It uses a phone line connection. Has a standard RJ11 phone port that uses a phone cable.

SIP stands for _______

•  It is an application that you download and install on your computer, tablet, or smartphone that enables you to make phone calls over the internet. Basically it's software that allows your devices to act like a phone.

• Realistically you really don’t need a VoIP phone because you can still use a landline instead. But you would have to use a special _______ where you would plug your landline into the phone port and then from your router or switch you would plug a network cable into the internet port.

• If you don’t want to even use a hardware phone, you can use what's called a __________.

• In order to use VoIP, you need to have:

a VoIP phone

• You would plug in the phone into your router or switch using a network cable, sign up with a VoIP provider, and then once that's complete, you can now make phone calls over an internet connection.

• VoIP also known as: 

Which is true about PSTN?

Which is true about INTERNET?

• It is the traditional circuit-switched telephone network. This is the system that has been in general use since the late 1800s.

______ phones are widely used and generally still accepted as a standard form of communication. However, they have seen a steady decline over the last decade.

• Using underground copper wires, this legacy platform has provided businesses and households alike with a reliable means to communicate with anyone around the world for generations.

• Before VoIP, people would make phone calls the old-fashioned way, which is by using traditional landlines where communications use PSTN or Public Switched Telephone Network.

The way a VoIP call is initialized is by using a protocol called ________

• After the connection has been made, as you speak into the microphone, your voice is converted from an analog signal to a digital signal using a technology called ______

RTP stands for?

• That digital signal is encapsulated into small chunks called (1)_______. This is done by using a protocol called (2)_____, which stands for Real-Time Transfer Protocol, which is a standard protocol for the transmission of audio and video data over a network.

• The data packets will then travel across the internet using UTP and then will route the data packets to the person you are calling.

• Once the data packets arrive, it'll reassemble those packets so the recipient can hear and understand your message.

• Whenever you want to make a phone call using a softphone, you would just pick up the receiver and then dial the number of the person you want to talk to, just like a landline.

•  if you're using a soft phone, you would just open up the application and then type in the number.

• It is similar to how DNS works, where domain names such as google.com is mapped to an IP address.

• One of the main things that SIP does is mapping phone numbers to IP addresses.

• A. The way a VoIP call is initialized is by using a protocol called SIP, which stands for Session Initiation Protocol.
  B. So when you dial a number, SIP will find the matching IP address of the recipient to locate and connect the call.
