Odds are you have heard this strange term before. VoIP stands for voice over internet protocol, which is essentially a flowery manner of claiming "hey, with this technology you'll run your phone service through the internet." The technology required for smart VoIP has been around for a whereas but it hasn't received very abundant attention till simply recently.
We heard some people wondering out loud whether or not dedicated VoIP hardware has become obsolete.
They understand why anyone might think PBX systems and physical phone handsets are going the way of the dinosaur. In the event you need to write a hot-button article on communication expertise that people will knee-jerk agree with, all without having to give the subject much thought, all you need to do is say "telephones are dead!" and leave it at that.
Because advances in technology has increased at this time for the past time, and also increase the use and speed of the international network increased by extension using VoIP, so consequently also increased the number of followers to this area, especially among small and medium enterprises, with the following basic reasons to use the Smart VOIP.
VoIP or Voice over Internet Protocol, has become a better, cheaper for business telephone communications. These systems use Internet connections instead of the BT network and therefore the costs are significantly reduced. It is an operator of internet telephony, smart VoIP services offered by the hardware and the necessary support to the company, in turn, pay a monthly fee. Contrary to the nature of the service a "phone" is not always necessary, as it is now possible to communicate without devices, (by the computer).
Optimizing your return from social media is one of the most important challenges nowadays. That is why quintly has created an easy to use tool that helps brands, agencies and media companies to track and benchmark their social media profiles in one central place. Only by looking at competitive data, you can differentiate your own performance from general market behavior and optimize what you are doing.
Here are the fantastic four programs you really need to use
Setting up your own PBX server used to be a huge hassle. After hours of scouring the internet, I finally have two Samsung Galaxy Note II phones making high quality calls using two separate Google Voice accounts over my own server! Because this uses data, you actually have unlimited calling in the United States and Canada using Google Voice. Unlike PBXes, you can talk to somebody for longer than an hour without being inconveniently disconnected. What's so great about setting this up is if you decide you don't want to pay T-Mobile $30 per month for service, you can cancel and still make unlimited phone calls with your real phone number provided that you have a Google Voice number using any WiFi connection! You can port your cell phone number permanently over to Google Voice for a one-time $20 fee.
While I don't hold a PhD in telephony, I have done enough research to be able to supply the first video tutorial aimed specifically at frugal Android users who want to get VoIP calls working on their phones. This is great for users who have low minutes on their cell phone plan (such as T-Mobile's 100 minute 4g plan for $30/mo) because once you're set up, you won't even use your carrier minutes. This method also allows HD G.722 16kHz (phone lines are 8kHz) calls to anyone else you put on your server.

Introduction
Telephone systems are not complicated if you understand how they work.
A Word on VoIP
VoIP is not a telephone system
PSTN
PSTN -- Public Switched Telephone Network is like the Internet, but for telephone communication
NADP -- North American Dialing Plan -- Is the system for routing telephone calls.
Central Office -- All telephone lines connect to a local central office
Trunk Lines
Every Trunk Line has a telephone number
A Trunk Line allows for 1 incoming or outgoing call. You can have far more telephones in a building then you have trunk lines.
Incoming
Trunk lines are setup in Hunt Groups. If the main phone number is busy
the call is automatically forwarded to the next number in the Hunt
Group
Incoming Hunt Groups are setup by your local telephone company.
Outgoing calls can be routed to use selected trunk lines. This in configured in your PBX.
PBX and Voicemail
The PBX routes telephone calls
The Voicemail system provides all audio messaging. (Voicemail boxes, Message Boards, and Auto Attendant Messages)
Stations
All devices that connect to the PBX are "Stations". This includes telephones, call boxes, intercom systems, etc.
There are 2 types of stations; Analogue and Digital.
Analogue
and Digital stations have to be connected to appropriate ports on the
PBX. An analogue phone cannot connect to a digital port and vice versa.
Almost
all fax machines and phones you buy at retail stores are analogue. If
your new fax machine does not work it may be because it's plugged into a
digital line.
Subscribers
Subscribers are users of the Voicemail system.
Subscribers do not have to have stations
Voicemail
ports are the number of connections to the Voicemail system at any one
time. This includes not just people retrieving their voicemail, but
also incoming calls that connect to Auto Attendant messages.
Final Thoughts
Be
careful before you touch! Most older telephone and voicemail systems
were administered using a phone keypad, NOT and computer interface. If
you mess something up it can be very difficult to rebuild a deleted Auto
Attendant or such.

Class Notes
Introduction
All telephone systems use the same basic concepts to route calls
Extensions
PBX's relate to everything as an extension. A station is an extension. An Auto Attendant is an extension, etc.
You
should create a range of extensions for use for stations and
subscribers, and a different range of extensions to be used for
administrative purposes (Auto Attendants, Hunt Groups, etc)
You can determine how many numbers make up an extension (2,3,4)
Call Paths
Call paths determine how an incoming call is routed.
A standard call path states that a station is rung 3 times, and then the call is routed to voicemail.
You can have call paths with 20+ steps.
Out Calling
Out
calling allows the PBX to route calls from the outside to outside
lines. A call from the outside can be routed to a cell phone.
Out calling requires 2 trunk lines (1 for the incoming call, and one for the outgoing call)
Out calling can be a HUGE security problem if not administered properly.
Incoming Trunks
Incoming trunk lines are programmed into Trunk Groups.
Individual Trunk Groups are pointed at a specific extension for incoming calls (Usually an Auto Attendant)
Multiple
businesses in the same building can use the same PBX by putting their
phone lines into Trunk Groups and then pointing the Trunk Group to their
Auto Attendant.
Auto Attendants
"If you would like Sales press 1"
The message for the Auto Attendant resides on the Voicemail System.
You
create an Extension, make it an Auto Attendant, point the message to a
Voicemail box, determine what will happen when users press number keys,
determine what happens if the user does nothing.
Hunt Groups
Are Extensions that when called ring a series of other extensions in order.
If the first extension in the hunt Group is busy, the next extension in the Hunt Group is rung.
Weighted or Smart Hunt Groups can route calls to extensions based on programmed parameters.
Call Groups
Call Groups are Extensions where numerous Extensions are rung at the same time when the Extension is dialed.
Outgoing Call Routing
You
can create Outgoing Trunk Groups based on whether the trunk lines have
local, long distance, or international calling privileges.
You can create codes to allow managers to be able to access any Outgoing Trunk Group.
Outgoing
Call Routing is based on the number of digits dialed, and whether those
digits match a pattern that allows the call to be routed to a specific
Outgoing Trunk Group.

Class Notes
VoIP Servers
VoIP Servers route calls like a traditional PBX
There are proprietary and Open Source versions of VoIP Server software
VoIP Clients
VoIP "phones" are all client computers
Hard Phones are computers made to look like traditional phones
Soft Phones are software that is installed on a computer so that the computer can be used as a phone
Gateways connect VoIP networks to the PSTN (Public Switched Telephone Network)
Protocols
VoIP Systems use protocols for servers and clients to communicate
SIP is a standards based protocol that numerous vendors use
Codecs are used to encode voice communication
Codecs determine the Sound Quality and the Bandwidth usage of a call
Most VoIP servers come with codecs that you can use without any extra fees. If you need better codecs they can be purchased
Network Latency and QOS
Network latency is the time it takes for data to get from point A to point B
Standard telephones have a latency of 45ms, VoIP can have a latency of up to 75-100ms.
QOS
-- Quality Of Service -- is a feature of networking equipment that
allows the equipment to prioritize network traffic based on what it is.
Unified Communications is the idea that computer programs and server should be able to work with telephone communications.
Before you go to deal with a voip service provider, there are some questions must be asked. This video shows best questions you should ask the provider.
