[•] The Difference between hosted IP PBX and non-hosted IP PBX
What is VoIP?
Voice over Internet Protocol or VoIP is a term used in delivering voice communications through the use of an IP or Internet Protocol. It has become widely popular because of the minimal cost a user can accrue from those traditional telephone networks.

VoIP Benefits | Benefits of VoIP
Since we already know what VoIP is, we also need to know how it can benefit us as users. Here are some of the benefits of VoIP:

1. Cost Efficiency

Since VoIP phone uses the internet to make phone calls, it is really cost efficient. Users of VoIP usually save 50% to 80% in their phone bills as compared to using the traditional phone. It may not be that much for individuals but for large organizations and companies these means saving thousands of dollars per month. Cost efficiency is the first thing you get as one of the benefits of VoIP.

2.Flexibility and Portability

VoIP Benefits also include integration capabilities. VoIP phone can be integrated with other computer applications such as email, e-fax, web conferencing and some have features like Video over Internet Protocol. You can use VoIP to make phone calls while surfing, downloading, and chatting at the same time. You can bring your telephone number with you anywhere you go. If you have a VoIP hardphone or softphone, you just need a computer and an internet connection and you can start making and receiving calls anywhere and anytime. Wireless VoIP or wVoIP can even be used when there is a WiFi connection or hotspots.

3. Productivity Improvement

One of the benefits of VoIP is the increase and improvement of your business productivity. If VoIP is cost efficient and allows large organizations and companies to save thousands or even millions of dollars, it means that the amount saved can be utilized for other productive purposes. Other organizational processes and functions can gain more finances from the savings which leads to more productivity.

4. Features

Features are always looked for in almost every product purchase and VoIP benefits are not an exception. While traditional phone companies ask for charges for extra features such as call waiting, voicemail, forwarding, Caller ID, and etc, these features are made a standard in VoIP phones. This means that you don’t have to pay extra charges for such features because they’re already part of the standard VoIP phone package.

5. Scalability

The VoIP phone system is highly scalable. It is very easy to install and use, very user-friendly even for those who are not very good with computers. New components can be added easily without having too much trouble. Voice will be converted to data based on software rather than hardware as opposed to traditional phones makes it easier to maintain the system.

6. Voice Clarity

A few years ago, talking through VoIP was like talking through a tin can with a string attached to another tin can. Calls were distorted, lagging and many time dropped. Well, times have changed and with new VoIP technologies the call clarity is better than ever.

What are VOIP Phones?

Voice over Internet Protocol or VoIP is a term used in delivering voice communications through the use of an IP or Internet Protocol. It has become widely popular because of the minimal cost a user can accrue from those traditional telephone networks.

Why VOIP?
Voice Over Internet Protocol or VoIP

is the term used in delivering voice communications through the use of an IP or Internet Protocol. It has become widely popular because of the minimal cost a user can accrue from those traditional telephone networks. It uses internet technology to allow voice data to travel therefore enabling the user to create phone calls.



The ultimate reason why people shift to a VoIP phone system is its cost reduction. Because it is digital and uses the technology, attributing features are more compelling and alluring. VoIP providers are growing in numbers that you may not need to worry for choosing what’s best for your need.

What is VOIP Gateway?

A VOIP Gateway or PSTN Gateway is a device that converts telephony traffic into IP for transmission over a data network. They are used in 2 ways, firs is by converting incoming PSTN/telephone lines to VoIP/SIP and second is connecting a traditional PBX/Phone system to the IP network

A VoIP uses a high speed broadband internet connection for routing telephone calls different from the traditional switches and fiber optics alternatives. This functionality provides higher efficiency and minimal cost for communication consumption of users. It is also a combination of an internet phone and conventional phone performance into a single service.

What is SIP?
Session Initiation Protocol

is an IP telephony signaling protocol used to determine, amend, and terminate calls made by VoIP telephones. It was developed by the Internet Engineering Task Force (IETF). SIP, Session Initiation Protocol is an IP telephony signaling protocol used to establish, modify and terminate VOIP telephone calls. SIP was developed by the IETF and published as RFC 3261 SIP describes the communication needed to establish a phone call. The details are then further described in the SDP protocol. SIP has taken the VOIP world by storm. The protocol resembles the HTTP protocol, is text based, and very open and flexible. It has therefore largely replaced the H323 standard.

What is SIP Trunking?

  • SIP Trunking reduces or eliminates the costs associated with the purchase of hardware media gateways.
  • SIP Trunking also reduces or eliminates the costs associated with the ongoing support and maintenance costs of hardware media gateways.
  • SIP Trunking reduces the recurring costs of separate PSTN and data circuits (some dedicated to voice, some to data).
  • SIP Trunking eliminates the over-subscription of voice channels based on business requirements.
  • SIP Trunking supports multiple forms of communication including video and instant messaging allowing for greater levels of user presence.
  • SIP Trunking utilizes DID’s (Direct Inward Dials) that allows each employee to have their own phone line. This increases the flexibility and implementation of call control and dial plans.
  • SIP Trunking improves the call quality of voice based IP communications because each SIP Trunk is a dedicated “channel.”
  • SIP Trunking reduces toll charges from SIP origination/termination services to the PSTN for external long-distance and local access calls.
  • SIP Trunking allows for the selection of a single SIP Trunk which increases the flexibilty and ease of adding, subtracting, or changing a line.

What is PSTN?

This is the acronym for Public Switched Telephone Network.

Traditional telephone system that makes use of copper wires to transport analog voice data makes up a PSTN network. This is the kind of telephone system majority of the world’s population used when VoIP was not yet introduced to cut on costs of communication bills.

PSTN is also referred to as Plain Old Telephone Service (POTS). This is a combination of the circuit-switching telephone networks and Alexander Graham Bell’s invention. Currently, PSTN is on its way to becoming obsolete because of the digital telephone system that has been proven of to be effective with its many features it gives to an end user unlike the old PSTN

What is VOIP Codec?

A VoIP codec is used to convert analog signals to digital and another similar codec located at the opposite side of the communication converts the digital signals back to the analog. Codecs are also used to encode voice for transmission across IP networks.

What is IP PBX

An IP PBX (Private Branch Exchange) is used to support a VoIP also referred to as VoIP PBX. This can support internal and external communications. Internally, it uses VoIP to communicate with its co-connected PBX phones. On the other side, its external use considers routing calls to the world. Click here and see the benefits of an IP PBX

How does IP PBX Work?

A VoIP Phone System / IP PBX system consists of one or more SIP phones / VOIP phones, an IP PBX server and optionally includes a VoIP Gateway. The IP PBX server is similar to a proxy server: SIP clients, being either softphones or handset based VoIP phones, register with the IP PBX server, and when they wish to make a call they ask the IP PBX to establish the connection. The IP PBX has a directory of all phones/users and t eir corresponding SIP address and thus is able to connect an internal call or route an external call via either a VoIP gateway or a VoIP service provider.

What is SIP Phones?

Session Initiation Protocol is an IP telephony signaling protocol used to determine, amend, and terminate calls made by VoIP telephones. It was developed by the Internet Engineering Task Force (IETF).

SIP, Session Initiation Protocol is an IP telephony signaling protocol used to establish, modify and terminate VOIP telephone calls. SIP was developed by the IETF and published as RFC 3261

Cost-Cutting your Phone Bills?

On the average, almost $5000 dollars are spent over telephone bills using the traditional telephone system while at an average starting rate of $30 using VoIP. Voice over Internet Protocol is the ultimate solution to many queries pertaining into how cost cutting can truly help you and your business. Start it with changing the way you communicate into more effective and better sounding features with VoIP.

Now you can eradicate your phone lines. With VoIP services, cut off your traditional phone service through your local telephone company and let your broadband internet connection do all the workloads for you. For residential users, this way will help you save an average of $40 a month and thousands of dollars for business entities.

This will also be a guarantee that you save on your long-distance calls charges. A number of end users both for business and residential units that accrue a pay-per-minute scheme over a long-distance telephone call. With VoIP, see how you can reduce these payments with packages available for you. Through the integrated Computer Telephony Integration (CTI).

How IP Phone works?

When we say IP Phone we are talking about the unit of the phone itself (handset type/hardphone) or the softphone(software-based). IP Phone works by connecting through the RJ-45 Ethernet connector to your router. By doing this, you simply get an connected through the internet and with the necessary settings in the software, you can now make phone calls through the internet. The softphone is different but works in the same way. Since it is a software type of IP Phone, you don’t need to plug anything, you simply install the software, configure it and start making phone calls through the internet.

What is VoIP Phone?

VoIP Phone is actually the same with the IP Phone. It is the device, either software or hardware that allows you to make telephone calls through the Internet. Hardware types of VoIP Phones are called handsets or hardphones while software type of VoIP phones are called softphones.

How VoIP Work?

When we say “VoIP” we are talking about the technology itself that allows voice calls to be done over the internet. To simplify things, it works by converting your voice from analog signal to digital data which is then disassembled over the internet, and reconverted back to analog signal on the other end. The protocol used to transmit voice signals over the internet is called Voice over Internet Protocol (IP) or simply VoIP.

What is VoIP Technology?

VoIP Technology is anything that is involved and essential in order for VoIP to function. It includes but is not limited to hardware (handset/hardphone, RJ-45 Ethernet socket, VoIP gateway, IP PBX etc), software (VoIP softphone, VoIP Apps, SIP, IP PBX), computer and internet. VoIP Technology is anything that makes it possible to make phone calls over the internet.
