What is an IP PBX?
An IP PBX is a phone system that makes and receives calls over the Internet. Instead of using old analog or digital technology to move phone calls, an IP PBX uses Voice over Internet Protocol (VoIP). This means your phone system is no longer tied to physical phone lines, which are expensive to maintain, but instead can transmit voice data over your existing internet connection. This reduces the cost of phone systems and makes them easier to maintain.
Connecting an IP PBX to the Telephone Network
While an IP PBX replaces your old phone system, it still needs to connect to the Public Switched Telephone Network (PSTN), which is the old phone network that still connects most of the world. The PSTN doesn’t use VoIP, but there are two ways to connect to it from your IP PBX.
Use Specialized Hardware to Connect to the PSTN
To connect to the PSTN directly from your IP PBX, you need a device to translate between them. This is called a VoIP gateway and can be either a card installed inside the computer on which your IP PBX is running or a stand-alone device that communicates with your IP PBX via your office network and then translates the calls to the PSTN.
Subscribe to an ITSP who provides SIP Trunks
An Internet Telephony Service Provider (ITSP) is a company than maintains the equipment necessary to connect many hundreds (or thousands) of VoIP calls to the PSTN. You can buy a service from them called SIP trunking and connect your IP PBX to their data center over the Internet or through a dedicated circuit. You tell the ITSP how many simultaneous calls to the PSTN you want, and they will set-up the SIP trunks to carry that much traffic.
A Phone vs. an Endpoint
In the world of VoIP, you often hear the word ENDPOINT, rather than the word PHONE. Endpoints can be phones, cameras, or applications running on a smartphone, speaker, and many other kinds of devices. A phone is typically thought of as a device that sends and receives calls. Endpoints can support voice, but also many other types of communication, like texting and video.
Options when deploying an IP PBX
IP-based phone systems have given businesses the flexibility to choose the deployment option that works best for their organization. Now, businesses can select their communications solution based on a plethora of options, such as budget, IT capabilities, physical space, and more.
This option outsources the operation of the IP PBX to a service provider. The only equipment on-site at your office is the phones. The phones communicate with the service provider over the Internet or a dedicated WAN. In most cases, you pay a flat fee per user, so communication costs are moved from a capital expense to an operating cost. It also means that you no longer have the responsibility of maintaining and upgrading the system. This is all shifted to your provider. You never have to worry about your phone system becoming obsolete because it will be continually up-to-date. If you have a seasonal business, it is also very easy to change the capacity and number of users of the system based on your specific need.
Premise-Based IP PBX
With an on-premise solution, the IP PBX software is installed onto a dedicated server in your office. The IP phones connect to the IP PBX over the office LAN. You must decide if you are going to use traditional phone lines to connect to the PSTN or use an ITSP. If you select the former, you must decide between internal cards or an external gateway.
With a premise-based IP PBX, you are in total control of the implementation. For some businesses, especially those dealing with sensitive or secure information (like call recording), it may be a regulatory or security requirement to keep everything on-premise.
Are you search for an IP PBX, you will often hear the term Unified Communications or UC. UC is the next generation of IP-based telephony. It is a communications system that combines, or unifies, all the ways a business communicates into one platform. These include voice, chat, email, fax, instant messaging, and texting (SMS/MMS). UC enables a user to switch between these modes of communication easily, enhancing productivity and increasing collaboration.
