The short answer: VoIP converts communications over an IP network into packets of data, sending those packets out over the network. Because of the way the data is routed, you do not need a traditional phone in your home or business in order to use VoIP as calls are directed over the internet.
The answer above is technically correct, but there is more to the story if you dig deeper.
VoIP gives the user the ability to combine Internet and phone services. It is easier to scale because of its infrastructure, and it is compatible with many of the new features that are being created for communication clients by third-party app developers.
VoIP functions over an IP network. All data that comes through the network is finally stored in the cloud. All settings associated with this data are immediately accessible through a digital user interface application or universal online dashboard.
The dashboard for a VoIP network gives the users access to data that they store there, including client information, contacts, and phone numbers. Users also have the ability to add new phone numbers and set up call settings. All of this functionality is available in a traditional office or on mobile hardware.
This is the explanation from a customer-facing perspective. If you want a deeper technical understanding of how VoIP works, read on. The description below will help determine if you have the specs to use a VoIP network in your current business environment.
VoIP systems do not use any sort of hosted PBX system or any other kind of PBX system for that matter. PBX stands for ëPrivate Branch Exchange,í and it means a telephony system runs from a private system instead of the cloud. VoIP functions across your Local Area Network (LAN) and moves data to the servers that are owned and managed by your provider.
If you have a digital device ñ like a laptop, a phone or a tablet ñ you can begin the process of VoIP routing. These devices are known as ëSIP-enabled,í (which stands for System Integrity Protection). The VoIP system can connect to a Public Switched Telephone Network (PTSN) or a SIP device. Before this happens, the data must travel through the router that is connected to your LAN network.
The router is a very important part of the day to day use of a VoIP device. The traditional telephone system connects your phone to the system through a copper line that is also likely taken through a server that may be in your office or off-site.
From there, the entire communication occurs in the cloud. Because the data that you send does not stay in your proprietary reach for very long, the need to create an infrastructure on-site is greatly reduced.
In a VoIP system, your router will connect to the Internet platform that you have chosen. It will access the IP network that your ISP (Internet Service Provider) works with. At this point, your VoIP platform has the ability to access the majority of digital device types for the purpose of communications.
VoIP is truly amazing because of its instant adaptability and device flexibility. For example, you choose from a bevy of mobile devices, but you can also use softphone enabled desktop devices such as your home computer or tablet.
A major reason that VoIP is gaining traction in the world of business is its ability to give its clients remote access to central hub offices. Many offices are transitioning to work schedules that are not quite so traditional and requiring more travel from their employees. With VoIP, these companies are able to stay in business while expanding their reach and ability to operate across the world.
What is SIP Trunking?
The SIP is another vital piece of the VoIP puzzle. You may be a part of a company that wants to keep an on-site PBX for some reason. If so, SIP Trunking is likely a part of your infrastructure. In essence, SIP Trunking then becomes the direct pathway to your VoIP provider, sequestering its own space within your infrastructure.
SIP trunks collect the information that comes from the service provider PTSN. It funnels the data in the same way as other VoIP connections. Hardwired into the server that is likely right beside the PBX, the trunk is actually a switch that filters your data as it funnels it through.
In many cases, it allows all of a companyís voice communications to move to a separate line. That line is fully dedicated to your company, only your data moves through it. In suh cases, the main LAN network would be 100% available for other business processes.
