Voice communications are going digital. Gradually the backbone networks that support our phone calls are moving to fibre optics and digital handling of calls, and VoIP allows us to make low-cost calls over the internet.
As VoIP gains in popularity http://www.talktechdaily.com/infographic-landline-voip/, it’s easy to think that this is the basis of all new call technology. But in fact, there are subtle differences between VoIP and IP telephony and it’s important to understand what they are.
IP refers to internet protocol. Put simply this means using the hardware and software of an internet connection to provide communications. This can be for data, voice or video and it can allow you to share a connection for a number of different purposes.
VoIP uses IP as its carrier to make calls via the internet. However, IP isn’t restricted to calls, it refers to the whole infrastructure of digital communications.
Voice over internet protocol
VoIP is, essentially, a means of making voice calls over IP while adding user-friendly features to assist with call handling. VoIP is a set of protocols that allow you to make calls in a digital environment. This could be used internally within a local network, or over the internet to make calls to anywhere.
The most popular application of VoIP for business is to allow the use of an AZ termination provider such as https://www.idtexpress.com/blog/category/voice-termination/ in order to cut the cost of business calls to any destination.
In practical terms then, IP telephony is about digitising the communications network and about integrating it with other forms of communication. VoIP is the means of implementing this to allow people to make and receive calls either via a softphone application or via IP phone hardware. It can be implemented entirely in the cloud so you can do away with the requirement to have an in-house PBX system.
There are a number of advantages to this, for example, calls within your business – even to branch offices – can be made within the network at no cost. You can also have a central number for all of your locations and staff can be reached on their business number wherever they happen to be. This, plus features like automated call handling and voice mail, can give you the appearance of being a much larger business.
