- VoIP is a popular technology that allows a person to make a phone call over an internet connection.
- It’s used by companies of all sizes all around the world for both internal and external communications.
- The market is flooded with options, but a few of the best are RingCentral Office, Nextiva, and GoToConnect.
Voice over Internet Protocol (also known as IP telephony) is a method of delivering voice communication and/or group multimedia activities over a computer network – most notably the Internet.
Since its inception in the late 1990s as an alternative to the standard public switched telephone network (PSTN), VoIP has grown exponentially to billions of daily users worldwide. Companies of all sizes – from sole proprietorships to SMEs and large enterprise-level organizations – use VoIP to facilitate collaboration between remote workers, keeping different personal and internal teams connected in a flexible, cost-effective way.
The VoIP marketplace is a crowded one, and the technology is in a state of constant change. This guide will explain the basic premise of the technology, outline the core functionality and help you make an informed decision on what provider to choose from the hundreds of VoIP solutions available.
How Does VoIP Work?
Just like any other interaction on a computer network, VoIP works by the transfer of information from point A to point B. Analog voice calls are converted into ‘packets’ of data that travel across the Internet.
VoIP calls can either be delivered using a telephone handset that facilitates VoIP traffic by connecting to a computer network or made directly between two computers operating specialized VoIP software through the use of standard computer microphones and speakers – commonly known as ‘softphone’ technology.
Business also make use of technology known as ‘unified communications’ that incorporates voice calls, video conferencing, group conferencing and instant messaging.
Why Is VoIP Better?
VoIP holds numerous advantages over standard PSTN telephony services.
VoIP services are module based – businesses can add or subtract telephony services or purchase additional lines on a per-user or per-site basis. Standard PSTN services require the installation of physical infrastructure to accommodate extra lines and features.
PSTN networks usually require the purchase of dedicated lines per extension. VOIP services deploy this feature as standard and adding an extension to an existing service is usually just a cost consideration, rather than a hardware change.
Softphone platforms are designed to incorporate multiple forms of communication such as conferencing, chat, and webinars.
Call Routing and Forwarding
VoIP platforms allow you to categorize incoming calls and route them around your company based on variables such as customer type and staff availability, allowing you to work smarter with varying workloads and the real-time demands of your operation. Calls can also be forwarded to cell phones (or any other Internet-connected device) to ensure that your customers and staff are connected whatever the circumstances.
In the modern workplace, data is king. Integrated VoIP platforms offer a myriad of ways in which to interpret call data and ensure your organization is working as effectively as it possibly can when it comes to resource allocation and staff performance metrics. Call data can be displayed in real time on dashboards to drive performance or saved to management reports to inform broader staffing and resource strategies.
Auto attendants act as a virtual switchboard, funnelling calls to the correct agents based on a set of pre-defined parameters, ensuring that your customer’s queries are being dealt with by the right people, in the shortest amount of time. Auto attendants are adjustable in real time and can be configured to accommodate hundreds of agents across multiple sites. Companies can either delegate the maintenance of auto attendants to their IT/telephony provider or do it themselves to exercise granular control over call routing throughout the organization
Usually offered as an add-on, call recording captures voice data in the form of standard telephone calls, and saves them in a secure online repository for training, compliance and legal purposes. Staff can be granted access on a per-user basis, and call lists can be searched via multiple variables, such as call date/time, receiving agent, telephone number or source organization.

Choosing the Right Provider
Choosing the right VoIP provider for your business can seem like a daunting task. Providers offer the same underlying set of features and it can be difficult to differentiate prospective partners in what is a perpetually crowded marketplace.
Before you start to shop around, think about what it is that you need from a prospective VoIP platform, based on the following:
Work out how many people will need to use the platform within your organization, what numbers they need to call (local, national, international) and how far your budget can stretch within a per user, per month pricing model.
Consider what features your staff need in order to carry out their roles to the best of their ability. Do they require call recording? What are their video conferencing requirements? What kind of collaboration tools do your internal teams need?
The first step will be to decide whether or not to opt for physical handsets, or to operate via a softphone platform that takes the form of a desktop/smartphone application. Do some research into what the switching/routing requirements are of different platforms, and whether you’ve got the expertise to be able to configure VoIP equipment yourself or if that job needs to be outsourced.
