Make sure your teams and customers stay connected and collaborative, with Cloud VoIP

A Very Brief History of Telephony... (expand)

Before Hosted VoIP, back in the late 1800s phone systems began with PSTN (Public Switched Telephone Networks), which ran analogue voice signals through copper lines. This system served its purpose for the next 100 years or so, at which point ISDN (Integrated Services Digital Network) was introduced in the 1980s. ISDN used the same copper lines but it was able to send digital signals as well, resulting in better call quality and the potential to use more advanced data features.

But the issue with both of these systems is that they require costly infrastructure to be housed on-site, including PBX (Private Brach Exchange) systems, which are essentially a private telephone exchange housed within your company premises. They’re also inflexible and limited in terms of the features they offer, and certainly not set up for remote working.

Nowadays, in a world of rapid and continuous change, a telephone system that allows your teams to stay connected from any location is a must-have.

Replacing the now dated PSTN and ISDN networks is SIP Trunking (Session Initiation Protocol), which allows you to make telephone calls through the internet via Hosted VoIP systems (Voice over Internet Protocol). With a decent internet connection, these cloud-based telephony systems deliver an enriched communications experience and allow your people to remain effective no matter where they are.

And importantly, BT’s ISDN and PSTN switch-off is set for January 2027. So if you’re using traditional technology for your phone systems, its time will soon be up.

What is Cloud VoIP?

A cloud-based VoIP phone system lets you make and take calls using an internet connection, by converting analogue sound into a digital format. In a sense, it’s much the same as using online tools such as WhatsApp or Skype to make calls.

Cloud VoIP or dedicated Hosted VoIP provides all the capability of an advanced on-premise business phone system, without the complex and pricey infrastructure. All the hardware and software is managed by a third party instead, through a cloud telephony platform – making CapEx a thing of the past. Aside from a handset or headset, an internet connection is all that is required. You use a simple web interface to make calls in a few clicks of a mouse.

Scalable, secure and able to deliver a superior customer experience, business VoIP telephony solutions don’t just deliver conventional voice. They give businesses the flexibility to take and make calls from anywhere; monitor and manage phone networks in real-time; and benefit from advanced and easy to use IP phone features such as call recording, auto-attendant, call queuing, instant messaging, hunt groups, conferencing and smart collaboration tools.

And as it’s cloud-based, you can rest assured you’ll always have access to the latest features, rather than risk being stuck with outdated on-premise systems.

Microsoft Teams Integration

Many organisations are accelerating their plans to build a more agile working environment for their people. A Hosted VoIP system can also allow you to integrate additional tools into your digital transformation strategy.

Microsoft Teams is often a critical component of that transformation – enabling people to communicate and collaborate, whether they’re in the office, or on the move. Connecting your Hosted VoIP capability with MS Teams gives you a streamlined and unified approach to communication.

Your remote staff will be able to handle calls as if they were at their desks, meaning you can provide the same responsive service to your customers without complex and rigid call forwarding processes. They can also access key files and documents from the MS Office 365 suite during a call, making them more productive and further improving customer satisfaction.

A Microsoft Teams Phone Integration can connect seamlessly into a cloud telephony platform, giving your employees the ability to make an external call direct from MS Teams, making it a highly cost-effective alternative to the restrictive Microsoft calling plans and charges. This means you save money while getting more from your investment in MS Teams.

The Benefits of VoIP

Greater scalability

Add users (seats) and features as and when you need them, only paying for what you actually need, not what you think you might need in the future.

Increased mobility

Your team will be able to stay connected to your customers and each other, no matter where they are. No need for complicated call-forwarding when your team works remotely.

Business continuity as standard

Should maintenance, disruption or a disaster cause an outage, you can divert calls to another location in a few clicks, and get back up and running in no time.

Cost effective

Costly capital expenditure and line rental is no longer an issue. Everything is hosted in the cloud.

Microsoft Teams integration

If you use MS Teams across your business, as many do, a good Hosted VoIP platform will allow you to make and receive calls directly from Microsoft’s platform.

Monitor uptime and usage

You’ll be able to easily check the status of your phone lines and availability of your colleagues wherever they are.

Choose multiple phone numbers

Regardless of where you teams are, you can pick and choose relevant numbers for both staff to use and customers to call in on. You can also switch different teams or offices to chosen numbers as you wish.

Future proof

An on-premise phone system can quickly become outdated. Hosted VoIP will deliver the latest features to you as and when they’re released – no need to keep upgrading your systems.

Relocate with ease

If you move office or build additional teams in new locations, you can relocate your hosted VoIP system in no time – plus you can keep all your old numbers.
