Home / News / Common mistakes businesses make when switching to VoIP

Switching to Voice over Internet Protocol (VoIP) is an excellent way for businesses to modernise their communications, reduce costs and improve flexibility.

With the UK’s PSTN switch-off continuing to reshape the telecommunications landscape, more organisations are making the move than ever before. However, while the benefits are significant, a poorly planned migration can lead to unnecessary disruption.

Here are some of the most common mistakes businesses make when switching to VoIP – and how to avoid them.

1. Overlooking your internet connection

Your internet connection is the backbone of any VoIP system. Poor bandwidth, network congestion or an unreliable connection can result in dropped calls, poor audio quality and frustrated employees.

Before migrating, it’s important to assess whether your current internet connection is capable of supporting your expected call volume. Upgrading your broadband or implementing Quality of Service (QoS) settings can make a significant difference to call performance.

2. Choosing the cheapest solution

While it’s tempting to focus solely on price, not all VoIP providers offer the same level of reliability, security or support.

A low-cost solution may lack essential business features such as call recording, auto attendants, CRM integration or robust cybersecurity. It may also lack the setup required to scale with your business, holding you back at a time when everything should be working at its best. Instead, consider the long-term value of a solution that can grow alongside you.

3. Forgetting About cyber security

Like any internet-connected service, VoIP systems can become targets for cybercriminals if they aren’t properly secured.

Strong passwords, multi-factor authentication, network security and regular software updates all play an important role in protecting your communications. Working with an experienced IT provider ensures your VoIP platform is configured securely from day one.

4. Not preparing employees

Introducing a new phone system without adequate training can reduce productivity and lead to frustration.

Take the time to demonstrate new features, explain how the system works and provide employees with guidance before the switch takes place. A confident team will quickly take advantage of features such as voicemail-to-email, mobile apps and video calling.

5. Failing to plan the migration

A rushed migration increases the risk of downtime and service interruptions.

Creating a clear implementation plan, testing the system before go-live and scheduling the migration outside of peak business hours helps ensure a smooth transition with minimal disruption.

Make your VoIP migration simple
