Busting myths on digital phone lines

The Public Switched Telephone Network (PSTN) will be switched off in the UK on 31 January 2027. This means businesses must switch from traditional phone systems to digital phone lines now

Digital phonelines use a different type of technology to make phone calls — such as Voice over Internet Protocol, or VoIP. Instead of relying on physical, copper lines, VoIP transmits voice calls over the internet by converting the audio at one end of the connection into digital data packets, which are transmitted to the other end of the connection and are converted back into audio files. They use internet-connected devices rather than desk phones to make calls.

So, what are some common misconceptions around digital phone lines?

Myth 1 — VoIP offers less reliability and poor call quality


While this may have been the case when internet-based calls were first developed, the technology has significantly evolved since then and VoIP delivers calls with:

• Crystal-clear audio
• No lag or interference

It’s important to note that, as calls are held over the internet, your business broadband quality directly impacts calls, so a reliable internet connection, like full fibre broadband, is essential to making VoIP a success.

The breadth of the digital phone service also means that VoIP is more reliable than the PSTN. Calls are connected through several data centres across multiple locations, meaning that an outage in one area won’t affect VoIP services

Myth 2 — VoIP is more expensive

Cost savings are one of the main benefits of switching to digital. VoIP phone systems are priced on a per-user basis and are easily scalable if your business is going through a quieter or busier period.

You can increase or decrease the number of lines that you pay for super quickly, which is particularly useful for businesses with seasonal peaks, or those expanding to a new location. You also don’t need a bunch of new technology — all that’s needed is an internet-enabled device and a broadband connection.

VoIP also allows you to save money on your comms setup by implementing a unified communications (UC) strategy. UC combines all comms channels:

          • Telephones
          • Instant messaging
          • Emails
          • Video conferencing
          • File sharing

VoIP applications can be accessed from a range of devices, whether that’s a tablet, desktop or mobile, but it appears as just one phone number for business continuity.


Myth 3 — PSTN migration is complex and longwinded


Migrating to VoIP is not complex if businesses opt for a hosted solution. Hosted VoIP systems involve working with a provider, like Crystaline, on an ongoing basis, to manage installation, setup and troubleshooting.

Working with a communication technology partner helps to take the headache out of the switch as you’re provided with ongoing technical support protected by a service level agreement. And if you happen to already have VoIP-ready devices, businesses just need to download the app of their selected VoIP system, ensure the phone is connected to the internet and it’s ready to go.

Myth 4 — making calls over the internet isn’t secure


Digital phone lines are as secure as the IT infrastructure of a business, since they are made within an internal system. For example, the Vodafone Business UC with Ring Central system includes an authentication feature to ensure only authorised users have access and is encrypted to safeguard data and communications.

This prevents calls from being re-routed outside of an organisation and stops hackers from infiltrating the system to protect against third-party access to business data.

    Myth 5 — businesses need a new phone number for VoIP


    While a new number is an option when switching to VoIP, it’s certainly not essential. If you’re happy with the simplicity of your current contact methods, you can stick with it.

    What’s more, with VoIP calls, you can use the same number on several devices. As long as the app is installed, each employee can be contacted on the office number remotely from their mobile.

    This helps businesses by:

    • Ensuring they never miss a call as employees can receive a call from anywhere, on any device.
    • Supporting remote working, to prevent clients or customers feeling deterred from contacting their providers.
