FAQ

Gamma Phoneline+ — Frequently Asked Questions

Common questions from small business owners looking to upgrade their traditional landline.

What is the PSTN Switch-Off and how does it affect my business?
BT Openreach is permanently turning off the traditional copper telephone network (PSTN and ISDN) across the UK. If your business currently uses a standard analogue landline plugged into a wall socket, it will stop working. Gamma Phoneline+ is the direct, digital replacement that uses the internet to make calls, ensuring your business stays connected.
Will I lose my current business phone number when I switch?
No, absolutely not. T2K VoIP will seamlessly port your existing local or national number over to the Phoneline+ cloud network. Your customers won't notice any difference, and they will continue to dial the exact same number they always have.
Do I need to buy a new desk phone to use Phoneline+?
It is entirely up to you. Many of our micro-business clients choose to use the Phoneline+ app on their existing iOS or Android smartphones, meaning zero hardware costs. However, if you prefer having a physical phone on a desk or shop counter, we can supply a compatible IP handset that simply plugs into your internet router.
What happens if my shop's internet goes down?
Because Phoneline+ is cloud-based, your calls are protected. If your local broadband fails, your desk phone might drop offline, but the Phoneline+ app on your smartphone will automatically switch to using your 4G or 5G mobile data network. Your business remains open and able to take calls without interruption.

Ready to Future-Proof Your Business Line?

Don't wait for the switch-off. Upgrade your traditional landline to Gamma Phoneline+ today. T2K VoIP makes the switch effortless, protecting your number and reducing your monthly bills.
