ISDN Switch off
Future-proof your business
‍‍

Get ready for the 2025 ISDN switch off with SIP

As the ISDN switch off looms, businesses need to get their communications ready for the switch off date.

In 2023, ISDN reaches it's stop-sell date, so businesses using ISDN will not be able to add additional lines—so they'll need to covert to SIP Trunks.

In 2025, the entirety of the UK's ISDN will be switched off, which means that if your business is not using SIP, you will lose communications.

What happens if my broadband goes off?

If your broadband has an outage, so will your SIP Trunks. But don't worry. SIP Trunks can be instantly diverted to a backup number, such as a mobile. Alternatively Bytes Digital can provide 4G/5G backup solutions to ensure no downtime.

How much does SIP cost?

The cost of SIP Trunks vary depending on your businesses requirements. In general, with SIP, you only pay for the number of concurrent calls you need—so if you have 3 people on the phone, you might need 4 trunks for example (keep one spare for incoming calls).
