Beat the BT ISDN
Switch Off.

BT are switching off the PSTN and ISDN networks for good, starting with a cease of new supply by 2023 and moving to a full migration to IP before 2025. 

The BT switch off could affect thousands of businesses in the near future, especially those unaware of BT’s intention to phase out of technology. Traditional phone lines are a legacy technology with high maintenance costs and many drawbacks.

In Short, before 2023 you will no longer be able to order ISDN services and by 2025 you must have totally upgraded to IP telephony to avoid interruption to your telephone services.

Save up to 82% when you upgrade to SIP Telephone Lines.

SIP Phone Lines and Cloud Hosted Phone Systems are now rapidly replacing older, traditional ISDN and PSTN services. 

Our IP solutions are sold UK wide where they have proven to be ultra reliable and both cheaper and more flexible than traditional digital or analogue phone lines that are gradually being made obsolete. There is no reason why you shouldn’t consider upgrading now to maximise both savings and benefits.

Millions of people already have first-hand experience of VoIP through services like Skype which was originally created to allow free or low-cost calls to be made over the internet. Such services have grown in sophistication & reliability and are now widely used on a daily basis by UK businesses as a replacement for ISDN and PSTN.

Upgrading to SIP is more cost effective option.
