Why is Everyone Switching to The Cloud?

End Of Life For ISDN 2019

All ISDN lines in the UK are connected to the BT network, and so this will affect millions of businesses across the UK.

As of August 2013, it was estimated there were around 3.2 million active ISDN lines in the UK. By 2025, they will all need to make the switch to an IP network.

SIP (Session Initiation Protocol) is the replacement for ISDN. It allows you to send multimedia (voice, instant messaging, video calls etc.) using the internet. SIP has many advantages of ISDN, including greater flexibility and lower costs.

It may seem like a long time off, but it’ll be here before you know it.

Start future proofing your business today by moving to a cloud-based phone system.
