From the past to the future: how to make the move from ISDN to SIP

Organisations are changing the way they think about communications.

Today’s business climate calls for reliability, agility and flexibility. In order to deliver on these core goals, the tools companies need to communicate to their customers and the wider world must be future ready and fit for purpose.

However, that is not always the case. Many companies are still relying on traditional Integrated Service Digital Network (ISDN) technology for their business communications, most of which are now becoming obsolete in a business environment where terms of interaction are dictated by increasingly demanding customers.

With the phrase ‘always on’ an expectation rather than a bonus, moving to a modern system is becoming a necessary step for businesses that are serious about how they communicate.

In this guide, we explore how the telecommunications landscape is changing, why businesses are moving and what the map to change looks like. We also see how one business revolutionised their communications by moving from a traditional ISDN-based solution to Session Initiated Protocol (SIP) trunking.
