Is ISDN dead? What is SIP?
5th January 2017 Voice, Jim Marshall
In his first video blog, Jim Marshall-Andrew – Nomis Connections’ Sales & Marketing Director – looks at the truth behind claims that ISDN is dead, and gives a top-level overview of SIP Trunking.
At the end of last year, we discovered that BT intend to remove the grand old telephone box from our streets. Why? The technology is old, and very few people use them.
This seems to be a bit of a trend at the moment, as it’s also one of the most frequent questions I get asked about ISDN.
Is ISDN dead?
Well, no – not yet. It is true that BT have announced the phase out of the service, which like the mighty phone box is being replaced by newer technology, but this won’t be happening until 2025. There’s no unnecessary rush from our perspective, nor should there really be from yours.
So what’s replacing ISDN? The answer is SIP Trunks.
What is SIP?
While there’s no immediate need to rush out and cancel your ISDN right away for fear of being disconnected next week, it is still worth looking at SIP as its benefits go beyond a simple change of infrastructure – and it’s likely what you’ll move to.
Really, the easiest way to illustrate what SIP is, how it differs to ISDN, and the benefits it offers, is to sketch it out. This is exactly what I’ve done in the first of a series of video blogs designed to demystify the techy world of telecoms.

While we do have time, the increased efficiency, flexibility and cost savings that SIP Trunks bring may mean you want to look at moving before the 2025 deadline. If that’s the case, you’re in the right place.
