For some years now ISDN has been a stable and reliable platform for connecting corporate phone systems to the public telephone network. BT’s solid network provides nationwide coverage and multiple trunk capabilities to small and large business alike with rock solid reliability and performance.
When launched over a decade ago ISDN also promised fast data and video transmission although in reality, it never really delivered on this promise.
While ISDN data connections were much faster than the alternative analogue modem, it very quickly became overtaken by broadband technologies and was unsuitable for anything but very small businesses.
It can be forgiven for that though as the demand for data quickly surpassed most predictions as the world woke up to the potential of the new fangled ‘internet’ and the speed limitation of ISDN was always going to struggle with bandwidth hungry applications.
In those days there was no such thing as Skype and video conferencing was often reliant on bonding lots of ISDN channels together into a dedicated system tucked into a trolley in a meeting room. In many cases the end result was pretty poor and was very expensive to use.
For voice though, the stable, consistent service was just the ticket for clear, reliable communications from PBX to public phone network so when alternative technologies such as SIP came along, there was an understandable reluctance to ‘jump ship’.
However, as with all technologies, it has a finite lifespan. It will become a thing of the past and it will be consigned to the history books just as soon as the alternatives prove they can take over the mantle. And that time is here.
To be fair, IP based services such as SIP have been up to the task for a while now but it has taken time to generate the required confidence from the end users. Poor SIP implementation can also be blamed for putting some people off using SIP as inexperienced or unscrupulous telecoms suppliers try to deliver SIP using low grade connectivity without the appropriate service levels, culminating in poor call quality or unreliable connections.
As with any technology, poor implementation will only deliver poor results, but correctly implemented SIP can offer a wide range of benefits when compared to ISDN including excellent Disaster Recovery options & number migration capabilities with exceptional costs savings (we offer ours for free, and that’s as cheap as it gets!).
So ISDN has served us well and it will be around for a few years to come as there is still a lot of connected ISDN equipment out there but the take-up for SIP is huge and growing rapidly so it seems it truly is the beginning of the end for ISDN. The question is what’s really driving this? Is it the need for better, more scalable, more integrated communications, a need to protect the business during a disaster or cold hard cash savings?
Personally, I’d happily take all three benefits but what would tempt you away from ISDN?
