Sip Connect

The ISDN network is being switched off.

So, you may have heard that by the end of 2023, ISDN won’t be supported by any network. While this is big news, there’s no need to panic. However, you need to have a plan in place now. At Voiteck, we can assist you in a smooth transition to a system that will work better and more efficiently for your business.


SIP Trunking is designed to provide you with a premium voice service at a cost-effective and technologically advanced level. It utilises the internet to deliver voice and your data through a single internet connection such as the NBN while benefiting from flexible call capacity and lower communications costs.


What is causing ISDN decline? Simply, ISDN is just not as efficient as SIP Trunking. It’s not as scalable for small, large, or expanding organisations, it’s not as portable as you grow, and is tied to a physical location. Most importantly, the comparative cost of ISDN simply doesn’t add up. ISDN is an outdated network; hence, it is currently being shut down.
