Next generation technology: SIP Trunks vrs Hosted Telephony, which is best for my business?

Created by

More businesses than ever are turning to next generation solutions such as SIP Trunks and hosted telephony. 


We have covered in many of our blogs that ISDN is a dying technology. Indeed, BT intend to switch their ISDN network off entirely in 2025 and the general consensus is the technology will be as good as gone within five years. But this traditional system is still being used by many businesses. 


ISDN is a communications network that relies heavily on physical infrastructure, specifically copper wiring. It came to prominence because it provided the opportunity to transmit voice and data over the same lines. However, because of its reliance on physical infrastructure to manage calls and additional functionality via a PBX (or multiple), this takes up space within business premises and requires resource to administer and maintain. Similarly, it is hard to add and remove new lines to an ISDN network because it requires the physical addition and removal. 


So what’s the alternative? 


There are two future-ready solutions storming the market right now. SIP trunking and hosted telephony. 


SIP Trunks connect a business’s PBX to the provider’s national network via broadband, Ethernet or a private circuit. 


Hosted telephony is a complete business phone system, delivered over the internet and provided by a host and/or telephony company.
