Your business will now be aware by now that as the 2025 PSTN (Public Service Telephone Network) and ISDN (Integrated Services Digital Network) switch off draws closer, you’ll need to be making choices as to your future requirements. Often terminology can be confusing, i.e. VoIP (Voice over Internet Protocol) & SIP! (Session initiated Protocol)

What’s is the difference between VoIP and SIP?

Often, we talk about VoIP and SIP as though they’re two totally different things but technically, they have a lot in common.

VoIP is the provision of hosted seats, the VoIP phone system being on the Internet whereas SIP is the provision of SIP Trunking, as a direct replacement for ISDN. Hosted Seats use SIP signaling to initiate the session to send calls to an Internet Protocol (IP) provider. Essentially, they do the same thing.

That’s the main difference between the products: If  you want to keep the existing office PABX, as an interim step to VoIP, keeping your existing phone system you’ll need to use SIP. If you want to replace your PABX, you’ll need VoIP it’s as simple as that!
