How Does VoIP Work in London?

From London, VoIP takes your voice from the handset and turns it into digital code so it can be translated and outputted to another handset basically anywhere in the world - from London to Cape Town, Africa or London to the Philippines or anywhere else.

The digital code is called "packets" - not like packets of jellytots - but packets of voice data. Yes, it's clever how it works, and can you imagine when it was invented - the thrills they had at the time, you can imagine.

And it's very fast...

London is the main communication hub with the world's largest call centres based here in London. The BT tower is where it's all at, as most companies who provide VoIP telephony use the BT tower in London and the BT company.

So does that mean you go direct to BT VoIP?

No. There are other options other than BT - not to say BT is a bad provider of VoIP - not at all. We're saying that in today's world in 2025, others can offer your London office more and the pricing may be better also. Conglomerates usually have higher prices as a rule because they always have higher business costs like TV advertising and so forth.
