“OpSec is an extremely dynamic organisation that has to make a lot of IT choices at short notice, so I have to be ready for anything. With V12, and the professional support of Charles and his team, I know that I can deliver what my company needs, when it needs it.”

Andrew McGuigan, EMEA/APAC IT Manager – OpSec Security

“It was extremely easy. We basically supplied our company details and were able to offer phone services, leased lines or other connectivity to our customers straight away. It was completely seamless to set up.” 

Chris Taylor Reed, Managing Director - Auckland Micro

“The thing I like most about V12 is that a person answers the telephone, and that’s the key thing for me: I call V12 and I can talk to the managing director or another member of the team and then things happen quickly. They’re very efficient, easy to talk to, cost effective, and easy to get hold of.”

Miles Russell, Practice Manager - The George Veterinary Group

“The solution I got was very quick and effective and I believe so far from my experience with communications companies and telephone companies that with that we’ve managed to get the best possible on the market now”.

Rachid Ghalaine, Operations Manager - Brixton Village
