Telecoms for Cambridge businesses
Cambridge's science parks and biotech firms often grow quickly from a handful of people to dozens. A cloud phone system lets you add users in minutes rather than waiting for new lines.
We set up and support everything remotely, and our services are delivered across England. Where an engineer visit is needed for broadband, leased lines or cabling, we arrange it through national partners.

Can I get a 01223 number if my office is not in Cambridge?
Yes. A virtual 01223 number can ring any phone in the UK, which is useful if you serve customers in Cambridge from another base or work from home. The number should be used for genuine business in or with the Cambridge area.
