We will aim to fix your phone line fault by the end of the next working day.

You can report faults 24/7/365 online or by phone:

But you may not need to contact us at all: our comprehensive set of FAQs and help articles on our website, plus help from other customers on our support forums,  should answer most questions.

Protection against both cable and local exchange failure.

• We provide your ISDN over 2 different routes
  
• Different cables, ducts (where available), and building entry points
  
• Routing from 2 exchanges to your premises 

If your site has been compromised, we’ll divert all your incoming calls to a single pre-arranged number.

ISDN30e channels duplicated at a standby site that we activate when you can’t use your main site.

We connect your site to 2 exchanges with the same number range across both exchanges.  

So if one exchange fails, you’ll still get your incoming calls delivered from the second exchange. 

If you’d like to add direct dial in numbers to your lines you can upgrade from £4.81 per channel per month  (ex VAT)
.
