Do you have a cordless phone? Check that it’s fully charged
Check all your phones to make sure they are on the hook and that all the phone cords are plugged in and secure
Is the problem with only one phone? Then it’s likely to be a fault with the phone and you will need to contact us

My telephone line dials out but does not ring inbound

Check your ringer - make sure it's switched on and test it by calling your number from a mobile.

Are you using a cordless phone?
Make sure it's fully charged, a low battery can cause more problems than you'd think!
Do you still get the problem if you connect a standard corded phone? If not you'll need to speak to the supplier of your cordless phone
Check your microfilters and broadband setup
All equipment connected to your line needs to pass through a microfilter

I used to have Caller ID on my line but it has disappeared

This could be an exchange fault, please contact us and we will raise a fault.

Is the number coming up withheld when you’re making outbound calls? If yes, then contact your network provider who can remove the feature "withhold number when calling". If no, then contact your network provider who can look into this for you.

My line is crackling and is hard to hear

Check that all the telephones in your premises are properly connected, even if you're only having problems with one of them.

Are any of your phones off the hook?
Look at the telephone cables and any power cables - are they securely plugged in?
Check micro-filters are installed where required
For cordless telephones, please make sure the battery is charged

If none of the above steps work, please call your network provider.
