I have just replaced our phones, with a set which filters out nuisance

get through.

My new concern is that we sometimes get automated calls from the
electric, gas, flood and water utilities, when they have an issue and
we obviously want these calls to get through - so I need to find out
the numbers they use to ring us from, so I can include them in the list
of accepted numbers.

Has anyone found such a list, or even a proper name for this type of
prerecorded warning phone call?


The obvious answer is to ask the utilities concerned.

Do they really call so frequently that missing the call would be a
concern?

Its not the frequency that matters, its the nature of the calls.
Some can be real emergencies that you dont want to miss
and by definition those are not likely to be frequent at all.

Even just a warning that power will be off for hours as they do
maintenance on the system is useful to get even if uncommon.

Incidentally our Truecall unit blocked 8 nuisance
calls on Wednesday. Best thing we've ever bought.
