[RFI] Help: Telephone Ringer Blown Out

[Eric Rosenberg]

We seem to have had a phone line hit. 

We have six phones in the house, two wireless (same model), one wired,
and a  fax machine with a wired answering machine/phone plugged into it. 

What I don't understand is how/why the ONLY ringers went out, and ONLY on
the two wireless and wireline phones and *not* the fax machine or phone
attached to it.

Can someone tell me what happened and what I can do so that this won't
happen again. 

Thanks in advance,
