Subject: phones catching fire
From: Don Wegeng 

On last night's news there was an short segment which mentioned that 
many of the inexpensive phones on the market today may present a fire 
hazard.  Aparently AT&T puts a fuse into the phone to protect against
a short between the phone line and the power line which the low cost 
phones lack.  When AT&T recently simulated such a short all of the
units which did not have the fuse caught fire!

My questions:  Does anyone on the list have any more information about
this?  Should I consider adding some sort of protection to the phones 
which I now have in my house?  If so, what is the best solution?  
Finally, if this is indeed a problem then why is the protection placed
in the phone, and not on the phone line itself before it enters the 
house?

Thanks,

Don Wegeng (dw) Wegeng.Henr@Parc-Maxc.ARPA rocks34!dw

Today, while trying to call someone, I noticed something wrong with 
MCI, something I've never encountered before. When I called the local 
access number (617-262-7775), instead of the normal tone, I discovered
I was attached to a trunk line -- rather, instead of the tone, there
were conversations there. When I punched a button, it stopped. In
other words, it was as if the tone had been replaced by other MCI
users conversations.  In fact, as long as I kept hitting a number and
then '#', I could stay on as long as I wanted to.I didn't get full
conversations, too. After while I would be switched to a new call.
These were full calls, too -- ringing and all. Sometimes even the
person dialing his/her code!

Is this common? Can it be fixed? Isn't it an invasion of privacy? I 
listened to two people talking in very intimate terms, at one point!  
Any comments?
