Digital Answering Machines

I’ve been having trouble with my landline phone , & I have dial up
internet, when discussing it with a friend I was told my computer tower is going out , but I don’t have any problems getting on line
or browsing the web.,can someone help, the only problem I have
is with my lannd line phone when I try to call out , when I’m off line
sounds like a fax , then just disconnects.the phone company
thought it was my digital answer machine so I turned it off, then
they suggested I get another phone , did but it still acts up .
not all the time just randomly, any suggestions?

the home phone/answering machine i have now is annoying,,i think its an a t &t…has a digital answer machine,,a phone on the base unit and 2 cordless handsets…the range is poor even tough my house is very small, one level,less than 1000 square feet….also you cant use both handsets at the same time,in case two people in the house want to talk to the same caller….if thats the case,,one of us has to be the corded phone at the base set,,but range is the bigger issue…what is a good brand with longer range and more flexibilty in how phones are used??,,,also more storage space on the answering machine would be nice too……dan
