Have you tried unplugging all telephone equipment (including - cordless 
phones, answering machines) before connecting with your dialup modem ?

If you have more than one telephone device/socket in your house - have 
you tried using a different socket for the dialup modem ?

Then - when you have a stable connection with your dialup modem, plug in 
the other telephone devices - one at a time and check your connection 
before you again plug in any/each other device. 

It could take quite a bit of time to sort it out - but it could highlight 
a problem with other devices on your line.

If you are in a remote area on a remote line that is affected by moisture 
at connection terminals and junctions boxes, you could be getting side 
effects caused by voltage swings - especially when another subscriber in 
your area receives an incoming ring tone on their line. 

This might cause your modem to hang up.
