Solution to the random dialout issue depends on
whether the vulnerable phone actually makes and breaks
the line. 

See if you can dial someone and have them listen to
the call while you're transmitting. If it hangs up,
there's probably some inductive kick that can tickle
the innards of the phone, causing contact bounce. If
the bounce takes place rapidly enough, it can "pulse"
dial a phone line. 

Some office I worked at used to lock the dial on the
rotary phone, but if you clicked the receiver hangup
bar quickly enough, you could dial your number just

If the call remains completed, then just dialup your
computer service or something else, and keep the phone
line busy so the clicks cannot obtain a dialtone and
cause mayhem.
