determine if the problem is with your telephone or the telephone
company lines. BEFORE CALLING THE TELEPHONE COMPANY, be
aware that they may charge you for a service call if the problem
is caused by your telephone.

Unplug your telephone from the wall jack. Plug a substitute
telephone that is known to work properly into the same wall

telephone repaired before reconnecting it to the wall jack.
