I have a very strange situation which nobody is able to figure out. Issue: When calling my home phone number, a short ring emits and the phone stops ringing. No caller id shows. If the person picks up the phone on the first ring, the call connects. Otherwise, there is no second ring. Here are the facts: 1) I get a dial tone inside the house from all jacks 2) I've tested all jacks with a phone tester and they all test positive 3) The outside phone line rings normally 4) The problem occurs haphazerdly -- The most recent time, there has been a heavy rainstorm. 5) I've tried disconnect each phone one at a time, and then all phones -- the problem still occurrs. Any ideas would be greatly appreciated. Thanks!
