Good point, the ones I am most concerned with (alarm lines) have appearance buttons but that did not help at all with the last Verizon failure.

They do test the lines that have appearance buttons every day but only by pressing the button and hearing dial tone. The last failure had a line that had dial tone and could make calls but was busy when called from outside.

Going to have them call the lines now and also busy out the main number to test the Verizon hunt. Had they been doing that they would have known they had a dead line before I found it yesterday. I only found it because I was doing some re-cableing and tested the old for proper operation before I tore it apart to do the new.

Not the first tome before work tests have saved me from the "it worked before you fixed it" sindrome
