I have a customer and moved phones around when I did a page on one phone it Squealed after that seem when they paged it would just cut off and I could hear clicking with static in the handset when paging it still rings on incoming calls thru horns. Could the squeal of cause the page port to go out power down system and seem to work one time. Have a valcom 2001a as paging amp. Powered it down and didn't make a difference. Anyone have this problem before or could it just of been a fluke? mad :bang:
