This signal won't interfere with most phones, but certain types have a ring circuit that is oversensitive. Normally, it takes approximately 90 VAC to trigger a ring, but some phones will trigger on less, hence the problem. The solution: try changing the phone.

that is probley why its happening that makes sence, thx alot beeble you solved the case to the haunted phone mysterey
