SOURCE: Mitel SX-50 phone console keeps ringing for no reason.
first make sure it is not a line problem by disconnecting the phone line when you get the rings, then make sure it is getting proper power to the unit. if it does not have electric plug look for batt in unit and replace. If unit is dirty, gummed up try blowing out with air, before giving up on the unit. good luck
