Has anyone found an outlet to purchase PARTS for Aastra (or Polycom for that matter) phones? My current example is that I need standup bases for two Aaastra 480i phones. My provider cant get them, ebay doesn't have them, Aastra is no help. Anyone? I really do not want to have to pay top dollar and bid on phones on ebay I wont use just to get a plastic base that shouldn't even cost $10. (though I know it will be more like $25)
