" " # " 1. The telephone line must be a dedicated, analog line. Never “Assume” it is. Connect a telephone to the phone jack and call 1-847-465-0001(Chicago office) or 1-519-758- 8111(Canada) to make sure there is no “9” or code required to dial out. We can accommodate a “9”before the number, but we cannot accommodate a dial out code.
