Whose voice is it on the phone recording “If you’d like to make a call, please hang up and try again. If you need help, hang up and then dial your operator.”?
Joey.
Lily Tomlin?
James Earl Jones
Joan Kenley, aka “The Telephone Lady”, as featured on The Simpsons.
Sorry it took so long to come up with the answer. 
The OP you dialed has been disconnected or is no longer in service.
But for posterity it was very probably Jane Barbe or her successor as the voice of Ma Bell, Pat Fleet.
