On "7th Heaven" of 10/17/05, a traditional black 500 set rotary phone was used to help set the scene of a dumpy situation. The phone was next to a bottle of liquor. A person was sleeping and when the phone rang he pulled the pillow over his head to ignore it.
The ringing sound for the phone was like a Trimline, which has a single gong ringer (a bit more pleasant sounding than the dual gong ringer of a regular phone set.)
For many years, on TV the ringer sound for a telephone often did not match the telephone set shown. In earlier years a 300 set or separate bell box ringer would be used for a 500 set. In later years, a modern phone with an electronic ringer would still sound like a mechanical bell and vice versa.
