Can anyone explain how I can make a telephone ring without being connected to the telephone lin. This is for a play.
Thanks

It takes a relatively high AC voltage (~100V) on the telephone line to make it ring. This can be dangerous without special precautions.
Consider playing the sound of a phone ringing through the same mechanism you are using for the other sound effects.
You can rent/buy boxes that will make phones ring (made just for theatrical purposes like yours). Or you may be able to borrow one from a theatre company in your area?
You didn't state your budget (if any) and lead-time until you need it. (And availability of electronics expertiese for possible construction.)
