[Grammar] no sooner had I

[Oceanlike]

I don't know if I need to the word 'again' in writing the following sentence:

No sooner had I put the telephone now than it rang again.

I want to write differently from "The telephone rang again immediately after I had put it down.". Just trying.

Is 'again' needed? I think it is not needed but I am not sure.

Thank you. :-D

Without 'again', readers do not know the phone rang before you picked it up.
The phone did not need to ring before you picked it up and made a call.

It should be 'down' rather than 'now', a typo.

It depends on whether it important to know that this was not the first time the phone had rung. Theoretically, you could have made the phone call so we have lost some information, but I can live without it.
