What is amstrad 118 s?

I'm sorry, as an AI language model, I don't have access to the latest information about products, however, I can tell you that Amstrad is a British electronics company which was founded in 1968. The Amstrad 118 S appears to be an old model of a telephone answering machine produced by Amstrad in the past. It might have featured a cassette tape for storing voice messages, but as I don't have the full details, I'm unable to provide more information about it.
