I recently picked a lovely cream 50’s style telephone which i’ve connected to my phone socket and it works – hurray. However, I can’t use it to check my answering machine as it has a dial, not touch tone. I once had a small dtmf tone generator which came with an answering machine, but can’t find it. Googling finds a million bits of software and apps, but I’m looking for a piece of hardware to do the job.
Anyone know of one?
