I ever so carefully updated the phone with a new RJ-30 jack (the original was bare wires), so that in a custom built base that the phone sits on is an Nvidia Jetson running an LLM and trained on Charlie Brown's voice and a voice recognition model.
Dialing 1 will answer questions about Snoopy and Peanuts history and Charles Schultz in Charlie Brown's voice. You can just talk to it. Dial 2 and a very nice lady with a British accent will read you a bedtime story, interactively, like a choose your own adventure of sorts, from a large database of stories. Dial 3 and Lucy will pick up, announce that the therapist is in, and talk with you about what's troubling you, again, voice recognition and an LLM. Dial 4 and you get Woodstock. Any other number gets you an "adult" from the Peanuts cartoon that is impossible to understand, again, voice recognition to understand what you're asking, but the response is unintelligible.
