Description
I have a bit of phone anxiety, and have a ton of dread around making phone calls to restaurants, banks, doctors, and so on and on.I thought: AI could do this with a web form turned into a prompt.Stack started out simple -> using 11labs for voice + claude + twillio, but it actually got rather complex (even though I tried vibe coding most).First off, finding the phone numbers quickly is hard. This is done by scraping the web with some basic duckduckgo search and structure with openai calls.Second, collecting the right information. I’m still struggling a bit with this but the architecture is that: A) user puts in call objective and business name B) if keywords are detected spin up one of the default form categories C) if not, get structured json from gpt-4o-mini and turn into react formThe cost of making a single call spun out of control, but luckily sonnet can handle a lot of the calls and I’m ok paying for twillio.Ended up taking months to build my week-long project because of course.It’s still WIP so feel free to email me: [email protected] with any ideas or issues u ran into. \

Could you build this?
Partial While basic telephony voice agents are straightforward to wire up, building an agent that reliably navigates interactive phone menus (IVR/DTMF), handles long hold times, and deals with complex customer service representatives requires complex state-machine orchestration.
What it would actually take: The architecture relies on Twilio for telephony, Deepgram/ElevenLabs for streaming audio, and an LLM orchestration layer via WebSockets. The challenging parts include robust dual-tone multi-frequency (DTMF) detection/generation to navigate automated phone trees, silence/hold-music detection, and low-latency interruption handling when a live human picks up. Specialized voice pipeline engineering is needed to prevent audio desync and handle edge cases during hour-long support calls.

Same idea, different domain
Nobody's really built a agent / copilot tool for Agriculture yet.
