Hackathon honorable mention: RingBack by Ludovic H.

A slot opens up at a physio or a hairdresser. CALL-E calls the waiting list one person at a time, and the first yes takes it. Nobody else gets called.

"They don't need a dashboard. They need someone to pick up the phone."

[CALL-E @heycalle]

status tells you how the call ended.

task_completed tells you whether the job got done.

Your agent needs both before it says "done".

CALL-E Hackathon honorable mention: Care Call AI by Alex Raixon.

For charities supporting people at home with severe illness or disability. A coordinator approves check-in calls, CALL-E asks what everyday help someone needs today, and confirmed needs become same-day requests.

What's one phone call you've been putting off this week?

Real question. We read every reply.

[CALL-E @heycalle]

Before you drive across town for the last one in stock, ask your AI assistant to call ahead.

CALL-E checks with the store and tells you what they said.

CALL-E Hackathon winner, Most Innovative Use Case: Conversation-Clarify by K S.

You ask "Monday or Tuesday?" They reply "Yeah, I'll be there."

The Gmail extension spots replies like that. After you approve, CALL-E makes one short call to ask, and drafts the reply for you to send.

The retention line's job is to keep you paying.

Ask your AI assistant to call your cable company about a lower rate. CALL-E plans the call, checks it with you, then dials. You get back what they offered.

[CALL-E @heycalle]

Is the prescription ready, or is it "another 20 minutes"?

Ask your AI assistant. CALL-E calls the pharmacy and tells you what they said.

[CALL-E @heycalle]

plan_call drafts the call. It never dials.

run_call places it, with the plan_id and confirm_token from the plan.

Show your user the plan in between.

CALL-E Hackathon winner, Most Practical Use Case: Local Atlas by Omar Miri!

A question no listing answers becomes one CALL-E call to the business. The answer is saved, dated and quoted, so the next visitor doesn't have to call.

"One phone call becomes everyone's answer."

[CALL-E @heycalle]

Press 1 for billing. Press 2 for… you know how this goes.

CALL-E listens to the phone menu, presses the keys and waits on hold. You get back what they said.

[CALL-E @heycalle]

Some phone lines are built so you give up. Cancelling a subscription is the classic.

Ask your AI assistant to make the call. CALL-E plans it, you confirm, it dials, and you get back what they said.

CALL-E webhooks wait for the useful part.
