Calldone answers inbound calls around the clock, qualifies the caller, books appointments into your calendar, and routes or escalates without a human touching the interaction. The agent handles multi-step tasks autonomously: collecting patient intake details, scoring a sales lead, or confirming a restaurant reservation in a single call. The pay-per-minute model means low-volume months do not carry a flat seat cost. The ceiling appears when call flows need complex conditional branching — the vendor does not surface a visual workflow editor, so non-standard routing logic requires direct configuration support rather than self-serve adjustment.
