CallsAround

CallsAround is a 24/7 AI answering service with emergency dispatch for home-service businesses (restoration, HVAC, plumbing, electrical, cleaning). It answers every call with a natural-sounding, configurable AI receptionist, qualifies leads, answers FAQs, and books appointments against your live Google Calendar. When a call is a real emergency, CallsAround doesn't take a message - it dispatches. It rings your on-call chain in order, detects answering machines (voicemail never counts as an answer), sends SMS alerts at every escalation hop, and warm-transfers with context so your tech knows who's calling and why before they pick up. Carrier-level dead-man failover tests the line every few minutes and routes around upstream outages, so callers never reach dead air. Every call is on the record: recordings, transcripts, and a journaled escalation trail. Setup is instant and self-serve - live the same afternoon, no demo call, no onboarding project - with flat month-to-month pricing and no contracts.
