Bigly Sales runs AI outbound and inbound calling as a managed service. Its AI voice agents call new and aged leads, qualify them against your criteria, live-transfer interested prospects to your team, book appointments, and answer inbound calls 24/7, with every disposition, transcript and recording written back to your CRM.

Bigly also handles phone-number procurement, carrier registration, more than 200 whitelisted local-presence lines, spam monitoring and call routing. Before every dial, the system checks consent, suppression and DNC lists, known TCPA litigants, and state and federal calling rules and quiet hours.

Lead sources are ranked side by side by success rate and cost. An hour-by-hour chart shows when leads convert. With the Bigly Sales MCP server, customers can manage campaigns from Claude or ChatGPT: push a list into an active campaign, check minute usage, pull transcripts, or ask which leads want a demo.
