Workflow + decisioning builder

Orchestrate every branch, takeover, and transfer from a single spec

Define how Callee speaks, what data it references, and where it hands off to humans. Every branch is source-controlled and tied to your compliance checklist.

Operators can see the same spec inside the console, jump into any room, mute the AI, or let Callee finish the call while transcripts, summaries, and DICE segments sync back to your CRM in realtime.

Revenue recovery autopilot

Spin up thousands of concurrent repayment calls, thread in humans when sentiment dips, and post outcomes back to your ledger.

Inbound router + IVR

Drag workflow nodes or deploy programmatically. DTMF, speech, and CRM checks determine if the AI continues or transfers.

Operator console hooks

Supervisors watch transcripts live, drop in, or kick the AI. Console events let you automate everything.

Segmentation + CRM sync

Callee labels every call with DICE, WAOE, WACE, WAOR, or DICR and syncs the segment so your team knows who they are calling.
