Function guide
Calls — the same marketplace, in real time. In development.
Voce is the call transport — the synchronous sibling of Nota. A live inbound call is a lead that can’t wait: it runs the same auction (Galleria) and settles on the same ledger (Maestro), but the transport is a phone call instead of a data post, and delivery is a live transfer instead of an HTTP POST.
| Leads (Nota, today) | Calls (Voce, planned) |
|---|---|
| Post a JSON lead | A live inbound call / SIP leg |
| Ping = reserve, Post = deliver | Ping = reserve while the caller holds, Post = connect the transfer |
| Deliver via HTTP POST | Deliver via warm transfer / SIP refer to the winning buyer |
| Settle on delivery (CPL) | Settle on connected + qualified duration (pay-per-call) |
Voce leans on Libretto for a call certificate: it captures the caller’s ANI, the STIR/SHAKEN attestation, and the spoken-consent evidence, and seals them the same way a web form is sealed. Planned call-specific integrity features include blind-transfer verification (proving the supplier’s leg released on transfer) and a tone-based liveness validator.
Because Voce reuses the auction, ledger, returns, and CRM already built for leads, the marketplace economics (auction, taper/flat fees, three-party settle, returns) carry over unchanged — only the transport differs.
Until Voce ships, calls are handled through the existing call-cert capture — see Call setup recipes and Libretto.
