Definition
A vCon (virtual conversation) is an open, standardized container for conversation data that packages a conversation's participants, recordings or transcripts, analysis, and attachments into a single portable JSON document, and is being standardized through the IETF.
A vCon is organized into sections for the parties to a conversation, the dialog itself (recordings, text, or references to them), analysis such as transcripts, summaries, or sentiment, and attachments such as related documents. Because the format is common, a conversation captured by one system can be read, analyzed, and audited by another. vCons can be digitally signed and encrypted, so a recipient can check that a record has not been altered.
Companion drafts extend the core format, including work on recording consent and the lawful basis of a conversation inside the vCon. A signed vCon can also be anchored to a transparency ledger built on the IETF's SCITT (Supply Chain Integrity, Transparency and Trust) architecture, to prove that a record existed in a given form at a given time. The vCon Foundation, founded by Jeff Pulver, promotes adoption and presents the vCon Summit.
For regulated outreach, the appeal is evidence. A consent record or disclosure written into the conversation record itself, in a format any compliant system can read and any auditor can verify, is stronger proof than a one-off log inside a single vendor's database, and it helps a program show after the fact that consent existed at call time.
How Consig handles it
Consig's session at the 2026 vCon Summit in Atlanta (October 13, 2026), led by Head of Product Andreas Volmer, argues for signed, ledger-anchored vCons as the audit backbone of an outbound AI voice call, and for treating consent as shared infrastructure rather than something each vendor reinvents.
