# Microsoft (Open Verifiable Calling)

Microsoft's own account, on its Inside Track blog of 18 June 2026, of using Open Verifiable Calling for outbound calls with Provenant as its signing-service partner. The post does not name KERI or ACDC; Provenant's page says Microsoft has run the reference implementation in production since April 2026. Source read 21 October 2026: the blog post.

Labels: reading level Practitioner; evidence official (a statute, a regulator's document, or a standards body's own page).
