# GSMA Foundry launches Open Verifiable Calling project, building on proven live deployments to restore trust in global voice communications

A GSMA Foundry news item announcing the Open Verifiable Calling (OVC) project, which attaches cryptographic proof of caller identity, brand rights and intent to voice calls, and explores adapting the Legal Entity Identifier (LEI) governance model run by GLEIF for telecoms. It invites carriers, vendors and regulators to take part. Description drawn from search-result excerpts of GSMA pages, not from the page itself.

Labels: reading level Introductory; evidence vendor-reported (a company's account of its own product or deployment).
