Voice Call One-Way Audio from Brazil to a Subset of Twilio Numbers

On October 31, 2026, from 5AM to 8AM PT, customers may have experienced an issue with some inbound calls to Twilio Brazil numbers having no audio, and some calls also dropping. The impact was linked to a carrier fiber cut and a fallback route that could not handle the traffic load. The issue has been resolved and Voice is operating normally. (Affected: Voice, Latin America)
