Genesys Cloud Voice availability varies by AWS region with specific data sovereignty and service restrictions. In the FedRAMP region, organizations can provision phone numbers and access domestic and international calling services for the United States only, with voice services for other countries unavailable. The European Sovereign Region (ESR) provides data sovereignty commitments for voice services exclusively within designated ESR boundaries; ten EU countries including Austria, Belgium, Denmark, Ireland, Portugal, Spain, and Sweden receive full coverage for DID numbers, toll-free numbers, and domestic calling under ESR commitments. However, phone numbers and calls to destinations outside ESR coverage areas utilize non-EU carriers and third-party integrations, resulting in voice, signaling, media, and metadata processing outside the EU without ESR data sovereignty protection. Numerous countries across APAC, North America, LATAM, and EMEA regions—including Australia, Canada, France, Japan, Mexico, and the United Kingdom—have services available but are not covered under ESR data sovereignty commitments. The European Sovereign Region feature remains in Limited Availability; organizations should contact their Genesys account team for current availability details.
