Enterprise Zoom global voice is delivered through three models: native Zoom PSTN (available in 45+ countries), Provider Exchange (using selected carriers where native is unavailable), and BYOC (enterprise-managed carrier connectivity). UCT advises on which model — or combination — best serves each market in a multinational deployment.
Multinational deployments often combine different voice models by country. This comparison keeps the regional decision points explicit for architecture and governance planning.
