Microsoft Teams: PSTN calling blocked on Teams phone devices in India when emergency location is not configured

PSTN calling on Teams phone devices in India using Operator Connect is blocked if emergency locations are not configured, per telecom regulations. Admins must set emergency addresses and verify Location-Based Routing to restore calling. This change applies to Teams app version 1449+ and ensures regulatory compliance. What and Why To meet telecommunications regulations in India, Teams now requires an emergency location to be configured for Teams phone devices using PSTN calling with Operator Connect. This location helps verify that devices are operating within India. If a device cannot be validated, PSTN calling will be blocked to comply with regulatory restrictions on call routing.
