Important: dependency on Microsoft Teams
Teams Phone with Calling Plans is a 100% Microsoft solution. This means that during a Teams outage, your organization cannot be reached by phone. For organizations where phone availability is business-critical, Direct Routing via uWebChat Voice offers more resilience: voice routing runs via a separate path and does not depend on Teams availability.
