Which deployment model minimizes dependence on internet connectivity for core collaboration functions?

Anon-premises deploymentmodel minimizes dependence on internet connectivity for core collaboration functions. In this model, all critical services, including call control, messaging, and conferencing, are hosted within the organization's local infrastructure. This ensures that internal communication services remain operational even if internet connectivity is lost.​

In contrast, cloud-based deployments (Options A and C) and Hosted Collaboration Solutions (Option D) rely on internet connectivity to access services hosted externally, making them more susceptible to internet outages.​
