Abstract
Routing a call includes receiving a request to initiate a call session for a call from a caller endpoint to a callee endpoint, where the caller endpoint belongs to an internal network. Whether the call is internal or external is determined. A routing mode is selected in accordance with the determination, and the call is routed according to the selected routing mode.
