Zone Block Direction

The blocking function restricts sending out SIP requests outside an existing dialog from your network to an opposite network, but does not restrict sending in-dialog requests to the opposite network. Incoming SIP requests are not restricted, and test calls are sent to the opposite network even when the blocking state is OUTGOING.

Command Syntax

Use this command to block incoming /outgoing calls based on the selected direction.
