This section describes how to properly configure the call forwarding service to prevent unnecessary call forwarding and save enterprise costs.
Context
Figure 1 shows a call forwarding scenario.
Figure 1 Call forwarding scenario
In this scenario, if an enterprise user has the toll call rights and this user's call forwarding service is changed to forward calls unconditionally to non-enterprise user B, all calls from non-enterprise user A to the enterprise user will be forwarded to non-enterprise user B.

ϒ⁄Limit the call rights of enterprise users. For example, in this scenario, if the enterprise user does not have the toll call rights, user A's call cannot be forwarded to user B.
ϒ⁄Properly configure the call forwarding services according to specific user requirements.
