What is a capability of configuring the Incoming call permissions in a Cisco Webex dial plan?

"Chargeable directory assistance calls" are outbound calls and are typically controlled by dial plan rules and class of service for outgoing calls, not incoming call permissions.

"Disable operator assistance calls" is typically an outbound call control or a feature related to internal operator services, not a direct capability of incoming call permissions in the context of general dial plans.

Cisco Webex dial plan configurations, specifically Incoming Call Permissions, can be used to control whether users are allowed to receive collect calls. This feature provides flexibility in managing call types and associated billing or operational considerations, ensuring that only authorized or desired call types are permitted inbound.

"To stop users from making collect calls" refers to outgoing calls, not incoming calls, and would be controlled by outbound dial plan rules or class of service restrictions.
