Which two are functions of a local gateway in Webex Calling? (Choose two.)
The correct answer is A. providing PSTN access to users in the local location E. connecting Webex Calling with an on-premises Cisco UCM. Local gateways in Webex Calling primarily provide local PSTN access for users in a specific location and enable hybrid connectivity with an on-premises Cisco UCM. These functions bridge cloud calling with existing local and on-premises infrastructure.

Why each option
Local gateways in Webex Calling primarily provide local PSTN access for users in a specific location and enable hybrid connectivity with an on-premises Cisco UCM. These functions bridge cloud calling with existing local and on-premises infrastructure.
A local gateway in Webex Calling provides direct access to the local Public Switched Telephone Network (PSTN) for users in that specific geographic location, allowing them to make and receive calls using existing local telephony infrastructure like PRI or local SIP trunks.
Webex Calling endpoints typically connect and register directly to the Webex Calling cloud over the internet, not through a local gateway for their primary connectivity.
The Cisco Calling Plan provides PSTN connectivity directly from the Webex Calling cloud and does not require a local gateway for its operation.
Cloud connected PSTN services, like the Cisco Calling Plan, utilize the Webex Calling cloud infrastructure for PSTN access and do not typically route through a customer's local gateway.
Local gateways facilitate hybrid deployments by connecting the Webex Calling cloud service with an existing on-premises Cisco Unified Communications Manager (UCM), enabling call routing and feature interoperability between cloud-registered and on-premises users.
