Explanation

For Mobile and Remote Access (MRA) to function, the Expressway-C must be configured with the Cisco Unified Communications Manager (CUCM) publisher address. This is required because Expressway-C queries CUCM (via the publisher) during the MRA provisioning process to discover services, authenticate users, and retrieve endpoint configuration via the UDS (User Data Services) API. Without this address, Expressway-C cannot communicate with CUCM to enable MRA endpoints to register and receive services. IPS (choice A) and SSO/SAML (choices B and D) are optional enhancements - SSO/SAML can be layered on top of MRA for single sign-on, but neither is a base requirement to get MRA operational.
