• D

Explanation

Expressway Mobile and Remote Access (MRA) supports a defined subset of Jabber features. (C) UDS (User Data Services) directory search is supported via MRA because UDS queries are proxied through the Expressway traversal path. (E) Visual voicemail is supported via MRA through the Cisco Unity Connection REST API traversed over the MRA path. Deskphone control mode (CTI) is NOT supported via MRA because CTI requires a direct JTAPI/CTI connection to CUCM that cannot be tunneled through Expressway. Silent monitoring and call recording are NOT supported via MRA due to the media and signaling architecture requirements. LDAP directory search without UDS proxy is NOT supported via MRA because LDAP requires direct TCP/UDP access to the LDAP server, which is not available over the MRA tunnel.
