Why each option
Mobile and Remote Access (MRA) through Cisco Expressway supports Single Sign-On (SSO) for endpoints, allowing users to authenticate once and gain access to multiple collaboration services.
SSO (Single Sign-On) is a key feature supported by MRA, enabling users to authenticate their collaboration endpoints and applications with a single set of credentials, typically via an identity provider.
H.323 registration proxy is not a core feature supported by MRA for endpoint registration; MRA primarily uses SIP for endpoint registration to CUCM.
MGCP (Media Gateway Control Protocol) gateways do not register through MRA; MRA is for endpoints like IP phones and soft clients, while MGCP is for gateway control.
SRST (Survivable Remote Site Telephony) provides call processing redundancy for IP phones at a remote site when the WAN link to CUCM fails, which is a local site survivability feature and not provided via MRA.
