Why each option
Cisco Expressway with Mobile and Remote Access (MRA) enables existing Jabber clients to securely register to CUCM over the internet without a VPN connection.
Jabber Guest is a product for enabling external browser-based or temporary guest video calls, not for persistent remote employee CUCM registration.
VCS does not support the MRA feature; MRA is exclusively available on the Cisco Expressway platform.
Cisco Expressway-C paired with Expressway-E provides MRA, which uses secure traversal technology (ICE, TURN, STUN) to allow Jabber clients outside the corporate network to authenticate and register to CUCM via encrypted SIP and HTTPS. MRA is the Cisco-recommended solution for remote Jabber access without VPN, supporting full UC features including presence, messaging, and voice/video calls.
VCS does not support MRA; only Expressway supports MRA for remote Jabber registration without VPN.
