Explanation

Cisco Expressway-C (deployed inside the corporate network) paired with Expressway-E (deployed in the DMZ or outside the firewall) provides the Mobile and Remote Access (MRA) solution. MRA allows remote employees to use the native Cisco IP phone client (Jabber or hardware phones) over the internet without requiring a VPN client. From the end user's perspective, the experience is transparent-no manual VPN setup is needed. CUBE handles SIP trunking to service providers, not remote user access. Expressway's traversal and proxy capabilities make it the correct answer.
