E. 通話応答ルール
Correct Answer: A,B
Explanation:
* Scenario: Voice mail traffic between the telephone system and the Exchange Server
environment must be encrypted.
A: Use the EAC to configure Protected Voice Mail from authenticated callers
* In the EAC, navigate to Unified Messaging > UM dial plans. In the list view, select the UM
dial plan you want to modify, and then click Edit.
* On the UM Dial Plan page, under UM Mailbox Policies, select the UM mailbox policy you
want to manage, and then click Edit.
* On the UM Mailbox Policy page > Protected voice mail, under Protect voice message from
authenticated callers, select one of the following options:
* Click Save.
B:
* In on-premises and hybrid deployments, you can configure a Client Access and Mailbox
server to use mutual Transport Layer Security (mutual TLS) to encrypt the SIP and RTP
traffic sent and received from other devices and servers. When you configure the dial plan to
use SIP secured mode, only the SIP signaling traffic will be encrypted, and the RTP media
channels will still use TCP, which isn't encrypted. However, when you configure the dial plan
to use Secured mode, both the SIP signaling traffic and the RTP media channels are
encrypted. An encrypted signaling media channel that uses Secure Realtime Transport
Protocol (SRTP) also uses mutual TLS to encrypt the VoIP data.
* When you're deploying Transport Layer Security (TLS) with UM, the certificates that are
used on the Client Access server and the Mailbox server both must contain the local
computer's fully qualified domain name (FQDN) in the certificate's Subject Name. To work
around this issue, use a public certificate and import the certificate on all Client Access and
Mailbox servers, any VoIP gateways, IP PBXs, and all the Lync servers.
