HOTSPOT
You need to configure the Exchange Server UM dial plan for the planned integration of UM and Lync Server.
How should you configure the UM dial plan? (To answer, select the appropriate dial plan type and VoIP security
mode in the answer area.)
Hot Area:
Answer: 
Explanation:
* Scenario: Integrate Unified Messaging (UM) services with the Lync Server 2013 infrastructure.* If you want to integrate Exchange Unified Messaging (UM) with Lync Server 2013, you must perform the
following tasks:
/ On the Exchange UM server, create a SIP dial plan based on your organization’s specific deployment
requirements.
/ To encrypt Enterprise Voice traffic, configure the security settings on the Exchange UM SIP dial plan as SIP
Secured or Secured.
Etc.
Note:
* There are three formats or URI types that can be configured on UM dial plans:
/ Telephone Extension (TeleExtn)
/ SIP URI
Session Initiation Protocol (SIP) is a standard protocol for initiating interactive user sessions that involve
multimedia elements such as video, voice, chat, and gaming. SIP is a request-to-response based protocol that
answers requests from clients and responses from servers.
/ E.164
* 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.
