Note:
After you create a Unified Messaging (UM) dial plan, you can view and configure a variety of settings. For example, you can configure the level of Voice over IP (VoIP) security, the audio codec, and dialing restrictions. The settings that you configure on the UM dial plan affect all users who are linked with the dial plan through a UM mailbox policy.

Explanation:

* Scenario: After a change to a certificate, users report that email messages sent to
Fabrikam are not delivered.
* ProtocolLog
Protocol logging records the SMTP conversations that occur between messaging servers as part of message delivery. These SMTP conversations occur on Send connectors and
Receive connectors that exist in the Front End Transport service on Client Access servers, the Transport service on Mailbox servers, and the Mailbox Transport service on Mailbox servers. You can use protocol logging to diagnose mail flow problems.

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.
