Configure the unassigned number ranges in the unassigned number table and associate them with the appropriate announcement.
– To create a new announcement, you need to perform the following steps:
1. For audio prompts, record the audio file by using your favorite audio recording application.
2. For audio prompts, run the Import-CsAnnouncementFile cmdlet to import the contents of the audio file to File Store.
3. Run the New-CsAnnouncement cmdlet to create and name the announcement. Perform this step to create announcements with an audio prompt, a text-to-speech (TTS) prompt, or no prompt.
4. Assign the new announcement to a number range in the unassigned number table.

Answer:

Explanation:
Note:
– You can enable or disable the Play on Phone feature for users associated with the Unified Messaging (UM) mailbox policy. This option is enabled by default and allows users to play their voice mail messages over a phone. The phone can be any phone, including an office or a mobile phone.
– A Unified Messaging (UM) dial plan is created using an organization-wide scope and contains configuration information related to your telephony network. A UM dial plan establishes a link from the telephone extension number of a Microsoft Exchange Server 2010 recipient in Active Directory to a UM-enabled mailbox.
– Manage Voice Mail Settings for a User
You can view or set the Unified Messaging (UM) and voice mail features and configuration settings for a user that’s been enabled for UM and voice mail. For example, you can do the following:
– You can create a Unified Messaging (UM) mailbox policy to apply a common set of UM policy settings, such as PIN policy settings or dialing restrictions, to a collection of UM-enabled mailboxes. UM mailbox policies link a UM-enabled user with a UM dial plan and apply a common set of policies or security settings to a collection of UM-enabled mailboxes. UM mailbox policies are useful for applying and standardizing UM configuration settings for UM-enabled users.
– Incorrect: After you create a Unified Messaging (UM) auto attendant, incoming calls to an external telephone number that a human operator would ordinarily answer are answered by the auto attendant.

Case Study 2 – Wingtip Toys (Question 68 – Question 77)
Overview
Wingtip Toys is a toy manufacturer and distributor in North America.
The company has a main office and two branch offices.
The main office is located in New York.
The branch offices are located in Boston and Chicago.
The number of users in each office is shown in the following table.

Existing Environment
Network Infrastructure
The network contains an Active Directory forest named wingtiptoys.com.
The New York and Boston offices connect to each other by using a 100-megabit per second (Mbps) WAN link.
The New York and Chicago offices connect to each other by using a 40- Mbps WAN link.
Exchange Server Infrastructure
The company has a Microsoft Exchange Server 2010 Service Pack 2 (SP2) organization.
All of the users in the New York and Chicago offices have Exchange Server mailboxes.
The users in the Boston offices do not have mailboxes.
The Exchange Server organization contains two servers.
The servers are configured as shown in the following table.

Lync Server 2010 Environment
The company has a Lync Server 2010 infrastructure that contains four components.
The components are configured as shown in the following table.

All of the New York and Chicago users use Lync services.
The Boston users only use IP-PBX phones. Only the New York users are configured for on-premises Exchange Server Unified Messaging (UM).
Voice Infrastructure
The hardware components of the current voice infrastructure are configured as shown in the following table.

At any given time, a maximum of 25 percent of the users in the New York office are on the phone. A maximum of twenty percent of the calls are to the PSTN.
Lync Online
The company is evaluating Microsoft Lync Online.
The company moves 20 Chicago users to a Lync Online subscription.
The subscription is configured to use a SIP domain of tailspintoys.com.
You did not implement directory synchronization or federation.
User Issues
Currently, all of the calls between the New York and Boston offices are routed through the PSTN.
User Issues
Currently, all of the calls between the New York and Boston offices are routed through the PSTN. The audio and video quality during web conferences between the Lync users in the Chicago and New York offices often is poor.
Inbound and outbound PSTN calls from the New York office are not redundant.
If a PSTN gateway fails, calls are not rerouted to another PSTN gateway.
Requirements
Planned Changes
The company plans to implement the following changes:
– Upgrade the Lync Server 2010 infrastructure to Lync Server 2013.
– Pilot Lync Online for 100 users in the Chicago office.
– Ensure that Lync Online users can find on-premises Lync users in the Lync Address Book.
– Ensure that Lync on-premises users and Lync Online users can communicate with each other by using instant messaging (IM).
Lync Server Requirements
The company identifies the following Lync Server requirements:
– Ensure that the New York users and the Boston users who have IP-PBX phones can call each other without using the PSTN.
– Improve the audio and video quality during the web conferences between the Chicago users and the New York users.
Unified Messaging Requirements
The company identifies the following Unified Messaging requirements:
– Pilot integrated voice mail in Microsoft Exchange Online for 100 New York users.
– Configure all users to have a five-digit extension.
– Ensure that users can retrieve their voice mail remotely by dialing +1 516 555 1212.
– Ensure that callers can reach the company directory by dialing +1 516 555 1213.
– Prevent users from receiving an email message when they miss a call.
Business Requirements
Three company executives require a second phone number for their existing Lync account.
This second phone number must not appear in any Lync address books or contact lists generated from Active Directory. Any planned changes must minimize administrative and financial costs.
Network Requirements
You identify the following network requirements for the planned deployment of Lync Server 2013:
– Limit the total bandwidth of all audio and video sessions from the Chicago office.
– Reduce the network utilization of Mediation servers.
– Prioritize Lync audio traffic on the network.
Enterprise Voice Requirements
Voice call routing in the New York office must be redundant.
All outbound or inbound PSTN call routes must not depend on a single component.

QUESTION 68
Hotspot Question
You are planning the deployment of two Mediation Servers in the New York office.
You need to identify the minimum number of network ports that must be configured on each Mediation Server.
The solution must meet the Enterprise Voice requirements.
How many ports should you identify? To answer, configure the appropriate number of network ports for the component in the answer area.

Answer:

Explanation:
Note: The Mediation Server translates signaling and, in some configurations, media between your internal Lync Server 2013, Enterprise Voice infrastructure and a public switched telephone network (PSTN) gateway or a Session Initiation Protocol (SIP) trunk. On the Lync Server 2013 side, Mediation Server listens on a single mutual TLS (MTLS) transport address. On the gateway side, Mediation Server listens on all associated listening ports associated with trunks defined in the Topology document. All qualified gateways must support TLS, but can enable TCP as well. TCP is supported for gateways that do not support TLS.
The main functions of the Mediation Server are as follows:
– Encrypting and decrypting SRTP on the Lync Server side
– Translating SIP over TCP (for gateways that do not support TLS) to SIP over mutual TLS
– Translating media streams between Lync Server and the gateway peer of the Mediation Server
– Connecting clients that are outside the network to internal ICE components, which enable media traversal of NAT and firewalls
– Acting as an intermediary for call flows that a gateway does not support, such as calls from remote workers on an Enterprise Voice client
– In deployments that include SIP trunking, working with the SIP trunking service provider to provide PSTN support, which eliminates the need for a PSTN gateway The following figure shows the signaling and media protocols that are used by the Mediation Server when communicating with a basic PSTN gateway and the Enterprise Voice infrastructure.
