You have an Exchange Server organization that contains four servers. The servers are configured as
shown in the following table.
You are deploying Unified Messaging (UM).
You create a dial plan named UMPlan1 and a UM mailbox policy named UMPlan Mailbox Policy.
You need to ensure that all voice mail sent to the existing extension of a user is delivered to the
user’s mailbox.
Which three actions should you perform? (Each correct answer presents part of the solution. Choose
three.)
A.
Create a UM hunt group
B.
Create a UM IP gateway.
C.
Configure the IP-PBX to route calls to EX3 and EX4
D.
Configure the IP-PBX to route calls to EX I and EX2.
E.
Assign EX I and EX2 to UMPlan1.
F.
Assign EX3 and EX4 to UMPlan1.
Explanation:
* When you’re setting up Unified Messaging (UM), you must configure the IP PBXs on your network
to communicate with the Client Access servers running the Microsoft Exchange Unified Messaging
Call Router service and the Mailbox servers running the Microsoft Exchange Unified Messaging
service in your Exchange organization. You must also configure the Client Access and Mailbox servers
to communicate with the IP PBXs.
C: A Unified Messaging (UM) IP gateway represents a physical Voice over IP (VoIP) gateway, IP
Private Branch eXchange (PBX), or session border controller (SBC) hardware device.
* Here are the basic steps for connecting VoIP gateways, IP PBXs, SIP-enabled PBXs, or SBCs to Client
Access and Mailbox servers:
Step 1: Install the Client Access and Mailbox servers in your organization.
Step 2: Create and configure a Telephone Extension, SIP URI, or E.164 UM dial plan.
Step 3: Create and configure a UM IP gateway. You must create and configure a UM IP gateway for
each VoIP gateway, IP PBX, SIP-enabled PBX, or SBC that will be accepting incoming calls and sending
outgoing calls.
Step 4: Create a new UM hunt group if needed. If you create a UM IP gateway and don’t specify a
UM dial plan, a UM hunt group will be automatically created.
Incorrect:
B, D:
The question states, “You need to ensure that all voice mail sent to the existing extension of a user is
delivered to the user’s mailbox”. The dial plan is therefore a Telephone Extension dial plan. Client
Access and Mailbox servers cannot be associated with Telephone Extension or E.164 dial plans.
E and F are wrong, as the explanation says (for B and D which is wrong), servers cannot be associated with Telephone Extension or E.164 dial plans (they can only be associated to SIP URI plans).
D is wrong, you must route calls to CAS’s and not mailbox servers.
So A, B and C are correct.
In previous versions of Exchange, the Unified Messaging server had to be added to a UM dial plan. In Exchange 2013, Client Access and Mailbox servers can’t be associated with a Telephone extension or E.164 dial plan. Client Access and Mailbox servers will answer all incoming calls for all types of dial plans. However, if you’re integrating UM with Microsoft Lync Server, you must add all Client Access and Mailbox servers to all SIP URI dial plans to enable call routing to work correctly with Lync Server.
