Create a UM IP Gateway
Although
the dial plan might represent the logical grouping of users within
Active Directory, the UM IP Gateway represents the actual, physical
connection between the Unified
Messaging server and the physical gateway (IP-PBX or IP Gateway). UM IP
Gateway creates a logical connection that links the IP Gateway device
with a UM hunt group.
To create a UM IP Gateway, perform the following:
1. | Open the EMC.
|
2. | From the Navigation Tree, expand the Organization Configuration work center, and click Unified Messaging.
|
3. | From the Actions pane, select New UM IP Gateway to open the wizard, shown in Figure 1.
|
4. | Provide a name for the UM IP Gateway.
|
5. | Select the radio option to provide either of the following:
|
6. | Select
Browse, and choose a Dial Plan. (After a dial plan is selected, a
default hunt group is created to associate this new UM IP Gateway to
the specified dial plan.)
|
7. | After the wizard is complete, select Finish.
|
After
the UM IP Gateway is created, you can right-click the Gateway and go to
the properties. The properties are the same as what we saw during the
wizard creation; however, the Allow Outgoing Calls Through This UM IP
Gateway is selected by default.
Beneath
the UM IP Gateway, a default hunt group has been created. A hunt group
represents a connection between a UM IP Gateway inbound call number and
a UM dial plan. It associates that dial plan with a pilot identifier.
The pilot identifier is an ID that is configured on the PBX or IP PBX.
It can also be an extension number or SIP URI, depending on your IP
PBX. So you might configure extension 5200 as the pilot number on the
PBX. When a call comes in for that extension, it looks to see where it
can deliver the call—perhaps 5201, 5202, and so on.
From
a physical perspective, a hunt group is a grouping of lines. There is a
group of extensions that a caller has available to him, and when he
calls, he goes through the hunt group to gain access to that group of
extensions. A line will usually be available if you have enough lines
in your hunt group.
To create a new hunt group, perform the following:
1. | Open the EMC.
|
2. | From the Navigation Tree, expand the Organization Configuration work center and click Unified Messaging.
|
3. | Select the UM IP Gateways tab.
|
4. | Locate the UM IP Gateway you wish to create the hunt group in and select it.
|
5. | From the Actions pane, select New UM Hunt Group to open the wizard.
|
6. | Provide the name of the hunt group.
|
7. | Select the Browse button to locate the Dial plan.
|
8. | Type in the pilot identifier that relates to your device.
|
9. | Click New.
|
10. | When complete, click Finish.
|
Note
It is important that you define the pilot number correctly; otherwise calls will not be answered and call routing fails.
