Outdialing is a term used to describe the call-handling process that occurs when a UM-enabled user makes a call to an external phone number. Outdialing requires the following configurations:
- Dialing group rules
- Dialing rule entries
- Dialing restrictions
To enable outdialing for UM-enabled users, you must perform the following tasks:
- Configure the UM IP gateway to allow outgoing calls
- Create dialing rule groups/entries
- Configure dialing restrictions on the UM mailbox policy
As a Unified Messaging administrator, you will need to create appropriate dialing rules and properties for each location in your organization if you are going to allow outdialing. When you create a dialing rule entry, you will simultaneously be populating one of the two types of dialing rule groups: in-country/region rule groups or international rule groups. A dialing rule entry is used to define the telephone numbers and number masks for in-country/region and international calls that can be made by UM-enabled users who are associated with a UM mailbox policy.
Each dialing rule determines the types of calls that users within a dialing rule group can make. However, you must correctly configure the dial rule entry with a valid number mask and a dial number. After you create a dialing rule group and define the appropriate dialing rule entries on the Dialing Group Rules tab, you must add the appropriate dialing rule groups from the UM dial plan to a UM mailbox policy on the Dialing Restrictions tab.
Creating a Dialing Rule Entry
Use the following steps to create a new Dialing Rule Entry:
- Open the EMC with an administrator account that has the Exchange Organization Administrator role.
- Expand the "Organization Configuration" and click "Unified Messaging."
- Select the "UM Dial Plans" tab and then select a UM dial plan to edit.
- Click "Properties" in the "Actions" pane.
- Select the "Dialing Rule Groups" tab, then click the "Add" button under In-Country/Region Rule Groups or International Rule Groups.
- Provide the following information, below.
- Name: Select the name of an existing dialing rule group, or create a dialing rule group and type the name of the dialing rule group.
- Number mask: A number mask is used to limit the outgoing telephone numbers it will dial for a user. An example of a valid number mask is 91585xxxxxxx. This example will limit the user to just calls made to the 585 area code in the U.S.
- Dialed number: Your IP gateway vendor will expect to see numbers in a specific format. Use the Dialed number field to define in which format the number should be, especially if it is different from the numbers obtained by the Unified Messaging server. An example of a valid dialed number is 9xxxxxxx.
- Comment: Type a description of the dialing rule entry.
- Click OK to save your changes.
As an alternative to the EMC, you can also use the Set-UMDialPlan cmdlet in the EMS, like in the following examples.
For an in-country/region rule group:
[PS]C:>Set-UMDialPlan -Identity "Rochester NY" -ConfiguredInCountryOrRegionGroups US-NY-ROC, 91585xxxxxxx, 9xxxxxxx, "Valid Numbers for Rochester NY Office"
For an international rule group:
[PS]C:>Set-UMDialPlan -Identity "Rochester NY" -ConfiguredInternationalGroups "International, 901144*, 901144*, International Calls"
If you have complex dialing rules and a large number of dialing plans to configure, you may want to create a .csv file with the Name, NumberMask, DialedNumber, Comment headings and use the following cmdlet to import the file:
[PS]C:>Set-UMDialPlan "Rochester NY" –ConfiguredInCountryOrRegionGroups $(IMPORT-CSV C:CustomDialingRulesInCountryRegion.csv)
