Configuring a Subscriber Access Number

If the Outlook Voice Access feature of Exchange UM will be used with Lync Online, each subscriber access number used must be added to the Exchange UM dial plan, and also must be configured as an access number within Lync Online. Use the following procedure to configure a new subscriber number for the Outlook Voice Access feature using the online portal:

1. Log on to the Office 365 Portal.

2. On the main page, click the Admin tab at the top, and then select Exchange from the drop-down menu to open the Exchange Admin Center.

3. On the left side, click Unified messaging, and then click on UM dial plans at the top.

4. At the UM dial plans page, select the SIP URI dial plan previously created from the list, and click the Edit icon.

5. At the Dial plan properties page, under UM Dial Plan, click Configure.

6. On the left side, click Outlook Voice Access.

7. At the Outlook Voice Access page, under Outlook Voice Access numbers, enter the phone number that users will dial to sign in to their mailboxes, using the full E.164 numbering format (for example, +14151113333). The number of digits entered should also match the number of digits associated with the dial plan. After the number is entered, click the plus symbol to add the number to the list of Outlook Voice Access numbers. This step can then be repeated as many times as necessary to associate additional numbers with this same dial plan if desired.

8. When finished, click Save, and then click Close at the Dial plan properties page to return to the Exchange Admin Center.

9. Click the Admin tab at the top, and then select Lync from the drop-down menu to open the Lync Admin Center.

10. On the left side, click Lync-to-phone, and then click on Access numbers at the top.

11. At the Access numbers page, click on the plus symbol.

12. The Access numbers properties page appears, as shown earlier in Figure 22.13. Enter the same phone number that was configured for Outlook Voice Access in step 7, again using the full E.164 numbering format.

13. Under Address, enter a unique prefix for the SIP address that will be associated with the subscriber access number, such as CompanyABC_SubscriberAccess, and then use the drop-down menu to select the SIP domain that will be associated with this subscriber access number.

14. If desired, enter a description to clarify the purpose of this auto attendant in the Description field.

15. Under Type, select Outlook Voice Access, and then click Save. The new subscriber access number, along with any auto attendant numbers previously configured, are displayed in the list of access numbers configured for Lync Online, as shown in Figure 22.14.
