Tip

Lync-to-phone supports dialing using full E.164 phone numbers only; abbreviated dialing using office extensions is not available with this service. For example, 415-123-4567 is a valid number to dial, but 4567 is not. This means that the number of digits specified for the SIP URI dial plan should include the area code and prefix, which would be 10 digits in this example.

6. Use the drop-down menu to select a Dial plan type of SIP URI, and select the Audio language that will be used for the service.

7. Enter the Country/Region code for the dial plan to enable domestic and international dialing; for example, the correct region code for the United States is 1.

8. When finished, click Save.

If necessary, after the SIP URI dial plan is created, you can edit additional properties by selecting the dial plan in the UM dial plans page of the Exchange Admin Center, and clicking the Edit icon. For example, additional properties of the SIP URI dial plan that can be configured include minimum PIN length, limits on personal greetings, Outlook Voice Access settings, and much more.
