Telephone Service (VOIP)
Finding an Extension
Have you ever needed an extension for someone not in your directory? Instead of calling around for someone’s extension, you can use Microsoft Outlook’s Address Book. Most extensions have been compiled by the Technology Department and they are available to all staff the same as everyone’s email address.
The following instructions will show Irving ISD staff how view/access these numbers and how to set phone numbers for your campus/department so you can see them in the Address Book in Microsoft Outlook.
