While working from home, a Skype for Business (S4B) extension allows you to make and receive calls through your computer and be identified as a University of Waterloo caller.

Requesting a S4B extension

Please have your department’s administrator submit a request for the new S4B extension. The request should be sent using this form: https://uwaterloo.atlassian.net/servicedesk/customer/portal/2/group/1618/create/3295 and include the following information:

• the work order to which the monthly charge and any long-distance charges should be applied

• username (your username is your 8-character UWaterloo username, i.e. j25rober@uwaterloo.ca)

• current phone extension of the user (if none, please indicate)

• location- building, room/cubicle number

Changing your 3xxxx extension to a S4B extension

• All S4B extensions begin with 4 (e.g 4xxxxx).

• If you currently have a 3xxxx extension at the University of Waterloo, we can migrate it to a S4B extension. The first digit of your extension would change to 4. For example, extension # 30300 would migrate to extension # 40300. If extension 40300 is not available, you will be assigned a different S4B extension number.

• Your telephone/desktop telephone will no longer be compatible with a S4B extension. Please review https://uwaterloo.atlassian.net/wiki/spaces/ISTKB/pages/1987444880

• Once your 3xxxx extension is changed/migrated to a S4B extension, this change will not be reverted back.

Creating a new S4B extension

If you do not have a 3xxxx extension at the University of Waterloo, we will assign you a new S4B extension.

Making a call

There are three ways you can initiate your call from Skype for Business:

1. Skype call

1. Enter their name in the Contacts search window.

2. Once you find the correct contact, you can hover over the contact and click call options in the drop-down next to the phone icon and select Skype call.

   Open

   

2. Dial by extension

Enter their UW extension in the Phone search window

Open

If you do not know their UW extension, you can search by their name.

3. Dial by phone number

1. Enter a phone number in the Phone search window.

2. Note: With a S4B extension, you do not need to enter “6” ahead of the phone number to make an off-campus call.

Voice mailbox for S4B extension

With a S4B extension, you will receive an email when there is a missed call and/or when there is a new voice message. You can find more detailed instructions on S4B extension voice mailboxes here: https://uwaterloo.atlassian.net/wiki/spaces/ISTKB/pages/280822987
