About the AT&T Collaborate app (User)

To help you stay in touch, the AT&T Collaborate SM service provides the Collaborate app, which comes in these versions:

  • Mobile Audio Only, with voice-only features, is included in each Basic Voice Seat.
  • Mobile is available with the Unified Communications (UC) bundle, which includes voice, video, and advanced communications features.
  • Tablet includes audio features plus more for tablets. This version is available only with the UC bundle.
  • Desktop includes audio features plus more, such as screen sharing and video conferencing, for desktop computers. Also includes the Microsoft® Outlook® add-in and Skype® for Business. Note that these 2 services don’t work together. If your administrator configures your Desktop app to work with your company’s Skype for Business service, don’t install the Outlook add-in. This version is available only with the Unified Communications bundle.

The Mobile and Tablet versions are available from the Google Play™ Store for Android® devices and from the Apple® App Store for iOS® devices. When you use the app on smartphones and tablets, you must upgrade to the latest version of the operating system for your device.

Android devices must have:

  • More than 1 core processor
  • 1GB or more available memory
  • ARMv7 instruction set
  • Screen resolution of 320×480 for smartphones and 1280×800 for tablets

Before you can download the app, your administrator must assign it to you when creating your profile in the Collaborate service. After the app is assigned to you, it appears in your Collaborate profile and on the Collaborate homepage.

When you install the Outlook add-in, you can view all your Collaborate app contacts in Outlook. You can also use Outlook to start a chat and make calls. Remember, you can’t use both Skype for Business and the Outlook add-in.

  • Group and view users in contact lists
  • Choose from more presence icons
  • Use the Outlook add-in to integrate Microsoft® Outlook® with Collaborate


Outlook add-in

The Outlook add-in works with the Desktop app to let you view the presence of your Collaborate contacts when you’re signed in to both the app and Microsoft Outlook. You can also use Outlook to view and use the Collaborate app features. For example, from Outlook, you can right-click an email in your Inbox to call or chat with the sender. When you read an email from someone on your Collaborate app Buddy list, you’ll see that user’s Collaborate presence noted with a green, gray, or red bar in the subject header. When you move the cursor over the contact’s email address, a window with Collaborate controls opens. From here, you can start a chat or make a voice or video call. To open the function you want in the Desktop app, click the corresponding icon in Outlook. You’ll see these options:

  • Chat
  • Call From Computer
  • Call From Phone
  • Video Call

You can also start chats and make calls with Collaborate contacts from their contact cards in Outlook.


Skype for Business

The Desktop app integrates with Skype® for Business. You can use Collaborate for non-Skype calls, such as calls to mobile while presence, chat, and Skype-to-Skype calls still take place through Skype.

Existing Skype integration with, for example, SharePoint, Office 365, and Internet Explorer can be used so that calls can be made from those apps.

Usual Collaborate call control features such as hang up, mute, transfer, conference, and Call Park are supported. Collaborate call logs and call settings are also available in this configuration.

Collaborate also updates phone presence on the Skype side. Collaborate must be started after Skype for calling to work smoothly.

Note: The Outlook and Skype for Business add-ins cannot be used at the same time.
