You can also configure the type of notifications you want to receive with Collaborate:

  • Allow Notifications
  • Show in Notification Center
  • Sounds
  • Badge App Icon
  • Show on Lock Page

We recommend that you turn on all of these notifications. We also recommend that you set the option Alert style when unlocked to Alerts.


Screen Share

The Collaborate app for iPad supports Screen Share as view-only. When you send a Screen Share invitation from Desktop, the badge notification appears on the main bar and in the Chat list view. When you select the entry with page sharing from the Chat list, a communication pane opens with share by default. You can return to the chat or call (if present) with a swipe. When sharing is paused, the page share view remains active and shows the last image that was shared.

You can view page share in all communication modes:

  • My Room
  • One-to-one chat
  • Ad Hoc group chat room (multi-user chat)


You can search in Collaborate Contacts, your phone’s address book, and the directory. The search appears in a separate input field on the Contacts tab. When you select a filter (All, Online, Local Address Book, or Directories), search results show contacts from only the current selected category.


Multi-device support

The app supports users who have multiple devices in these ways:

  • Chat invitations are sent to all your devices. Before the session is accepted, messages are sent to all devices. When answered, the chat messages go to the device that has sent a reply message.
  • Retrieving your own presence notifications when another app updates your presence. The app updates its own status based on the information it receives from the server.
  • Accepting a shared presence invitation in one app is also recognized by another app, and both apps start receiving presence updates.
  • A new presence subscription made in one app is recognized in another. If the contact blocks the invitation, the server sends presence notifications to all your apps to indicate that the subscription was terminated. You also see this information. If the app receives 2 presence authorization requests from 2 or more devices for the same user, it shows only 1 request.
  • Removing a contact from a Contacts list in one device is recognized in another app, and the Contacts list is updated in both apps.


Other features

Manage privacy

When you add contacts to the Contacts list, these contacts receive a New Subscriber dialog box that asks whether they’ll allow you to see their presence. This information is stored in this contact’s presence policies.
