"Call as" Functionality
If configured you may have the option to make a call as a service. When selected your outbound calls will look like they come from the service directly (using the Contact Center's SIP Address or Tel Number) instead of your own contact information.
This setting lasts until you reset it manually or restart the Agent Assistant or Lync/SfB Client. If you wish to keep the "Call as" service selection even after restart of the Agent Assistant or Lync/SfB Client you can select the "Save last Service Selection" option in the Agent Assistant Settings.
