The second column displays the user's device SIP registration status, which can be:
Green: SIP registration is present (user is connected to Wildix Collaboration or has a registered device, including TAPI, or is subscribed to push notifications has a push notification/ is actively using mobile app)
Grey: SIP registration is absent (user is disconnected from Wildix Collaboration and has no devices registered to his/her account)
Important: SIP registration status indication displayed in WMS - Users is not a substitution for Wildix Collaboration user presence status indication.
At the moment the status is grey, because users have no devices registered to their accounts and none of them is connected to Wildix Collaboration.
