The error message
Agent line address number may not be empty!
is caused by an incorrect configuration sequence of TeamDesk. The AnyDevice line must be created before assigning a user to a TeamDesk. To fix the problem, proceed as follows:
- Remove user from all TeamDesks
- Remove the AnyDevice line via the wizard (select the user in the location > AnyDevice and softphone configuration)
- Re-create the AnyDevice line via the wizard (select the user in the location > AnyDevice and Softphone configuration)
- Add the user to the TeamDesk group
If the button to log in to TeamDesk is missing, check that the user has also been reassigned within the client (right-click on the hotline in the client > Show hotline details > Members tab).
