have you assigned the phone in the valid device list:
Managing Sign In Devices
Attendants can only sign in to Cisco Unified Atte
ndant Console Standard using a valid Cisco device,
with a device name, extension and line number. For attendants to be able to make calls, the device must
also be associated with th
e Application User/End user configured in the Cisco TSP.
System administrators define which devices are availabl
e for attendants to use; these devices constitute
the
Device List
, which is accessible using
File > Options > Device List
. At start-up and during
execution, the appli
cation checks whether the devices in the
Device List are associated with the
Application User/End User configured in the Cisco TSP.
•
If they are not, they are marked as
invalid
. These have a lighter color in the list, and attendants
cannot make calls using them.
•
If they were previously marked as invalid, but are now associated with the Application/End user,
they are marked as valid, and attendants can make calls using them.
Administrators can either manually add devices to the list, or import them from CSV files.
While importing sign in devices from a CSV file, the
application checks that ea
ch device is associated
with the Application/End User configured in the Cisco TSP. If a device is not associated, it is shown as
invalid in the Device List.
If additional lines are later associated with a sign in device (using Cisco Unified Communications
Manager), they get added to the Device List. After these
changes, attendants will still be able to sign in
using the old extension
