1) Make a partition_A
2) Put that in CSS_A
3) Navigate to Call Routing---> Transformation ---> Call_Routing ---> Calling Party Transformation Pattern.
4) if you have 4 digit internal extensions.
make the pattern as XXXX
partition which your created partition_A
Calling Line ID Presentation as Restricted
5) Go to the phone where you wish to see unknown and in the device configuration page against
Remote Number Call party transformation CSS choose the CSS that you created.
OR
Apply this on the device pool level
