Busylamp not working, CKEM 36 connected to a Cisco 9971 phone

Hello,

We have recently installed a new Phone model for our reception desk. Its a Cisco 9971 video Phone with an extension module connected (Cisco CKEM 36). I have configured the extension module with busy lamp fields with call pickup. The reception is able to pickup calls using the extension module, but is not able to see if lines are busy. The lamp wont light up. Our callmanager is at version 10.5.

Is there a known issue with the CKEM 36 not showing busy lines ? Are there things I could verify in the configuration ?

Thank you in advance

You can program feature key buttons on the Cisco Unified IP Color Key Expansion Module as a directory number, line key, or speed-dial key. The buttons are illuminated, and when configured as a directory number or shared-line keys they allow for easy identification of call state. This capability provides features that are similar to those of typical direct station selection/busy lamp field (DSS/BLF) modules but are not intended to be directly comparable to those of traditional DSS/BLF modules. The Cisco Unified IP Color Key Expansion Module is neither an operator nor an attendant console. Its primary function is to provide the Cisco Unified IP Phone 9971, 9951, and 8961 models with additional keys for features such as speed dial or directory numbers. The illuminated buttons make it easy to determine line status, making the Cisco Unified IP Color Key Expansion Module an ideal call-coverage tool.
