Hi Victor,
I don't think this feature is supported on the 7960 IP Phone model;
Unified CM Call History Presence
Unified CM supports presence capabilities for call history lists (the Directories button on the phone). Call history list presence capabilities are controlled via the BLF for Call Lists Enterprise Parameter within Unified CM Administration. The BLF for Call Lists Enterprise Parameter impacts all pages using the phone Directories button (Missed, Received, and Placed Calls, Personal Directory, or Corporate Directory), and it is set on a global basis.
Presence capabilities for call history lists are supported for both SCCP and SIP on the following Cisco Unified IP Phones:
â¢Cisco Unified IP Phones 7941G, 7941G-GE, 7942G, and 7945G
â¢Cisco Unified IP Phones 7961G, 7961G-GE, 7962G, and 7965G
â¢Cisco Unified IP Phones 7970G, 7971G-GE, and 7975G
The Cisco Unified IP Phones 7905G, 7906G, 7911G, 7912G, 7940G, and 7960G do not support presence capabilities for call history lists.
From this CCM 6.x SRND Guide;

Hope this helps!
