Core Issue
Cisco CallManager Express allows administrators to associate pickup groups with individual ephone-dn entries, making it easier for phone users to answer or pick up a call that is ringing on a different ephone-dn. If both ephone-dns are in the same pickup group, the user presses fewer keys to pick up the call.
Resolution
Most of the time, these issues are caused by using a load not recommended for Cisco CallManager Express 3.3. For more information, refer to Cisco CallManager Express 3.3 Supported Firmware, Platforms, Memory, and Voice Products. The document contains a compatibility table for Cisco CallManager Express with other loads. It includes information on downloading compatible loads, such as file P00305000600.sbn.
The user must delete the old file from Flash after copying the new one there. Change these commands to point to the correct new load file name:
- Globally: tftp-server flash:P00305000301.sbn
- Under telephony-service: load 7960-7940 P00305000301
Reset all phones, and type create cnf under the telephony-service command line, making sure that the new load is sh ephone phone-load.
Note: If you have other IP phone models, make sure they are running compatible loads as well.
