Why doesn the user see the Resume key on the desk phone after hanging up the cellular phone for desk pickup?
A. The problem could be due to the cellular phone service provider. When disconnecting a call for the cellular phone, some cellular providers play a tone (similar to a busy tone) instead of sending a disconnect signal to Cisco Unified CallManager. Cisco Unified CallManager cannot detect the call hangup; the other party hangs upon hearing the tone. Because the call has not been disconnected immediately, the desk pickup feature cannot work.
