Subject: [PATCH v4 2/2] bluetoothctl: Add submenu for Call control profile testing
Date: Fri, 10 May 2024 02:18:39 +0300
Message-Id: <20240509231839.3005270-2-ajay.k.v@intel.com>

This adds submenu in bluetoothctl for CCP Testing with
options like answer and reject the active call. This feature
is tested with windows machine as CCP server which uses Teams
application to make calls
