Hi, Attached is the patch to add call-volume interface for Ofono. It exposes two properties: 'SpeakerVolume' and 'MicrophoneVolume' to allow user could control phone volume through lower level driver. The ofono_call_volume_notify() is used to report call volume property change notification to the upper application.
The default volume could be stored in the modem.conf or query from remote. Each driver could report value in percentage to call-volume through ofono_call_volume_notify(). And then the call-volume will sync volume with remote side right after probe(). Please review it. Regards, Zhenhua
