/**
*
* @class	RAnsPhonePhone AnsPhonePhone.h
* @brief	This class modifys the speaker volume and microphone gain of the phone
* This is necessary, because the CMdaAudioRecorderUtility does not use the TDeviceMode
* correctly, when it is set using SetAudioDeviceMode()..
*
* To set the speaker and microphone volumes, we use a Set() function from
* RTelSubSessionBase, which RPhone derives from. These are protected functions in
* RTelSubSessionBase so we must derive from RPhone in order to use them.
* The Set() functions work by passing in the appropriate id, which signifies setting
* the speaker volume or microphone gain, and a TInt (the volume/gain) packaged into a descriptor.
