 $History: MmiVoiceMemo.c

	Mar 28, 2007  DR: OMAPS00122762 x0039928
	Description: MM: Deleting a PCM Voice Memo message in one particular memory, 
	delete them in all memories
	Solution: voice memo position and pcm voice memo position is provided for all the devices.
	
Mar 31, 2006   ER: OMAPS00067709  x0pleela
Description: Voice Buffering implementation on C+ for PTT via PCM API 
Solution: Added prototype for voice_buffering_stop_recording
		Updating voicebuffering data for play stopped in play callback 
			
Mar 15, 2006   ER: OMAPS00067709  x0pleela
Description: Voice Buffering implementation on C+ for PTT via PCM API 
Solution: Defined new macro "PCM_VOICE_MEMO_MAX_DURATION" to restrict the recording 
			timeout to 20 secs for PCM voice memo and voice buffering
		Added prototypes of new functions inputVoiceMemoNumberEditor, voiceMemoNumberCB, 
			voice_buffering_tim_cb, voice_buffering_data_reset
		Added following new functions:
			pcm_voice_memo_play: Sets voice memo type to PCM_VOICE_MEMO which indicates 
									PCM voice memo is active and start playing the voice
			pcm_voice_memo_record: Sets voice memo type to PCM_VOICE_MEMO which indicates 
									PCM voice memo is active and start recording the voice
			voice_buffering_edit_num: Opens an edtor for the user to enter PTT number. Also resets
									voice buffering data with default values
			voiceMemoNumberCB: call back for number entry
			inputVoiceMemoNumberEditor: Settings of Editor
			voice_buffering_record_start: Starts recording voice and conects to the PTT number if the
										call is not active. If in call, then start playing the voice
			voice_buffering_record_stop: Stops the timer and recording. If call is not active the 
										disconnects the call
			voice_buffering_playback_start: Starts playing the voice. If any error while playing, 
										stops timer and recording
			voice_buffering_stop_recording: A wrapper function for record stop to invoke from other 
										modules. Stops the timer and recording
			voice_buffering_stop_playing: A wrapper function for play stop to invoke from other modules
			voice_buffering_tim_cb: Timer callback. Stops the timer. If PTT call is not setup disconnect 
									the call, else call record stop
			voice_buffering_data_reset: Resets voice buffering data to default values

		Function: voice_memo_play, voice_memo_record, voice_memo_destroy
		Changes: Added code to set voice memo type

		Function: voice_memo
		Changes: Added code to handle record start, play start for PCM voice memo

		Function: voice_memo_tim_cb
		Changes: Added code to handle record stop, play stop for PCM voice memo

		Function: voice_memo_riv_play_cb
		Changes: Added code to allow user to accept ant incoming call after the buffering phase
			
Feb 27, 2006    ER: OMAPS00067709 x0pleela
Description: Voice Buffering implementation on C+ for PTT via PCM API 
Solution: Defined a global variable gPcm_voice_Memo which indicates which Voice memo is active 
		and corresponding audio APIs will be invoked and duplication of code is avoided

Feb 24, 2006    ER: OMAPS00067709 x0pleela
Description: Voice Buffering implementation on C+ for PTT via PCM API 
Solution: Defined new macro PCM_VOICE_MEMO_MAX_DURATION which defines maximum 
			recording and playing duration for PCM voice memo and voice buffering
		Implemented following functions to support PCM voice memo feature
			pcm_voice_memo_init: Initialization of PCM voice memo
			pcm_voice_memo_exit:Termination of PCM voice memo
			pcm_voice_memo_play:Starts PCM voice memo play functionality
			pcm_voice_memo_record:Starts PCM voice memo record functionality
			pcm_voice_memo_start: create a new voicememo dialog
			pcm_voice_memo_create: Creation of window
			pcm_voice_memo_destroy: Destruction of an dialog
			pcm_voice_memo: Dialog function for PCM voice memo dialog
			pcm_voice_memo_win_cb:Callback function for information dialog
			pcm_voice_memo_tim_cb: Callback function for the PCM voice_memo timer.
			pcm_voice_memo_kbd_cb: Keyboard event handler
			pcm_voice_memo_riv_record_cb: Callback that handles the return status for PCM voice memo recording
			pcm_voice_memo_riv_play_cb:Callback that handles the return status for PCM voice memo palying
