PCM capture collection procedure

Procedure:
===========
1) Add to config:
- conf t
- voice hpi capture destination flash:pcm.dat
- voice hpi capture buffer 5000000

2) Then check which port the calls are active: (in enable mode)
- sh voice call summary
- show voice call status

            OR
- You can make the call go through from one channel

3) Start a capture on this port - please use:
(replace 1/0/0.1 with your channel and port found above)

- test voice port 0/0/0:15.1 pcm-dump caplog 7
(assuming you are on Pri 0/0/0:15 and the 1st b channel)

4) To stop the capture, please use:
- test voice port 0/0/0:15.1 pcm-dump disable

5) To reconcile the buffer and copy the PCM to the flash:
- no voice hpi capture destination flash:pcm.dat

6) Check you have the file in the flash:
- sh flash

Ensure you have a file listed called 'pcm.dat' with some size other than zero.
- (4 41096 pcm.dat) - for example.

7) Remove the buffer when the test is finished as it uses up DRAM
- conf t
- no voice hpi capture buffer 5000000
