[cisco-voip] pcm capture tools

Great find. A few clarifying points that were not clear to me:

* The feature is called "PCM Tracer" - note it is different from the original PCM capture.
* It is only on specific platforms - ISR-G2 and VG350.

Interesting.  I'll have to try this next time before I get TAC involved on a possible audio issue on one of our analog ports.

I saw the link below was included in the monthly Cisco Services Newletter that came out last week.   I haven't personally tried the commands or know whether it is equivalent to a PCM capture.

Negatory. There was discussion at some point but it's a legal minefield - warrantless tapping, liability, every privacy regulation, etc.

>From a technical perspective the decoder changes fairly often and it's not trivial to keep up with the changes as well as identify the DSP version it was captured on for accurate decoding. Though those are much easier to fix than the legal ones.

Is there a publicly available tool to work with the pcm.dat file from a PCM capture?
