Hello aapexisinc,
I think there are 2 ways to capture this information
A.- Manual procedure to capture the call using WireShark:
A.1. Use WireShark to capture the RTP between the gateway and the phone when the call is disconnected the busy tones are playing and then save the G711ulaw payload in .AU format.
A.2. Load the audio file into cooledit96 (freeware audio editing application) and use the cursors to determine the on times and off times of the tones.
A.3. Select the Analyze option to do a frequency analysis. From the new window, you can move the cursor over the frequency peaks to determine the component tones. Round the frequency to the nearest 5hz. Measure the on time of the tone and the off time of the tone to determine the cadence.
A.4. Use these measured values to create a custom disconnect tone class
B.- Via PCM Capture (which can be collected mannually (via OOB) or via CCA
First you need to create logger buffer
voice hpi capture buffer 10000000 ( you need a big buffer before log file is open )
second create log file
voice hpi capture destination tftp://a..b.c.d/filename (Filename must end in .dat)
or
voice hpi capture destination flash:filename
test voice port x/y/z pcm-dump caplog < pcm stream index> duration
the PCM stream you can use 7 to record all tone. Duration can be 0 to record the PCM during the life of the call.
test voice port 0/2/0 pcm-dump caplog 7
after end of the call. Stop the trace
test voice port 0/2/0 pcm-dump disable
stop recording by remove log buffer
no voice hpi capture buffer
and here is the procedure via CCA.

-PCM Capture Diagnostic. From the PCM Capture window (Troubleshoot > Telephony Diagnostics > PCM Capture), you can perform a PCM capture to troubleshoot audio issues such as poor voice quality, one-way audio, or no audio.
once you captured you PCM File, please send me this file (vcappucc@cisco.com) and i will more than glad to provide you with the code you need to issue on your UC device
example:
voice class custom-cptone CPTONE-CUSTOM
dualtone disconnect
frequency 400
cadence 400 350 230 520
Then in the FXO Ports:
voice-port 0/x/y
supervisory custom-cptone UAE-CUSTOM-ALCATEL
supervisory disconnect dualtone mid-call
timeouts call-disconnect 5timeouts wait-release 5
Thank you
Victor.-
