Sorry that program doesn't play them. I'm not sure what the proper import settings for sample, codec other setting are. I know TAC uses audacity to look at the wave forms of the pcm but i'm not sure if they are pre-converted or what setting they use to import the file.
The turn around time to send a file to cisco TAC and have them extract and listen to the file, sent it back to me and then I listed is much to long. I want to perform a test call and analise it on the spot for pri or pstn quality issues.
