asterisk users - Apr 2005 - Does ztmonitor record the audio channel?

Hi,

I'm trying to debug cid information coming from an analog PSTN line using
ztmonitor to record the call using the following command line:

./ztmonitor 1 -v -f call.raw

This works fine, I see visually the audio rx and tx bar, the file call.raw
was created but the length of this file is allways 0 with no data.

Is anything I am doing wrong? Any hint about using ztmonitor?

Thanks
