Sorry for being so dense, but I am a little lost on this. I know that
both TDM (zaptel) and g.711u are 8khz, 8bit, mono, raw PCM, so it makes
sense that the sound file is best stored as a pcm file, 8khz, 8bit,
mono.

What I can not decipher is what file name extension should be used,
should it be a .wav file encoded at 8k/8b/mono? Or are you telling me
that it should be .ulaw

Patience please... I know I should get this, bit I don't!

Thanks a million.
