Thanks for the telephone url -- I added it to the touch-tone
telephone instrument in clm-ins.scm (ugex.ins in CLM).

I never did nail down what that noise was -- it was affected by
what seemed to be an automatic gain control, and was much worse
on the calls to Australia and Las Vegas.  I was able to notch
out enough of it to be acceptable.
