Hearing "tones" during some calls

[abward]

Mine mostly went away after support changed DTMF to Inband, and "lowered the gain on my line". Open and ticket and asked them to do both.

I still get it sometimes, a bit, on poor connections and/or particularly whinny-voiced females (not that there are many of those out there of course).

BTW: Features->Advanced has Very Low for both directions. I never changed these, and I am not sure if they changed when support lowered my gain.
