Hearing "tones" during some calls

[MisterEd]

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.

That's it! My sister ... definately a whinny-voiced female! 99.9% of the time it's on calls to her when this happens. Each time she gets married she gets more whinny.

Would changing DTMF to Inband have any other negative side effects?

Inband means the tones ride along with voice, and can be more subject to lost UDP packets. I would think its more forgiving than FAX transmissions.

If you have problems navigating interactive switchboards, you may need it switched back. That is my understanding - but I only know from what I've read on VoIP Forums ....

Out of band detects, and generates/synthesizes tones.
