Re: voip is digital - why use an ata?

said by rblizz:

I'm lucky enough not to have had any echo issues with my ATA. Not sure what DTMF "talk-off" is. I realize that not every ISP and router is the same, though.

DTMF talk-off is when your ATA mistakes sounds that it hears (i.e. your voice) for you pressing buttons on your phone. When this happens, the ATA will send the tone through. Very annoying to the person on the other end!

Thanks. I guess I'm lucky enough not to have had that issue either.

DTMF talk-off issues predate VoIP.

Bell Labs was concerned about this decades ago, and many companies since then....

Female voices are more likely to trigger.

And, the change in a woman's when she gets pregnant can trigger this in certain systems. My brother was working with a tech where this problem suddenly cropped up. He asked, "this is going to sound strange, but are you pregnant?" "Yep." I would have never had the guts to ask. (I hadn't heard the term "DTMF talk-off" but I'm aware of the issue.)

Amazing.

Here's a recent study.

Pregnancy and voice: changes during the third trimester.
