I'm skeptical that the toroid does much of anything but do have a few laying around. I guess it's worth a shot. Maybe I need to low pass filter my wife's voice using a speaker crossover!
The real solution here sounds like not replacing the tones generated at the phone & to just pass them through unaltered. I'm sure Ooma has a reason. I wish they would post it.
Some help may be on the way with the next firmware update due to arrive within the next few weeks. One item listed is:

As far as I know and experienced, this DTMF talkoff is an Ooma send problem (talking) and not a recieve problem (listening). If you hear this from others, it is others' phone carrier problem and not Ooma's.Morac wrote:For me getting a new phone won't help, since I hear this when other people talk.

The DTMF tones heard by one party or the other, during a conversation, are generated by one of the people's voice that is talking. The other person hears the tones. The DTMF tones can be generated by either party's voice.
The only other way the DTMF tones are generated are if someone at one or the other side of the conversation, hits the phone key pad.

Both my parents and I are using an OOMA Telo. I am hearing these tones while speaking with them, and they hear it on their end as well. It is absolutely ridiculous and has been this way for nearly a year now. How is this not fixed?
Ooma Telo firmware release 60080 Release Notes, which is delayed, mentions something about DTMF tones.
In the mean time, try adjusting your phone's audio down slightly on both ends of the call.
We had DSL which in our area could only provide 350 Mbps upstream. At first we kept getting disconnected frequently until I set the upstream bandwidth on our box to use only 256 Mbps of that. That solved the trouble with disconnects.
Still we had lots of audio drop-outs and this button press sound.
A month ago we upgraded to broadband with 500 Mbps upstream. I gave 400 Mbps to Ooma in it's settings.
Now the drop-outs gone, the touch tone sound gone. And I'd say the sound quality is hard to distinguish from the telco... even with hands-free.
