DTMF tones

[sommerfeld]

Only during 2 calls with the same female friend. Always happened when she was speaking, and she wasn't hearing them, only me.

I've heard them during more than two calls with my fiancee; she was on the voipo end, I was on a cellphone.

I thought she was hitting buttons on the phone with her cheek. She says she was being careful to not do that.

Last night she was on the phone with her sister, and her sister was hearing them as well.

Update: I've changed the DTMF Method setting (Vpanel/Features/Preferences/Advanced) to InBand and reset the adapter. Let's see if it goes away..
