Annoying DTMF Tone

[tlc]

Hello! I have a problem with DTMF tones on T22P. When there is a phone call, you can hear the annoying DTMF tones, if most callers are women.
I tried to use these settings:
Sending DTMF tones is set to RFC 2833 ed the ip phone:
Button Sound Disabled
Send Sound Disabled
Min Delay 0
Max Delay 300
Normal Delay 120

But do not work.

If you press the keys the recipient hears the tones
If you do not press the keys the recipient hears the tones randomly.

Hi tlc,

Go to webpage->Account->Advanced, choose DTMF Type as SIP INFO and test again.
