thanks for your information

do you mean DTMF tone not working when 29 keys are all set to Type DTMF ?

if yes, please check the "play DTMF tone" enabled or not , web page path :

Features -> General Information -> Play Local DTMF Tone

or do you mean the DTMF Tone can work, but when press it , it will not function as you expect , if yes, you can try to change the DTMF type and test again, web page path :

Account -> Advanced -> DTMF Type
