How to change DTMF tone length on U319AA

I need the DTMF dial tones to be longer, in order to dial into my credit card & debit card 800 numbers to check balance, transaction history, etc. The default tone length is to short, resulting in missed or wrong numbers being sent to the respective automated systems.

Hey there @R_w_owen, we'll be happy to help you alter the DTMF tone length.


We recommend you try troubleshooting your device's sound settings by using the steps on that page to change the length of your DTMF tones. You can check the interaction controls options that are listed in the phone's user manual on page 188, such as the Touch & hold delay or Time to take action settings.

Please let us know if this helps.
