Looking for DTMF for 9210i

Hi people, does anyone know where I can find the DTMF player/sender for 9210i or 7650. Thanks.

9210(i) supports DTMF sending in the telephone application. In a contacts item you can define a DTMF field, which is sent after connection, but it's also possible to bring up the DTMF box in the telephone application by selecting the third key to the right of the screen while you're making a phone-call (or select 'Send DTMF' from the 'Call'-menu.

Thanks for the reply, tried working with what you explained but couldnt find the 'third' button. In the Contacts Directory, I added a field for a contact with DTMF number, but apparently when I select the DTMF field, no menus are displayed. Even when you highlight the contact from the Telephone menu, it displays all numbers for phone call except the DTMF. So in otherwords, if you even set a DTMF number, how do you make a call?

Appreciate your help.
