    Menu Navigation based on DTMF Input Digits

    Hi All,

    I am trying to implement a menu navigation functionality based on the DTMF input digits. That is, user has to enter specific DTMF input digit to navigate through the Menu Tree. Following is how the Menu tree would be structured.

    Main Menu
    --SubMenu1(assign DTMF 1)
    --SubSubMenu1(Assign DTMF 1)
    --SubSubMenu2(Assign DTMF 2)
    --SubSubMenu3(Assign DTMF 3)

    --SubMenu2(Assign DTMF 2)
    --SubSubMenu1(Assign DTMF 1)
    --SubSubMenu2(Assign DTMF 2)
    --SubSubMenu3(Assign DTMF 3)

    --SubMenu2(Assign DTMF 3)
    --SubSubMenu1(Assign DTMF 1)
    --SubSubMenu2(Assign DTMF 2)
    --SubSubMenu3(Assign DTMF 3)

    I am clueless as to how to implement the menu functionality this way. The same DTMF input is assigned both in the Sub Menu context and Sub Sub Menu context. This could possibly raise a functionality issue because the application will have no idea as to which option to go next unless we hack around someway. That is, for example, when you press 1, how to decide where to go--Sub Menu option or Sub Sub Menu option. If you're in the Main Menu screen, you should be taken to Sub Menu option. On the other hand, if you are already in the Sub Menu screen, you should be taken to the Sub Sub Menu option.

    Thanks in advance.
