[asterisk-users] Detect #,* DTMF in dialplan

[shayne.alone at gmail.com]

Dear Mr,Ms;

I am planing for a custom IVR, for example to act as a simple installer!
I mean there is some choice  via 0-9 and # as *Next* and * as *Back* button.
is there any way for me to detect if the caller pressed # vs * on Dialplan ?
