[asterisk-users] Read one or X DTMF

[Ruddy Gbaguidi]

Hi all
I'm just having a problem now and I don't have any idea how to do this.

It is pretty simple. When a customer calls, to speed up the navigation 
in the dialplan, I want something like

"Welcome. Please enter your 10 digit customer number or press * to register"

So, I want to read up to 10 digits, and if the user press *, I want to 
go to the next extension.

Do you have an idea ??
