Autodial remove last year

Hi new to Asterisk and AutoDialer I have a client that uses autodialer and their old MSP used to delete the previous year from the menu seems trivial to me but … does anyone have instructions to remove old years from the menu in autodialer?

No, and no. Because that is not an included module or something shipped with asterisk, so you need to check who developed the system, which version, what are they using etc. This forum is for Plain asterisk but we can try to help if you provide more information.
