yes disa takes some of the work offthe tva and if you had a 848 or a tda 50 you could sequence calls duing the day !! there is no dial mode in disa to intercept but i dont see were to define a destination for intercept you will have to test to see what happens on no digit dial it most likley rings a 0perator .what would be nice is if it dumped you at your top custom service menu , Shawn
