Read the documentation for the Dial command, specifically the 'g' option. 
Place a DISA command (with no password) as the next priority in the 
context.

With some timeouts in the context called from the disa application and a 
chain of contexts (one for each timeout) this should be doable. I'm not 
sure what you mean by "locking out". For a permanent lock you will need to 
store that information in the AstDB or an external database. Otherwise 
just Wait().
