Might be a cluedge work around but it seems to me you could ask the user for a
key press and set a var based on receiving the keypress or not. Something to
the effect of:
exten => x,x, Dial(cell_phone,20);
exten => x,x, Read(var|voice_prompt|1);
exten => x,x, GoToIf($[${var} = 9]?extension if key pressed:extension if key
not pressed);
Voice prompt should say "blah blah press 9 to accept this call".
Read wiki for the Read and the GoToIf commands.
