This read-create Integer32, in seconds from 1 to 1000, sets the critical timer used during digit-map matching: it starts when the last digit needed for a match is received (assuming completion after expiry) if a digit map is in use, or starts immediately and cancels on the first digit entered if no digit map is used. Admins tune it to control how long the gateway waits before assuming dialing is truly finished. For example, an admin whose users often pause briefly between digits might raise this timer to avoid the gateway cutting off dialing prematurely.
