This read-write Integer32 object, in seconds (10-10000), sets the partial dial timing used with a digit map as the inter-digit timer; it starts only after the first digit and restarts after each subsequent digit until a digit map match or mismatch occurs. This timer determines how long the system waits between dialed digits before deciding the caller has paused too long mid-dial. An engineer tuning dial-plan responsiveness for a slow-dialing user population would extend this timer so calls aren't prematurely timed out between digits.
