Explanation

The T302 inter-digit timeout timer in ISDN (and in Cisco UCM digit analysis) defines how long the system waits for additional digits before proceeding with call routing. When 'Urgent Priority' is enabled on a Directory Number in Cisco UCM, the system immediately routes the call as soon as a complete pattern match is found, without waiting for the T302 timer to expire. This is configured per-DN in the directory number settings. This is particularly important for numbers that could be prefixes of longer patterns - urgent priority forces immediate routing upon a best match, improving post-dial delay for users.
