The following IP Office settings influence user dialing.  

• Dial Delay Count: Default = 0 (US/Japan), 4 (ROW)
  This value sets the number of digits dialed before the IP Office looks for a short code match.

• Dial Delay Time: Default = 4000ms (US/Japan), 1000ms (ROW)
  This value sets the maximum allowed interval between the dialing of each digit. If exceeded, the IP Office looks for a short code match even if the Dial Delay Count has not been reached.

• Off-Hook Timer
  When a user goes off-hook, the IP Office starts a 30 second off-hook timer (10 seconds in Italy). If the off-hook timer expires before a short code match occurs, the user is disconnected.

The following rules are used when short code matching is performed for user dialing:

• A short code is immediately an exact match is found.

• If no match is found but partial matches exist, the user can continue dialing,.

• If no match or partial matches are found, incompatible is returned.

• The following precedence is used to determine which short codes are used:

• Extension number matches override all short codes.

• User short codes override user rights and system short codes.

• User Rights short code matches override system short codes.

• When multiple exact matches occur,

• The match with the most specified digits rather than wildcards is used.

• If there are still more than one match, the match with the most exact length is used. This means X wildcards will override N when both match.
