Example If Digits 2 Min 4 and Max 4 the system knows that if the first digit is 2 it must collect no less than 4 and no more than 4 digits before making the call routing decision If the caller dials at least the minimum number of digits and not more than the maximum number of digits the system waits 5 seconds and then routes the call based on the digits dialed If the caller dials more than the maximum number of digits the system attempts to place the call Often Max value and the Min value are identical because you want the system to collect a specific number of digits no more and no less Example For internal extensions you want the system to collect exactly 3 digits 4 in a 4 digit dial plan before making a decision so you would set both Min and Max to 3 4 in a 4 digit dial plan The two columns may be different if the table entry applies to more than one situation Example In the United States the Min value for the 90 entry is 2 because 90 allows an internal caller to reach a telephone company operator 9 to get an outside line and then O to get the operator The Max value is 64 because the caller can continue to dial after the zero entering a number to call plus a telephone credit card number and possibly an identification code number If the caller dials only 90 which satisfies the minimum of two digits and stops dialing the system waits for 5 seconds If no other digits are entered the system conn

Route Points 265 TAPI Route Points Redirect Behaviors A TAPI Route Point is a virtual device within the NBX system where calls are held pending action by an external TAPI application Route points are typically used by call center applications to redirect calls A redirected call is one that is sent from its original destination the route point without being answered to a new location specified in the external application A TAPI Route Point in the NBX system is an extension with a voice mailbox in the normal extension range 1000 3999 for the SuperStack3 NBX 100 449 for the NBX 100 You create the TAPI Route Point configure the NBX system to route calls to it and then configure the external application to monitor it For example you can configure a line card port to send all incoming calls on that line to a specific TAPI Route Point When a call arrives at the route point extension it is queued until the external application examines it and then instructs the NCP to redirect the call to a destination specified in the external application Typically the redirect action is based on the caller ID information of the incoming call Table 50 describes the behavior of TAPI Route Points and redirected calls within the NBX system Table 50 TAPI Route Points and NBX System Features Call Redirected to Description Internal extension If the internal extension has activated Do Not Disturb a call redirected to that extension goes
