230 CHAPTER 4: U SER CONFIGURATIONA TAPI Route Point in the NBX system is an extension with a voice mailboxin the normal extension range:■ NBX V3000: 1000 – 3999■ SuperStack3 NBX: 1000 – 3999■ NBX 100: 100 – 449You create the TAPI Route Point, configure the NBX system to route callsto it, and then configure the external application to monitor it. Forexample, you can configure a line card port to send all incoming calls onthat line to a specific TAPI Route Point. When a call arrives at the routepoint extension, it is queued until the external application examines it andthen instructs the NCP to redirect the call to a destination specified in theexternal application. Typically, the redirect action is based on the caller IDinformation of the incoming call.Redirect Behaviors Table 29 describes the behavior of TAPI Route Points and redirected callswithin the NBX system.Table 29 TAPI Route Points and NBX System FeaturesCall Redirected to DescriptionInternal extension If the internal extension has activated Do Not Disturb, a callredirected to that extension goes immediately to theextension’s Call Forwarding setting.If the TAPI Line Redirect Timeout is set to a value greaterthan the extension’s Call Forwarding setting and the call isnot answered, the redirected call will be handled by theextension’s Call Forwarding setting. The system will log asuccessful redirect. If the TAPI Line Redirect Timeout is setto a value less than the extension’s Call Forwarding settingand the call is not answered, the call will return to theroute point. For more information, see “Specifying TAPILine Redirect Timeout” on page 233.External number Subject to the route point extension’s Class of Servicesetting.The call connects as soon as the external line resource (linecard port, a PRI line, or a T1 channel) is acquired. The callerhears the call progress tones directly from the CO. At thispoint, the NBX system logs a successful connection. Callsredirected to an external number cannot timeout, even ifthe call was redirected to a busy or an invalid number.
