TAPI Route Points
User Configuration > TAPI Route Points
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 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 configure the external application to monitor it. When a call arrives at the route point extension, it is queued until the external application examines the caller ID information of the call, and then instructs the NCP to redirect the call to a destination configured in the external application.
NOTE: The destination of the call must be compatible with the dial plan of the NBX system or the rerouting of the call by the TAPI Route Point fails.

This table describes the behavior of TAPI Route Points and calls redirected by the external TAPI application.
Call Redirected to Description
Internal extension If the internal extension has activated Do Not Disturb, a call redirected to that extension goes immediately to the extension's Call Forwarding setting.
If the TAPI Line Redirect Timeout is set to a value greater than the extension's Call Forwarding setting and the call is not answered, the redirected call will be handled by the extension's Call Forwarding setting. The system will log a successful redirect.
External number Subject to the route point extension's Class of Service setting.
The call connects as soon as the external line resource (line card port, a PRI line, or a T1 channel) is acquired. The caller hears the call progress tones directly from the CO. At this point, the NBX system logs a successful connection. Calls to an external number cannot timeout, even if the call was redirected to a busy or an invalid number.
Call Park extension If a call has been previously parked at the specified Call Park extension, the redirected call is connected to the parked call.
If no call is waiting at the specified Call Park extension, the call returns to its original destination when the TAPI Line Redirect Timeout expires and the external application can redirect it again. After two failures, the call goes to the Call Coverage specified for the route point.
Hunt Group extension Calls redirected to a Hunt Group extension do not timeout. Once the call is passed to the Hunt Group, the system reports that the call has been successfully redirected.
Hunt Group member A redirect to a Hunt Group member is not permitted. If you redirect a call to a Hunt Group member, the call does not timeout. It fails and is routed back to the route point until the caller disconnects.
Phantom Mailbox A call can be redirected to a phantom mailbox.
The TAPI Line Redirect Timeout must be set to a value greater than one ring (approximately six-seconds) to allow the call to ring once and then be answered by the phantom mailbox.
Mapped Line A redirect to a line that is mapped directly to telephone line appearance button is not permitted. If you redirect a call to a mapped line, the call does not timeout. It fails and is routed back to the route group until the caller disconnects.
Bridged Station Appearance Calls can be redirected to a primary bridged station appearance.
A redirect to a secondary bridged station appearance is not permitted. If you redirect a call to a secondary bridged station appearance, the call does not timeout. It fails and is routed back to the route group until the caller disconnects.
