266 CHAPTER 4: USER CONFIGURATION
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
redirected 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.
Calls can be redirected from a Hunt Group extension.
You cannot add a TAPI Route Point extension to a Hunt
Group.
Hunt Group member A Hunt Group takes precedence over a Route Point. If a call
arrives on a Hunt Group member phone because it is a
member of a Hunt Group, a redirect is not permitted. If a
call arrives on the phone’s extension (not as a result of a
Hunt Group action), the call can be redirected.
Phantom Mailbox A call can be redirected to a phantom mailbox.
Mapped Line Calls that arrive through an incoming line that is mapped
to a line appearance button on a phone cannot be
redirected.
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 or from a phone that has a
bridged station appearance. Once a call to a primary
bridged station appearance reaches the secondary bridge
station appearance, the call cannot be redirected.
