While an off-net call is undergoing call classification, any party who is not
already on the call will be unable to bridge onto the call. Also, the
originating party cannot release the call, conference anyone else onto the
call, or transfer the call to a new party. Once the call is answered off-net or
the call is returned to the switch for further call processing, then these
restrictions are removed.
If the last point in a coverage path is an off-net destination and no trunks
are available to route the call, the switch attempts to re-terminate the call to
the principal.
Avaya MultiVantage has no control over any redirection of the call that
may take place at an off-net destination. However, further coverage
treatment will be provided if the Off-Net Cvg Subsequent
Redirection/CFWD No Ans Interval field expires before the call is
answered off-net.
If the Coverage of Calls Redirected Off-Net field is not activated, the system does
not monitor off-net calls and bring them back for additional call-coverage
processing. In this case, once a call is directed to the remote call-coverage point,
the principal is dropped from the call. Effectively, the off-net coverage point is the
last coverage point in the coverage path.
VDN in a Call Coverage path
Assigning a VDN extension as the last point in a Call Coverage path allows the
functionality of Call Vectoring to be applied to a coverage point. The
programmable vector associated with the VDN effectively can provide great
flexibility in call handling. The integration of the Call Vectoring and Call
Coverage features can drive powerful AUDIX and Message Server applications.
For example, you can program the vector assigned to the VDN in the coverage
path to queue a redirected call to a messaging split for call answer operation and to
allow the caller to leave a message for the called principal. The same VDN also
can be used to retrieve messages. The vector program may also be varied by time
of day or split status to provide different types of coverage.
When a redirected call covers to a VDN, the principals simulated bridged
appearance is removed when vector processing begins.
When covered or direct calls are connected to AUDIX or a messaging split via
call vectoring, the original reason for redirection and the called principal must be
passed to the adjunct over the Switch Communication Interface (SCI) link.
