Features
Automatic Route
An incoming call can access Automatic Route Selection (ARS)
Selection
only through Remote Access, transferring, or Remote Call
Forwarding through ARS. A PRI line can be a member of a pool
that is accessed through ARS. Before ARS routes a call to a
pool, it checks whether one or more member lines in that pool
are available. If not, it selects an alternate pool so that the call
will not be blocked. Even if a B-channel is available when ARS
selects a pool with an available line, there may be none
available when it is time to send a Setup message to the
network. Or, after the Setup message is sent, the network may
determine that the B-channel proposed by the system is not
available. In either case, the call will fail and fast busy tone will
be applied.
If an incoming call matches the ARS access code, it is routed to
the endpoint programmed for unassigned DID calls.
A PRI line can be a member of a pool that is accessed through
ARS. Before ARS routes a call to a pool, it checks to see that
one or more member lines in that pool are available. If not, ARS
selects an alternate pool so the call will not be blocked, An idle
PRI line cannot be considered an available pool member unless
a check determines that it is associated with an available B-
channel. Even if a B-channel is available when ARS and
pooling select a PRI line, there may be none available when the
call is sent. In that case, the call fails and fast busy tone is
applied.
Barge-In
Barge-In can be used on a PRI line.
Call Waiting Call Waiting is provided on PRI lines transferred to telephones
so programmed. Call Waiting tone is not blocked from PRI data
endpoints if turned on. Until the call is answered, answer
supervision is not returned to the network, and the caller hears
regular ringback as opposed to Call Waiting ringback.
Callback
An incoming call on a PRI line cannot be Callback queued for a
busy line. A pool with PRI lines as members may be queued
for. An idle PRI line is not considered an available pool member
unless a check determines that it is associated with an available
B-channel. Even if a B-channel is available when the pool
selects a line for a queued call, there may be none available
when it is time to send a Setup message to the network. Or,
after the Setup message is sent, the network may determine
that the B-channel proposed by the system is not available. In
either case, the call will fail and a fast busy tone will be applied.
Group Calling
A PRI line that is a member of a B-channel group programmed
for Routing by Dial Plan should not belong to a calling group, A
line that is part of a B-channel group that is part of a calling
group should not be programmed for Routing by Dial Plan.
