If an incoming call matches the ARS access code, it is routed to the
extension programmed for unassigned DID calls.
Barge-In can be used on a PRI line. Users cannot barge into data calls.
Call Waiting is provided on PRI lines at extensions so programmed. The
call-waiting tone is not blocked from PRI at an extension. Until the call is
answered, answer supervision is not returned to the network and the
caller hears a regular ringback instead of a call-waiting ringback.
Call Waiting does not work with data calls.
Callback cannot be used to request a busy PRI line assigned as a
personal line, but PRI lines in a pool are eligible for Callback. 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 callback 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 fails and a fast busy tone is applied.
Some applications (such as desktop video systems) that use data lines
may work improperly when releasing data facilities requested by
Callback.
The system does not support Camp-On onto data calls.
The system does not support conferencing onto data calls.
Data calls do not follow coverage delay settings. All data calls ring
immediately.
Outward and toll restrictions do not work with T1 lines emulating tie trunks
when the lines are set to Tie-PBX or Tie Switched 56 Data. Use
Automatic Route Selection or pool dial-out codes instead.
A PRI line that has been programmed for routing by dial plan cannot have
Remote Call Forwarding allowed. A T1 Switched 56 line cannot be used
for Remote Call Forwarding.
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 included in a calling group should not be programmed
for routing by dial plan.
Incoming calls on a line that is a member of a B-channel group
programmed for routing by dial plan are not eligible for answer by
Hands-Free Answer on Intercom.
Data calls cannot be placed on hold.
Music-On-Hold cannot be used with data calls.
