Account codes cannot be entered on calls made via Remote Access.
An Allowed List is one of the class of restriction (COR) items for Remote Access.
When barrier codes are not used, Allowed Lists are assigned to lines/trunks
system wide. When barrier codes are used, Allowed Lists are assigned to
individual barrier codes.
Remote Access users can make calls by using ARS. The user dials into the
system, enters a barrier code if one is required, and dials the ARS code while
listening to system dial tone. FRLs can be assigned to restrict the routes that
remote callers can use. When barrier codes are not used, an FRL is assigned to
all lines/trunks and cannot be assigned to individual lines/trunks. When barrier
codes are used, FRLs are assigned to individuals barrier codes.
If the system is programmed for Remote Access Callback, Remote Access
users can use Callback. The user cannot hang up but must wait on the line until
the extension or trunk pool is available. The user hears Music-on-Hold if it is
programmed.
Invalid Remote Access calls can be programmed to ring on an Intercom or
System Access button on a DLC.
Disallowed Lists are assigned as one of the items of the class of restriction
(COR) for Remote Access. When barrier codes are not used, Disallowed Lists
are assigned to lines/trunks system wide. When barrier codes are used,
Disallowed Lists are assigned to individual barrier codes.
Calls received via Remote Access show standard call information for outside
calls, including the caller's number if automatic number identification (ANl) is
available. If a Remote Access call is sent to Coverage because an invalid
number was dialed, an MLX display telephone user who receives the call sees
the "Cover DISA#?" message.
Forced Account Code Entry cannot be assigned to Remote Access users.
Users can set up forwarding of calls to extensions or outside telephone numbers
via Remote Access. To do so, the user calls into the system on a line/trunk that
is programmed for Remote Access. If a barrier code is required, the user hears
the Remote Access dial tone (stutter tone) and enters the barrier code. Once the
barrier code is correctly entered or if barrier codes are not required, the user
hears system dial tone.
