■ DCS — Leave Word Calling (external only)
In a DCS network, the called party may be on a different switch than the
calling party. If the DCS link is down, attempts to store Leave Word Cancel
messages are denied and intercept tone is returned. LWC requests are
always denied for principals with AUDIX LWC; in some instances, the
request to cancel LWC may appear to be active when it actually is not.
When the local switch communicates with I
NTUITY AUDIX via mode
codes, I
NTUITY AUDIX cannot support remote DCS switches.
■ Facility Test Call
Unauthorized calls can be placed using the facility test-call access code.
To prevent toll fraud, remove the facility test call access code.
■ Leave Word Calling (LWC)
You can have a principal’s LWC messages kept by AUDIX. The principal
can retrieve a message by calling AUDIX. The principal cannot retrieve the
message using other retrieval methods, but is notified of its existence by
AUDIX.
For other messaging services, you can have AUDIX report the existence of
waiting LWC messages for the principal, but not the message content. The
principal can retrieve the message using other retrieval methods, but is still
notified of the existence of AUDIX messages.
If the data link between the system and AUDIX is down, attempts to
activate LWC for an AUDIX-covered principal are denied and reorder tone
is returned.
If a caller attempts to cancel a LWC message sent to AUDIX, the caller
receives intercept tone if the called party is on the same switch. The caller
receives confirmation tone if the called party is on another switch in the
DCS network as long as the DCS data link to the called party’s switch is
operational, even though the message is not actually canceled.
When the local switch communicates with I
NTUITY AUDIX via mode
codes, I
NTUITY AUDIX does not accept or store LWC messages in user
mailboxes.
■ Ringback Queueing
Ringback Queueing does not apply to AUDIX calls. On direct calls to a
remote AUDIX, if all trunks to the host AUDIX are busy, busy tone is
returned. On coverage calls, if all trunks are busy, AUDIX is treated as a
busy coverage point. If there are coverage points after AUDIX, then the
call terminates at those points.
