Feature implementation 529

Permanent Hold

When a CLASS set is placed on permanent hold, the set is still treated as
though it is presented with a telephone call. The CLASS VMWI feature will
not send the VMWI message to the CLASS set to turn the visual indication
ON or OFF, until the set actually goes on-hook or the call is not presented to
the set. At this time, VMWI message is sent to the CLASS set to update
the visual message waiting status.

Set Relocation

When a CLASS set is relocated, the CLASS VMWI feature will lose the
message when the set finishes the relocation. An SCH1099 error message
is printed to indicate that the CLASS VMWI message is lost and no
automatic retry is attempted.
Feature packaging
The following packages are required for the CLASS VMWI feature:
•Message Waiting Center (MWC) package 46
•CLASS Calling Number Delivery (CNUMB) package 332, or
•CLASS Calling Name Delivery (CNAME) package 333, and
