Any Internal caller does not
hear busy signal when
calling an internal station
in busy condition.(Busy
signal is not returned to
user when call is
immediately camped on
to another internal station
that is in busy condition.)
COS option Camp On Timer
is set to 0.
To correct
• disable Auto Camp on by
blanking Camp On Timer in COS,
or
• delay Auto Camp On by setting
COS option- Camp On Timer to a
value other than 0 (i.e. 10
seconds). By doing this, the call
still Camps On, but only after the
timer expires.
Any The volume setting saved
on the handset is lost.
The “Handset Volume
Adjustment - Saved”
parameter is set to “No”
Set the “Handset Volume
Adjustment - Saved” parameter to
“Yes” in the Class of Service
Options form.
The set is dual mode and the
volume was set at its
maximum. For hearing
safety, dual mode sets are
programmed to revert to their
default volume setting if they
are saved at maximum
volume
On a dual mode set, save the
volume at least one setting level
below maximum to ensure
that it will be saved.
Any Phantom calls are being
made to the operator.
When a user hangs up
without completing an
operation in his or her voice
mail box, the embedded
voice mail continues to
perform its function with
whatever portion of the
user's input is available,
even though the user has
hung up, and performs
off-hook dialing in attempt to
complete the operation.
Often, this results in calls to
0, usually the operator.
In the Class of Service Options form,
set the Multiline Set On-Hook
Dialing option to “No”.
Any Unable to put DID call on
hold.
If you have Record-a-call
Save Recording on
Hangup enabled, you won't
be able to put DID calls on
hold.
In the Class of Service Options form:
• Disable Record-a-call Save
Recording on Hangup.
