Problem 10: The Mute and Volume Control buttons are disabled.
The Mute button and Volume Control buttons only work with 8411 telephones
and Callmaster VI telephones. However, the Mute button will not work with an
8411 telephone if an external speaker is installed.
Problem 11: During a conference call started by another caller, you are
unable to drop/hang up from the call while using the telephone handset.
If you are participating in a conference call that was started by another caller
(that is, you did not start the conference) and you are not using your
speakerphone, you will be unable to use Telephony Manager to hang up from
the conference. To hang up, you must place the handset back in the cradle.
Problem 12: During a conference call, the information in the Conference
Manager is not updated as participants drop from the call.
If you have a conference and participants hang up, the Conference Manager
will not update the information to reflect the participant(s) that dropped. If all
but one of the participants drop (that is, you are now talking to only one
participant), the Telephony Manager Switch Information area will change from
showing “CONFERENCE” to showing the information for the participant to
whom you are talking.
NOTE:
Once participants start dropping from the conference, the Drop Last
button in the Conference Manager may not work properly. Additionally,
if you are only talking to one participant, the Drop Last button will hang
up on that participant and then go off-hook again. Also, choosing the
Hangup button in the Telephony Manager window will display the
Confirm Drop Conference dialog box, even though you are no longer on
a conference.
