Do Not Disturb is not recommended since the device connected to an MFM
does not have an LED to indicate when the feature is active.
Forward and Follo Me (including Remote Calll Forward) are not recommended
W
on an MFM because the user does not have an LED that indicates when the
feature is active.
An MFM can be a member of a calling group, assigned as a delay
announcement for a calling group, or used to connect the calls-in-queue alert
for the calling group. An MFM used for the delay announcement or for the calls-
in-queue alert should not be assigned as a group member.
Calls cannot be put on hold on an MFM since the system ignores the switchhook
flash.
A single-line telephone with Message LED connected to an MFM can receive
message-waiting indications.
An MFM can be a member of a Night Service group. An external alert
connected to the MFM in the SAA operation, when assigned to a Night Service
group, can be used for supplemental ringing for after-hours call.
An MFM should not be a member of a speakerphone paging group.
An MFM user cannot park a call but can pickup a call parked by another user.
When personal lines are assigned or removed from the associated MLX
telephone, they should also be removed from the MFM when the device
connected is used to answer calls or provide supplementary ringing.
As a general rule, personal lines should be removed from MFMs unless the
device connected (such as a fax or a single-line telephone) requires a personal
line on which to make an outside call.
A single-line telephone connected to an MFM cannot be used for Power Failure
Transfer.
