Managed Mobility Access (MMA)
Up to 50 external numbers can be registered on your system to use Managed Mobi-
lity Access (MMA).
Every external number is assigned a fixed internal subscriber. Each internal subscri-
ber can be assigned more than one external number.
The internal subscriber can be given the option of using callback and editing his
numbers. Various registered numbers can have different editing permissions. This
means it is possible to, for example, allow callback for one external number only.
By default, a normal call divert can be activated to telephones with registered num-
bers. For each registered number, you can configure that twinning is activated
instead of call divert.
