Creating a Calling Search Space
What is a calling search space? It is a list of partitions that can be accessed by
users so they can place a call.These calling search spaces are only allocated to
telephony devices that can start calls. Once implemented, it is simple to create
and use dialing restrictions because users are only allowed to dial those partitions
in the calling search space they are assigned to. If the user tries to call outside the
allowed partitions, they receive a busy signal.
For all intents and purposes, the calling search space is what allows callers to
complete connections for their calls.You would often use this configuration
when setting up office call policy. For example, when you set up office phones,
you often allow them unrestricted dialing abilities. Lobby phones, on the other
hand, can usually only call other phones located in the office.To establish these
criteria, you must create a partition for the office users, in this case SE-Users (see
Table 9.6). All calls destined for the PSTN would have the route pattern 9, and
those calls would be placed within the SE-PSTN allocated partition.Two calling
search spaces would then need to be created to represent the two sets of dialing
characteristics (see Table 9.7).
