In order to permit extension number calling between members of a BG, the BG numbering plan must be configured with the appropriate Prefix access code (New destination code table entries and Extension table entries).
In the basic scenario where there is only one customer location
(site), the common BG numbering plan defined above (for example, using the Quick Add Business Group wizard) will suffice as the one and only BG numbering plan.
If there are multiple locations
, and the planner has decided to accommodate site specific routing by providing multiple numbering plans for the BG, the common BG numbering plan has a reduced function. It is typically used as follows, in this case:
To define the numerous feature access codes (* and # codes) that will be common to all sites
To provide access to common resources within the BG, such as PSTN gateways that can be accessed by all sites for long distance calls
The scenario described here assumes a single BG numbering plan is sufficient.
