Tenant-to-tenant access restrictions limit some features, such as Call Coverage. For example, the coverage of tenant 2 includes a telephone from tenant 3 in its coverage path. If tenant 4 has permission to call tenant 2, but does not have permission to call tenant 3, a call from tenant 4 to tenant 2 skips the tenant 3 coverage point.

You might also want to set up tenants with special access privileges. For example, you might give a restaurant in an office complex permission to receive calls from any other tenant. You might also want tenants to have permission to call, or be called by, building security, or those who administer and troubleshoot Communication Manager.

You can also assign all central office (CO) trunks to one tenant partition. All other tenants can then access the CO trunks.
