Calls not associated with a particular console group will be presentedto ACG 0.Tenant-to-tenant blockingIt is possible to define tables which allow or deny calls between tenant groupsin the same customer group. Normal intercept treatment is given to a stationattempting to dial into a denied access tenant.Tenant to tenant blocking is maintained across the network. Access is allowedor denied according to information defined on the node which currentlyprocesses the call.It is possible with network-wide tenant-to-tenant blocking to define one-wayrestrictions (“A” cannot call “B”, but “B” can call “A”), even though this isnot possible in standalone cases. If nodes do not have the sametenant-to-tenant restrictions defined, one-way blocking can result.Timed Reminder RecallsTimed Reminder Recalls work in the same way as in NAS, but on a tenantbasis. The attendant is chosen based on the tenant number of the target party.
