220 Call Park
Call Waiting
A recall of a parked call is not presented in the Call Waiting mode. If an
internal telephone is in the parked state, Call Waiting to that telephone
is not provided.
Centralized Attendant Service
Call Park is limited to the local system for systems equipped with Centralized
Attendant Service. Call Park cannot be accessed from release-link trunks.
China - Attendant Monitor
If a DN being monitored becomes parked by another party, the Attendant
Monitor feature is deactivated.
Conference
A parked call can be accessed after Conference is activated
Console Presentation Group Level Services
If the attendant who parked a call on the System Park DN is busy when
that call is recalled and the parking attendant does not belong to the same
Console Presentation Group (CPG) specified for the tenant of the calling
station, the parked call is presented to an idle attendant in the same CPG
specified for the calling station. If no attendant in that CPG is available to
receive the recall, the parked call is queued until one of the attendants
in the CPG becomes idle.
Tenant access checking between the set (A) who picks up a parked call and
the party (B) who parked the call, is enforced as follows:
•
•
•
Digital Private Signaling System 1 (DPNSS1) Executive Intrusion
Attempts to intrude into a parked call receive Executive Intrusion Denied
treatment.
Display of Calling Party Denied
When the Call Park timer expires on a parked call, a set's display reflects the
Directory Number the call is parked against. The display does not include
the name and DN of the calling party. When a parked call is retrieved by
another set, display information is based on the DPD Class of Service of
the individual sets.

If B is a set, tenant-to-tenant access must be allowed between A and B.
If B is an attendant, A and B must belong to the same CPG for
tenant-to-tenant access.
If access is denied, set A (who intends to pick up the access-denied
parked call) receives a blocking tone.
