Do Not Disturb
Calls can be parked on telephone DNs that are in the Do Not Disturb mode
(DND). Telephones in the DND mode can park a call or access a parked
call. Recall of a parked call to a DND telephone is recalled to the attendant.
Generic XFCOT Software Support
Call Park feature allows an attendant or telephone user to place a call in
parked state (connected to a parked DN) where it can be retrieved by
any attendant console or station set. If the call is not retrieved after a
customer-defined time, the call is recalled to the telephone user who parked
it.
Call Park is allowed on disconnect-supervised or unsupervised IPE
loopstart Central Office trunks. If a caller on an unsupervised loopstart
trunk disconnects while the call is in parked state is detected when the
parked call is recalled or answered.
Caller disconnection during park state is detected by a disconnect
supervised loopstart trunk on an XFCOT card. The disconnected caller is
then dropped from the parked DN.
Group Call
Call Park cannot be applied on a Group Call.
Held Call Clearing
A call put on hold during a Call Park is not cleared by an on-hook action
on that set.
Hot Line
Analog (500/2500 type) Hot Line telephones with EHTA and XFA Class of
Service are allowed to park calls using the established Call Park procedures.
Once a call is parked on an analog (500/2500 type) Hot Line telephone
and the telephone is placed on hook, it cannot be unparked. Parked calls
will recall to the parking telephone after the Call Park timeout. Two-way
Meridian 1 proprietary telephone Hot Line stations that are equipped with a
Call Park key/lamp pair are allowed to park calls in the normal fashion. As
with analog (500/2500 type) telephones, a call parked from a Hot Line key
cannot be picked up using the same key.
In-Band Automatic Number Identification
If an agent parks an In-Band ANI call and it times out and recalls the agent,
the ANI number is not displayed.
INIT ACD Queue Call Restore
Parked calls are restored by ACDR as new incoming calls to the ACD DN.
