This command creates a call-park slot that is a floating extension,
or ephone-dn that is not bound to a physical phone, at which phone users can
place calls on hold for later retrieval from the same phone or from another
At least one call-park slot must be defined with this command before
the Park soft key displays on IP phones in a Cisco Unified CME system.
Phone users park calls using the Park soft key. A phone user can then
retrieve a call by dialing the extension number of the call-park slot. On SCCP
phones, the phone user who parks the call can also retrieve the call by using
the PickUp soft key and an asterisk (*). Other SCCP phone users can retrieve
the call by using the PickUp soft key and dialing the extension number of the
Calls can also be transferred to a call-park slot using the Transfer
key; a transfer to a call-park slot is always a blind transfer. Calls can also
be forwarded to a call-park slot, and callers can directly dial call-park
When a call that uses a G.711 codec is parked, the caller hears the
music-on-hold (MOH) audio stream; otherwise, the caller hears the on-hold tone.
directed keyword enables the extension as a
park slot for Directed Call Park. To retrieve a call from a directed call-park
slot, you must define the retrieval prefix with the
fac command. The retrieval prefix is
supported for both SCCP and SIP phones.
reservation-group keyword allows you to
assign ownership to call-park slots by using Park Reservation Groups. A park
slot configured with a park reservation group can only be used by phones
configured with the same park reservation group. A park slot without a park
reservation group can be used by any phone not assigned to a park reservation
A reminder ring can be sent to the extension that parked the call by
timeout keyword, which sets the interval
length to wait before sending call-park reminder rings. The number of time-out
intervals and reminder rings are configured with the
limit keyword and argument. For example, a
limit of 3 timeout intervals sends 2 reminder rings (interval 1, ring 1,
interval 2, ring 2, interval 3). The
limit keywords and arguments also set the
maximum time that calls stay parked. For example, a timeout interval of 10
seconds and a limit of 5 timeout intervals (park-slot
5) will park calls for approximately 50 seconds.
timeout keyword is not used with this
command, no reminder ring is sent to the extension that parked the call. If the
timeout keyword is used, a reminder ring is
sent only to the extension that parked the call unless the
notify keyword is also used to specify an
additional extension number to receive a reminder ring. When an additional
extension number is specified using the
notify keyword, the phone user at that
extension can retrieve a call from this slot by pressing the PickUp soft key
and an asterisk (*).
Each call-park slot can hold one call at a time, so the number of
simultaneous calls that can be parked is equal to the number of slots that have
been created. The
reserved-for keyword creates a call-park slot
that is dedicated for use by one extension so that extension always has a slot
available at which to park a call. With nonreserved slots, multiple call-park
slots can be created with the same extension number so that all the calls that
are parked for a particular group can be parked at a known extension number.
For example, at a hardware store, calls for the plumbing department can be
parked at extension 101, calls for lighting can be parked at 102, and so forth.
Then, anyone in the plumbing department can pick up calls from extension 101.
When multiple calls are parked at the same extension number, they are picked up
in the order in which they were parked; that is, the call that has been parked
the longest is the first call picked up from that extension number.
IP phone users park calls at their dedicated call-park slots using
the Park soft key. Phone users can also transfer calls to dedicated call-park
slots using the Transfer soft key and a standard or custom feature access code
(FAC) for call park. On analog phones, users transfer calls to dedicated
call-park slots using hookflash and a standard or custom FAC for call park. The
standard FAC for call park is **6. Custom FACs are created using the
If a dedicated park slot is not found for an ephone-dn attempting to
park a call, Cisco Unified CME uses the standard call-park procedure; that is,
the system searches for a preferred park slot (one with an ephone-dn number
that matches the last two digits of the ephone-dn attempting to park the call)
and if none is found, uses any available call-park slot.
If a name has been specified for a call-park slot, that name is
displayed instead of an extension number on a recall or transfer of the call.
A parked call can have the following dispositions after its timeouts
- Recall—If you specify that a call should be recalled to the
parking phone after the timeout interval expires, the call is always returned
to the phone's primary extension number, regardless of which extension on the
phone did the parking.
- Transfer—If you specify a transfer target, the call is transferred
to the specified number after the timeout intervals expire instead of returning
to the primary number of the phone that did the parking.
- Alternate—You can also specify an alternate target extension to
which to transfer a parked call if the recall or transfer target is in use.
In use is defined as either ringing or connected to a call.
For example, a call is parked at the dedicated park slot for the phone with the
primary extension of 2001. After the timeouts expire, the system attempts to
recall the call to extension 2001, but that line is now connected to a
different call. The system transfers the call to the alternate target that was
specified when the park slot was defined.
- Disconnect—When a timeout limit is set and no other disposition
has been specified, a call parked at a call-park slot is disconnected after the
number of reminder timeouts are reached.
