There was a Tech-Tip on this a few years ago. The setup is very similar, however a little bit different. It requires only one button for each park and can utilize any IST from any Hub or Node on the network. This setup works better for me so I thought I'd share. Let me know if you guys find any errors in the documentation.

Parking across the Comdial Network

1. This work around will not function exactly the same as Comdial’s true Park feature, however, it will
allow users to park and retrieve calls between Hub and all Nodes throughout the entire Comdial Network.
2. This work around basically consists of transferring a call to an IST port. The retrieving party will press the shift key followed by the flashing DSS button to collect the caller.
(This will be made possible, by utilizing Station Monitoring in Class of Service programming.)
3. There are four switch requirements and considerations:
a) The first is one IST port will be used for each “Park” button. If you require the
ability to place multiple calls on “Park”, you will need to use multiple IST ports.
b) The second consideration is, if you would like to view the status of each of these
“Park” ports, the IST ports must be provisioned under the Remote Monitors. There is a
maximum of 30 network monitors per Node.
c) The third consideration is to ensure buttons are available on all phones requiring the ability to
view and access these IST “Park” ports.
d) The last consideration is to program a speed dial at the shift level of the park button to be used to retrieve the parked call.
Programming: IST ports can be supplied from any networked switch.
1. Log into the system using VMMI.
2. Click on Programming/Cabinet View and install an IST board into an available slot.
3. Click on Programming/Stations and assign extension number(s) to all IST ports to be used for the “Park” port application.
4. Click on Programming/Stations and select the first IST “Park” port.
5. Verify there are no group intercoms in the Intercom Hunt List of any of these IST ports. The reason for
this is if the IST port already has a call “parked” on it, the next caller will receive a busy signal.
6. If you wish your caller to hear “Ringback” while “parked” select “yes” to Transfer Ringback under
Programming/Lines for each of the incoming and outgoing lines on the system.
For example, a call comes into the Hub system via PRI circuit. Each PRI channel in the Hub is set to
allow Transfer Ringback. When the caller is transferred to an IST “Park” port on the Node, the
incoming caller will continue to hear ringback until they are answered either by a Node user, or recalled
back to the Hub extension.
7. Otherwise, you may select “no” to Transfer Ringback on each line, and the caller will hear what is
programmed in the Music On Hold option of the Line Attribute programming.
8. Click on Programming/Station Menu/Class of Service and select the appropriate Class of Service(s)
for all of the phones. Select “yes” for Station Monitoring.
9. Log into the Hub system using VMMI, click on Programming/Networking/Node Configuration and
add all the IST “Park” ports that the Node will need to use from the Hub and additional Nodes.
10. Button map the appropriate IST “Park” port on each phone as needed. This is mandatory Programming use to park calls and receive BLF park indication. On the same buttons, program a speed dial on the SHIFT level as:
intercom *4xxx. (*4 indicates directed pickup code and xxx indicates the IST extension number).

To Place a caller on “Park”:
1. While talking on a call, press Trns/Conf then the appropriate PARK button, and hang up.
To Retrieve a caller on “Park”:
1. Press SHIFT and the appropriate PARK button.
**NOTE: This is a “work around” and not a “global” fix. This procedure allows an extension at one
location to ultimately place a call on hold in a “park” fashion and be accessible from another location.
