Chapter 9 Device Pool Configuration
Device Pool Configuration Settings
SRST Reference From the drop-down list box, choose a survivable remote site telephony
(SRST) reference to assign to devices in this device pool. Choose from
the following options:
• Disable—If you choose this option, devices in this device pool will
not have SRST reference gateways that are available to them.
• Use Default Gateway—If you choose this option, devices in this
device pool use the default gateway for SRST.
• Existing SRST references—If you choose an SRST reference
from the drop-down list, devices in this device pool will use this
SRST reference gateway.
Connection Monitor
Duration
This setting defines the time that the IP phone monitors its connection
to Cisco Unified Communications Manager before it unregisters from
SRST and reregisters to Cisco Unified Communications Manager.
The default value, which specifies 120 seconds, resides in the
Connection Monitor Duration enterprise parameter.
Change this setting if you need to disable the connection monitor (by
changing the value to zero) or if you want to extend the connection
monitor time.
Note When you change the value of the connection monitor duration,
it applies only to the device pool that is being updated. All other
device pools use the value in their own connection monitor
duration fields or use the value that is configured in the
enterprise parameter.
For more information, refer to the “Survivable Remote Site Telephony
References” section in the Cisco Unified Communications Manager
System Guide.
Single Button Barge This setting determines whether the devices or phone users in this
device pool have single-button access for barge and cBarge. From the
drop-down list box, choose from the following options:
• Off—If you choose this option, the devices in this device pool will
have the Single Button Barge/cBarge feature disabled.
• Barge—If you choose this option, the devices in this device pool
will have the Single Button Barge feature enabled.
• CBarge—If you choose this option, the devices in this device pool
will have the Single Button cBarge feature enabled.
• Default—If you choose this option, the devices in this device pool
will use the service parameter setting for the Single Button
Barge/cBarge feature.
