Network Group Diagnostics
The Network Group Diagnostics feature allows you to verify that Network Groups have been
programmed correctly. When the Network Group Diagnostics feature code is entered, the
platform initiates pings from each system-connected device and determines if the other devices
respond. If a device does not respond to the ping or if a firewall is detected, the system issues
a Message Print message. For more information about Message Print, refer to the Message
Print Diagnostics Manual, part number 550.8018.
The Network Group Diagnostics feature works on proprietary IP devices for the local node only.
It does not work across nodes.

Running Network Group Diagnostics

WARNING:System Performance. Because this feature affects system performance, run the diagnostics
program after normal business hours when the system is idle.

When the diagnostics are complete, the phone displays one of the following messages:
NET GROUP CHECK COMPLETED: Indicates that all IP devices within the Network
Groups are capable of communicating using peer-to-peer audio.
NET GROUP CHECK ERRORS FOUND: Indicates that either some of the IP devices are
offline or there are NATs/firewalls located between the devices. Check Message Print
to determine which errors occurred.

Seizing a Device

For troubleshooting purposes, you can enable diagnostics mode and then seize a specific trunk
or extension by entering the module, circuit, and device number.

outgoing access permission for the trunk to seize it. Toll restriction is applied to any calls placed
after the trunk is seized.
