ONFIGURATION
To change the IP settings of a telephone:
1 Click Telephone Configuration > Telephones.
If you are updating the IP Settings of a different type of device (such as an
Attendant Console or a Digital Line Card), click the appropriate tab.
2 Click the extension of the telephone that you want to update.
3 Click the IP Settings tab.
4 Type the new values for IP Address, Subnet Mask, and Default Gateway
address in the fields.
5 Click OK .
6 Disconnect the device from the Call Processor subnetwork.
7 Connect the device to the new subnetwork as follows:
■
Connect a telephone or a single-port ATA to a port on either a switch
or hub that is connected to the new subnetwork.
■
Plug a card into a chassis that is connected to the new subnetwork.
8 Reboot the device:
■
Remove power from a telephone or a single-port ATA, and then
reconnect it.
If the device is a card, it reboots automatically when you insert it into
the new chassis. You do not need to remove power to the chassis
when you add or remove cards.
When you change IP Settings, the system terminates all current calls
through this device.
9 In the NBX NetSet utility, return to the IP Settings window for the device.
10 Verify that the device now reports the IP settings that you entered.
CAUTION: If you configure an 3Com telephone for operation on a
subnetwork other than the Call Processor’s subnetwork, and if you access
the
IP Settings window to verify that the device settings are correct, click
Cancel to exit the window. If you click OK , the system applies the IP
settings in the Manually Assigned IP Settings fields. By default, all these
fields contain 0.0.0.0. If you click OK , all the IP settings for the telephone
are set to 0.0.0.0, and the telephone no longer works on the remote
subnetwork.
