IP Phone commands 47

Configure the gateway channels and IP Phones associated with the new

node to use separate zones from the original node, if the two nodes are

on separate TLANs with no routing capability in between (see “Calls to IP

Phones in other VGMC nodes with separate TLANs” (page 43)).

IP Phone commands

This section describes IP Phone commands.

Maintenance telephone

A digital telephone functions as a maintenance telephone when you

define the class of service as MTA (maintenance telephone allowed) in

the Multi-line Telephone Administration program (LD 11). You can use a

maintenance telephone to send commands to the system, but you can use

only a subset of the commands you can enter from a system terminal.

To access the system by using the maintenance telephone, enter a SPRE

code (defined in the customer data block) followed by 91. Then enter the

overlay commands. To enter commands, press the keys that correspond

to the letters and numbers of the command (for example, to enter LD

42 Return, press 53#42##). The following overlays are accessible from

an IP Phone that operates as a maintenance telephone: LDs 30, 32,33,

34(except for TDS commands), 35, 36, 37, 38, 41, 42, 43, 45, 46 (except

TONE commands), 60, 61, and 62.

VGMC node TN password functionality

Basic craftsperson node-level TN entry password protection exists on the

IP Phones to control registration with a virtual line TN on the Call Server.

When the password is configured and enabled, instead of the IP Phone

displaying node ID and TN fields, the screen shows the four-digit node

ID and a password prompt. After you enter the node ID and password

and press OK, if the password passes the Connect Server authentication,

a screen appears with the TN field. If you do not enter the node ID and

password are not entered, the registration continues after 5 seconds and

the TN never appears.

If you enter an invalid node ID password is entered, the node ID and

password screen reappears. This screen reappears a maximum of two

times, to provide three opportunities to enter the password. After three

attempts, registration continues as if no entry occurred at the IP Phone.

You can reboot the IP Phone and try again, if necessary.

If you enter a zero length password, then the node ID, TN and password

screens do not appear on the IP Phone during registration. This provides

maximum security to prevent any entry of a password or TN from the IP

Phone.
