4. MAC address
Enter the MAC address of the remote phone. The MAC address of the phone appears on the second
line of the display when the phone is powered up.
Important: DON’T connect a new Remote IP Feature Phone to the IP PBX network before
completing extension programming.
The MAC address is a 12-character alphanumeric address, of which the first six digits will always
match (00 30 4D). Enter the complete 12-character alphanumeric address. Use the following keys
to enter alphabetic characters:

5. Gateway address
Enter the address of the remote phone’s default gateway – that is, the LAN interface of the
gateway device at the remote site. The phone must be on the same subnet as the LAN interface of
the remote gateway.
6. UDP port
Enter the first two digits of the remote phone’s UDP port. This number is the base prefix UDP port.
The default UDP base is 59. The last three digits will be the station’s extension number (between
100 and 195), and will be populated by default. Extension 101, for example would have a UDP port
of 59101 by default.
The UDP port for the remote phone does not have to be the same as for the IP PBX (as programmed
in Function 81). The UDP port for the remote phone must be one that the remote gateway can
program as “open” and must not be already assigned to another device at the remote site. The
remote gateway will then have to be programmed to recognize that traffic destined for that UDP
port should be allowed to pass through its security system.
If the remote gateway cannot open UDP port 59xxx (where xxx is the phone’s extension), or if that
port is already open but designated for another device, the installer can choose any other base
UDP number between 10 and 65, inclusive. After entering the first two digits, the phone’s exten-
sion will populate the last three digits.
