assigned port number when the telephone is connected. The MAC address is printed on the barcode
label on the bottom of the telephone. It is a 12-digit alphanumeric number, ranging from 0~9 and A~F.
To delete a telephone registration:
Enter Program 90-23-01, and enter the extension number of the IP Phone. If connected to the SL2100
via Telephone Programming, enter a 1 to delete the IP phone and then press Hold. If connected to the
SL2100 via Web Pro, place a check next to the extension and click Apply.
S 11 SYSTEM IP PHONES AND ANALOG TRUNKS
ECTION
Due to the nature of analog-to-digital conversion, considerable echo may be encountered when using
Analog Trunks with IP Phones.
Due to all Analog trunks being different, padding of the Analog Trunks in PRG 81-07 and 14-01 may
be necessary. Even after the pad changes are made, echo may still be present the first few seconds of
the call while the echo cancellers are learning the characteristics of the circuit on this call.
It is recommended to use digital trunks when using IP phones for best performance.
Digital (ISDN, T-1, and SIP) trunks do not suffer from this problem.
When analog trunks are installed in an SL2100, PRG 90-68 (Side Tone Auto Setup) must be used.
This program will automatically change the setting of 81-07 after multiple tests are performed on the
analog line. During these tests the system will not be usable, and the system must be reset once the
test are finished.
Anytime new analog trunks are added to the system, PRG 90-68 MUST be used.
S 12 FIRMWARE UPGRADE PROCEDURE
ECTION
A new version of NEC firmware for the IP Phones can be applied automatically or manually.
The upgrade requires using an FTP/TFTP server. This is a software package that runs on a PC.
(These can be downloaded from the Internet, usually as freeware or shareware.)
12.1 Manually Upgrading Firmware
Manually upgrading the firmware uses an FTP/TFTP server, but requires the engineer visit each IP
Phone individually. This may take longer, but is more controlled as the downloads can be staggered to
avoid excessive bandwidth utilization.
To manually upgrade the firmware:
1. Install and configure an FTP/TFTP server.
2. Copy the firmware file itlisipr.tgz to the default FTP/TFTP directory.
3. To enter Programming Mode, press the Hold, Transfer, *, # button on the IP Phone.
4. To enter Maintenance Mode, press 3: Maintenance Settings.
5. To access the Download menu, press 1.
6. Enter the FTP/TFTP server IP address in Option 2 - Download Address.
7. To enter the protocol, press #3 (Protocol FTP or TFTP).
8. To select download by file, press option 1 (Download File).
9. To boot the program, press 2 (Boot & Program).
10. Press the softkey.
