Section 13 Ip Station (Sip Multiline Telephone) - NEC Sl2100 Networking Manual

ISSUE 1.0
The IP Phone downloads the firmware from the FTP/TFTP server and reboots when the download is
complete.
12.2 Checking the Firmware Version
To check the IP Phone firmware version:
1. Press and hold the HELP button on the IP Phone.
2. Press 2 (System Information).
3. Press 5 (Keyset Information).
4. Press the Next softkey two times.
12.3 Upgrading Automatically
This procedure causes all IP Phones to attempt firmware upgrade the next time they connect to the
CPU. This can make the upgrade procedure easier, as it is not necessary to visit every telephone to
perform the upgrade.
This can cause problems if, for example, a PoE (Power over Internet) switch is used. When the PoE
switch is powered up, all telephones connect to the FTP/TFTP server at the same time. This causes a
large amount of data for the FTP/TFTP server to transfer over the data network.
To avoid this, connect the telephones to the PoE switch gradually, to allow time for each telephone to
upgrade before connecting the next.
To enable automatic upgrade:
1. Install and configure an FTP/TFTP server.
2. Copy the firmware file itlisipr.tgz to the default FTP/TFTP directory.
3. Set the server mode to FTP/TFTP in Program 84-07-01 and specify the IP address of the FTP/
TFTP server (this is the PC where the FTP/TFTP software is installed) in Program 84-07-02.
4. In Program 84-28 program the Firmware Directory path on the FTP/TFTP server and assign the
file name (itlisipr.tgz).
5. In Program 90-42, assign the software and hardware versions. An example of the hardware
assignment would be 09.01.03.06, this is Hardware Version 9.1.3.6.
S 13 IP STATION (SIP MULTILINE TELEPHONE)
ECTION
13.1 Description
The NEC SL2100 system supports IP phones using Session Initiation Protocol (SIP). These IP
telephones have the same look and functionality as typical multiline telephones, but they are
connected to an VoIPDB card in the CPU rather than hardwired to a Digital Station port.
Some of the benefits of an IP phone over a traditional TDM phone are described in the following list:
• Reduced telephone re-location costs. Unplug an IP telephone at one location and plug it into
another VoIP ready jack at another location. The extension number can stay with the telephone, if
programmed to do so.
• Multiple users can share the same IP telephone but keep their own personal extensions. With an IP
phone you have the ability to log the phone out, then log back in with another extension number. All
of your personal settings follow the login ID of your extension.
