i2004 Internet Telephone firmware requirements

Firmware Upgrade from a new ITG Line 2.0 card

Firmware Upgrade of an ITG Line 2.0 card

553-3001-204 Preliminary 0.10 August 2000
The i2004 Internet Telephone has field upgradable firmware. A copy of this
firmware is stored on each ITG Line 2.0 card in the system to automatically
upgrade i2004 sets if an upgrade is required. All i2004 Internet Telephones in
a system must use the same version of firmware as the ITG line 2.0 card.
When the ITG Line 2.0 card is received from the factory, it has the latest
i2004 firmware already installed in the /C:/FW directory. As each i2004
Internet Telephone comes on-line, its firmware version is automatically
compared to the version that is stored on the ITG Line 2.0 card. If they are
different, a process is started which downloads the new firmware from the
ITG line card to the i2004 Internet Telephones. After the new firmware has
been downloaded, the i2004 reboots and registers again with the ITG Line 2.0
card.
It is possible to upgrade the i2004 Internet Telephone firmware in the field.
The first step is to upgrade the ITG line cards with the latest firmware version.
This is accomplished by downloading the firmware directly from the
Meridian 1 Electronic Software Documentation (ESD) website to each ITG
line 2.0 card in the system. Refer to Procedure 23, "Upgrade i2004 Internet
Telephone firmware" on page 156 for step-by-step instructions.
Make note of the following caveats:
• The i2004 Internet Telephone is shipped from the factory with sufficient
firmware to complete the initial download.
• The firmware is downloaded to the i2004 set if it is different, which
means that it is possible to download an older version of the firmware.
• The i2004 Internet Telephone uses trivial file transfer protocol (TFTP) to
transfer the firmware, therefore the customer's network must support
TFTP. For example, the customer's network cannot be blocked by a
firewall.
