Firmware Content and Update Information
The SIP Firmware for IP Phone 1120E and 1140E supports remote firmware changes and
updates through both a manual and automated process using the TFTP, HTTP or FTP
protocol. Updates, including firmware, language files, and configuration files, may be
obtained when the phone is powered up, at specific times pre-configured by the system
administrator, or at any time upon manual request of the user. Firmware updates are done
via the SIP Firmware update/provisioning mechanism.
Customers will need to make arrangements for the TFTP/FTP/HTTP servers. A trial copy of
Windows or Linux version of TFTP server application can be obtained from several leading
vendors such as

. The SIP
Firmware Release update process involves below steps.
1) Existing SIP Firmware for the IP Phone 1120E/1140E can be updated to SIP Firmware Release 1.1
(06A4C39d29/06A5C39d29 version). The IP Phone 1120E or 1140E may be shipped with SIP version of the
Firmware that may not be the current release. Updating the SIP firmware will require a TFTP server.
2) To upgrade existing UNIStim Firmware for the IP Phone 1120E/1140E, first update the IP Phone1120E/1140E to
minimum required UNIStim Firmware version 0624C1B/0625C1B. The IP Phone 1120E or 1140E may be shipped
with default UNIStim version lower than the minimum required version.
3) Once the IP Phone 1120E/1140E is at 0624C1B/0625C1B version, the IP Phone can be updated to SIP Firmware
Release 06A4C39d29/06A5C39d29 version. UNIStim Firmware supports the TFTP or UFTP protocols. Updating
UNIStim firmware and switching from UNIStim firmware to SIP Firmware will require a TFTP server (UFTP is not
supported).
IMPORTANT NOTE: The SIP Firmware Release for IP Phone 1120E and 1140E is a migration to the SIP
protocol for these IP Phones. Loading the SIP Firmware will overwrite the existing firmware such as
UNIStim (i.e., note that it will not be possible to run both the SIP and UNIStim Firmware concurrently).
