This information is configured in the OTM 2.2 IP Line 4.5 application. If
using OTM 2.2, this information is configured in the File Server tab of the
Node properties. See Figure 159 on page 492.
The IP Phones use UNIStim File Transfer Protocol (UFTP) to transfer the
firmware; therefore, if the customer’s network has a firewall, port 5105 must
be explicitly opened in the firewall to enable IP Phone firmware downloads
to take place. For more information, refer to “Firmware download using
UNIStim FTP” on page 150.

IP Phone firmware upgrade from a new

Voice Gateway Media Card
Meridian 1
When the Voice Gateway Media Card is received from the factory, the
IP Line 4.5 software is located on the CompactFlash card. Go to the Nortel
web site and download the firmware for the IP Phones to the Leader card. See
Appendix F on page 903.
IMPORTANT!
All IP Phones in a system must use the same version of firmware as is
on the Voice Gateway Media Card(s).The same version of firmware for a
specific IP Phone type must reside on all Voice Gateway Media Cards in
a system. If retrieved from an external server, ensure all Voice Gateway
Media Cards retrieve the same firmware files
CAUTION
The OTM PC should not be used as the file server for the
firmware download.
