IP Line Description, Installation and Maintenance
5Once a firmware file is found and stored in the card’s RAM drive, the
upgrade manager parses the file and updates its policy based on the
firmware version it received from file.
6The IP Phones are checked against the upgrade policy at the time they
register. If a firmware update is required, the firmware is downloaded
from the Signaling Server or the Voice Gateway Media Card’s TFTP
server to the IP Phone.
The firmware file for the Phase0/1 IP Phone 2004 is saved as X00.fw, as
X01.fw for the Phase I IP Phone 2002, and as X02.fw for the Phase II IP
Phone 2001, IP Phone 2002, IP Phone 2004, IP Phone 2007, and IP Audio
Conference Phone 2033. These filenames are required for the upgrade
manager to find certain files in either the stand-alone file server or the Master
card’s RAM drive.
In order for all Voice Gateway Media Cards to obtain the same firmware files,
ensure that the configured file server is running before any of the Voice
Gateway Media Cards boot up.
In CS 1000 systems, the Signaling Server acts as the file server and the
Master function is on the Signaling Server. As a result, no time to download
the firmware files from the file server is needed.
The /A: drive (the PC Card slot on the card’s faceplate) of the Voice Gateway
Media Card can also be used with a PC Card containing the firmware files;
the Voice Gateway Media Card is specified as the server and the file directory
specifies the /A: drive.

Graceful Disable

The DISI command in LD 32 can be used to disable the Voice Gateway
Media Card’s gateway channels when they become idle. This command
removes gateway call traffic from a Voice Gateway Media Card; however, it
does not remove the IP Phones registered to the Voice Gateway Media Card.
Even after the gateway channels are disabled, all IP Phones registered to the
card are impacted when the card is unplugged or reset. Also, if a Voice
Gateway Media Card or Signaling Server is the node Master when it is
removed, the IP Phone registration service is interrupted until the next
election occurs.
