Performing an Image Upgrade and Remote Reboot
Reset each phone.
Step 4
The phone contacts the TFTP server and requests its configuration files. The phone compares the image
defined in the file to the image that it has stored in Flash memory. If the phone determines that the image
defined in the file differs from the image in Flash memory, it downloads the image defined in the
configuration file (which is stored in the root directory on the TFTP server). Once the new image has
been downloaded, the phone programs that image into Flash memory and then reboots.
Dual Booting from SCCP or MGCP to Release 4.0
Step 1
If you are dual booting from a Cisco IP phone running the SCCP protocol, open the OS79XX.TXT file
with a text editor and change the file to include P0S30202.
Step 2
If you are dual booting from a Cisco IP phone running the SIP protocol, open the OS79XX.TXT file with
a text editor and change the file to include P0M3-04-2-00.
Copy the Release 4.2 image P0M3-xx-y-zz.bin, where xx is the release major version, y is the release
Step 3
minor version, and zz is the maintenance number, from Cisco.com to the root directory of the TFTP
server.
Using a text editor, open the configuration file and update the image version specified in the
image_version variable. The version name in image_version variable should match the version name
(without the .bin extension) of the latest firmware that you downloaded (for example, P0M3-xx-y-zz).
Reset each phone.
Step 4
Performing an Image Upgrade and Remote Reboot
With Release 4.0 and later releases of the Cisco MGCP IP phone, you can perform an image upgrade
and remote reboot using Notify messages and the syncinfo.xml file.
Note
To perform an image upgrade and remote reboot, an MGCP call agent and a TFTP server must exist in
the phone network.
To upgrade the firmware image and perform a remote reboot, complete the following steps:
Using an ASCII editor, open the MGCPDefault.cnf file located in the root directory of your TFTP server
Step 1
and change the image_version parameter to the name of the latest image.
Using an ASCII editor, open the syncinfo.xml file located in the root directory of your TFTP server and
Step 2
specify values for the image version and sync parameter as follows:
<IMAGE VERSION="image_version" SYNC="sync_number"/>
