I will be upgrading to 4.2 from 4.1.3 with the latest device pack. My question is if during the upgrade process 4.2 has older firmware bundled with it will it overwrite it's older firmware with my newer firmware in device pack 43. Will it change phone loads on the device defaults page?
If you use configuration files, the OS79XX.TXT file no longer controls the image used by the phone. Image version and upgrading is done through the image_version configuration parameter in the configuration files. In the startup, each SIP IP phone attempts to download the SIPDefault.cnf configuration file. This file contains the image_version parameter that tells the phone which image to run. Therefore, if you attempt to load the SIP version 7.1 software, SIPDefault.cnf must contain image_version: P0S3-07-1-00. If the image load differs from the one that is currently loaded on the phone, the phone contacts the TFTP server to convert to the new image.
