## ##
## ##
## This file is intended for upgrading 96xx telephones to ##
## SIP or H.323 version, based on the phone model. ##
## ##
## By default all 96xx models will be upgraded to the new ##
## H.323 version. The user can change the script for cases##
## other than the model default. ##
## ##
## Note that the H.323 software distribution ##
## 96xxupgrade.txt should be renamed to ##
## 96xxH323upgrade.txt and the SIP software distribution ##
## 96xxupgrade.txt should be renamed to ##
## 96xxSIPupgrade.txt. ##
## ##
## If the user replaces this file with the 96xxupgrade.txt##
## of SIP or H.323 software distribution, all 96xx phone ##
## models will be upgraded to SIP or H.323 accordingly ##
## unless the SIG parameter was configured correctly on ##
## the 96xx phones. ##
