UPGRADING IN IP OFFICE
Avaya B179 supports the IP Ofce check-sync message with le id 4 for rmware
upgrades. Please see the IP Ofce documentation for more information.
HOW TO DO A DOWNGRADE
The only way to “downgrade” – install a previous version of the rmware - is to restore the
rmware to factory default (page 39) and then install the preferred rmware.
