You can configure the DES server to notify the phone that it needs an identity certificate for mutual
authentication with the provisioning server. The phone requests the certificate and then inquires
the DES server for the provisioning server URL.
To use this functionality, you must install the Avaya Devices root certificate for issuing identity
certificates on the provisioning server.
Disabling DES
During the first boot-up, the administrator can disable the DES discovery in either of the following
ways:
• by setting DES_STAT as 0 or 1 in DHCP option 242
• by setting DES_STAT as 0 or 1 in the
46xxsettings.txt
file
• by disabling
DES Discovery
in the phone web interface (
Management
