Security
For information about toll fraud, see the respective call server documents on the
Avaya Support
website. The 9600 Series IP Deskphones cannot guarantee resistance to all Denial of Service
(DoS) attacks. However, checks and protections are in-built to resist such attacks while
maintaining appropriate service to legitimate users.
All 9600 Series IP Deskphones that have WML Web applications support Transport Layer Security
(TLS). The deskphone uses TLS to establish a secure connection to a HTTP server, in which the
upgrade and settings file can reside. The 9600 Series IP Deskphones support TLS 1.2 cipher
suites. You can configure the TLS_VERSION parameter to use either TLS 1.2 only, or use older
TLS versions as well.
The following list of applications and processes use TLS 1.2:
• WML browser using HTTPS
• H.323 signaling over TLS
• SLA mon agent
• IPSec VPN with certificate based authentication
• 802.1x EAP-TLS
• Single Sign On (SSON)
• Configuration files download using HTTPS
• Backup/restore using HTTPS
• Debug report generation using HTTPS
• OCSP over HTTPS
