Avaya 1230 - SRTP Support with Avaya Aura

SIP 4.4 includes a default device certificate in the firmware, allowing easy connection to Avaya Aura
through Session Manager using TLS . The IP Deskphones already have an embedded CA
certificate which is trusted by Avaya Aura
®
; the embedded device certificate eliminates the need for
customers to generate and install device certificates manually.
If used, embedded device certificate information is displayed in the IP Deskphone and in the output
of appropriate PDT commands.
The default embedded device certificates are trusted by the Avaya Aura
®
system. If Aura is
configured so that default certificates are replaced by customer certificates, then appropriate CA and
device certificates must be installed on the IP Deskphones.
Important:
The default embedded device certificates are trusted by the Avaya Aura
®
system. If Aura
®
is
configured so that the default certificates are replaced by customer certificates, then the
appropriate CA and device certificates must be installed on the IP Deskphones as well.
Configuration
To support the embedded device certificate, SIP 4.4 introduces the following parameter:
USE_DEFAULT_DEV_CERT [YES/NO]
— YES – Use the default device certificate if no customer device certificate is installed.
— NO – Do not use the default device certificate (default).
This parameter controls the use of the default device certificate for HTTPS/TLS connections. The
default value is NO. It is configured in the device configuration file.
