Configure Encryption Settings for SVC Calls
You must complete two quick tasks to enable encryption for SVC calls:
● Set the transport protocol.
● Set AES encryption.
To set the transport protocol:
1 In the web interface, go to Admin Settings > Network > IP Network.
2 Click SIP to expand the section.
3 In the Transport Protocol list, select TLS.
4 Click Save.
To set AES encryption:
1 In the web interface, go to Admin Settings > Security > Global Security.
2 Click Encryption to expand the section.
3 In the Require AES Encryption for Calls list, select When Available, Required for Video Calls
Only, or Required for All Calls.
4 Click Save.
For more information on SVC-based calling, refer to Set SVC Call Preferences.
Setting Description
Require AES Encryption for
Calls
Specifies how to encrypt calls with other sites that support AES encryption.
•Off—AES encryption is disabled.
• When Available—AES encryption is used in calls with systems that
support it. Calls without encryption are allowed when connecting to
systems that don't support it. For multipoint calls, this means that some
systems might be connected with AES encryption while others are
connected without it.
• Required for Video Calls Only—AES encryption is used in all video calls.
Calls with systems that do not support it are disconnected. Audio calls
using an attached SoundStation IP 7000 are allowed to connect.
• Required for All Calls—AES encryption is used in all calls. Calls with
systems that do not support it are disconnected. Audio calls using an
attached SoundStation IP 7000 are not allowed to connect, since these
calls are not encrypted.
Require FIPS 140 Cryptography
(web interface only)
Enables the exclusive use of the FIPS 140-2-validated software cryptography
module for cryptographic functions. Also disables all “weak” protocols and
ciphers, including:
• SSLv2
• SSLv3
• Non-FIPS 140-2 approved TLS cipher suites
