Import Export certificates in PKCS#12
An encrypted PKCS #12 file format can now be used to import/export both the private key and the
corresponding certificate into the Codec Unit from the XT web interface. The file can be password
protected. You can import/export the certificate for TLS or for the HTTPS connection to XT Web
Server.
If an USB key is plugged, you can import and export a file also using the XT GUI menu.

Encryption Preferences
In this version, it is possible to disable audio alerts for encryption, to disable SIP proprietary
encryption (which can be used when connecting to XT Series systems where TLS is disabled or not
supported) or to configure the minimum key size accepted for Diffie-Hellman encryption. It is also
possible to specify different preferences for unprotected calls with XTD server and clients.
To change encryption preferences, browse to
[GUI] > CONFIGURE > ADVANCED> CALLS>ENCRYPTION:
[WEB] > ADMINISTRATOR SETTINGS> CALLS>ENCRYPTION:
Unprotected Calls for XTD: a different security policy can be specified for calls between XTD
server and XT. Calls between XTD clients and XTD server can be encrypted, but as XTD server
is deployed inside company’s premises the traffic between XTD server and XT is not encrypted.
You can usually accept unprotected XTD calls safely (they are encrypted between the clients and
the server). The default is “Accept, no information about the encryption status”.
