Certificates
The phone system supports the establishment of secure data connections on the Internet with
the TLS security protocol (Transport Layer Security). With TLS, the client (the phone) uses certif-
icates to identify the server. These certificates must be stored on the base stations.
Accept all certificates
Mark the Yes radio button, if you want to accept all certificates.
Server certificates / CA certificates
The lists contain the server certificates or CA certificates that have been certified by a certifica-
tion authority (CA). The certificates in both lists have already been implemented by default or
have been downloaded via the Web configurator and are classed as valid, i.e., have been
accepted.
If one of the certificates becomes invalid, e.g., because it has expired, it is transferred to the
Invalid certificates list.
Invalid certificates
The list contains the certificates that have been received from servers but have not passed the
certificate check, and certificates from the Server certificates / CA certificates lists that have
become invalid.
Accepting / rejecting invalid certificates
Accepting a certificate:
Select the certificate and click on the Accept button . . . depending on its type, the certificate
is transferred to one of the Server certificates / CA certificates lists (even if it has already
expired). If a server responds again with this certificate, this connection is accepted immedi-
ately.
Reject a certificate:
Select the certificate and click on the Reject button . . . the certificate is transferred to the
Server certificates list with the label Rejected. If a server responds again with this certificate,
this connection is rejected immediately.
Checking information about a certificate
Select the certificate and click on the Details button. . . . a new web page appears, displaying
the properties of the certificate.
Deleting a certificate from one of the lists
Select the certificate and click on the Remove button. The certificate is deleted from the list
immediately.
