Security
For extra security, you may wish to have the
VCS communicate with other systems (e.g.
servers such as LDAP servers, neighbor VCSs,
or clients such as SIP endpoints) using TLS
encryption.
For this to work successfully in a connection
between a client and server:
the server must have a certificate installed
•
that verifies its identity. This certificate
must be signed by a Certificate Authority
(CA).
the client must trust the CA that signed the
•
certificate used by the server.
The VCS allows you to install appropriate files
so that it can act as either a client or a server
in connections using TLS.
For an endpoint to VCS connection, the
VCS will be the TLS server. For a VCS
to LDAP server connection, the VCS will
be a client. For a VCS to VCS connection either
VCS may be the client with the other VCS being
the TLS server.
Select the file containing...
Allows you to upload a PEM file that identifies
the list of Certificate Authorities trusted by
the VCS. The VCS will only accept certificates
signed by a CA on this list. If you are
connecting to an LDAP database using TLS
encryption, the certificate used by the LDAP
database must be signed by a CA on this list.
Upload CA certificate
Click here once you have selected the file to
upload it.
Select the server private key file
Allows you to upload a PEM file that identifies
the private key used to encrypt the server
certificate used by the VCS. This private key
must not be password protected.
Select the server certificate file
Allows you to upload a PEM file that
contains the server certificate used for
HTTPS connections to the VCS from user
or administrator web browsers, and by SIP
endpoints or servers connecting to the VCS
over TLS.
Show server certificate
Shows you the currently uploaded PEM file containing the certificate used by the VCS to identify
itself to SIP and HTTPS clients when communicating over SSL/TLS.
Overview
To enable security using the web interface:

.
You will be taken to the
Security
page.
Upload server certificate data
Click here once you have selected both the
private key and certificate files to upload them.
Enabling Security
Show CA certificate
Shows you the currently uploaded PEM file
that identifies the list of Certificate Authorities
trusted by the VCS.
The files that enable secure
connections over TLS are installed via
the web interface. They cannot be
installed using the CLI.
