Deleting XT Series Certificates
About this task
This section explains how to remove or uninstall a certificate from the XT Series using the web
interface.
You might need to remove certificates if:
• For privacy reasons, you do not want to keep your certificates on a shared endpoint.
• The system generated errors while creating the CSR and you want to replace it with a new
one.
• You want to use a different CA for signing your certificates.
• Your certificate has expired.
• You changed the system's IP or DNS address.
Important:
To generate a certificate signing request, you can use the system IP address or DNS
name. If you use an IP address, please assure that it is a static IP address, since the
system generates the certificate request using its IP address as the Common Name
(CN).
This procedure removes the current certificate by replacing it with a blank form. To back up a
certificate before deleting it from the system, see Backing Up and Restoring XT Series
Certificates on page 246.
Procedure
1. Access the XT Series web interface, as described in
Accessing Web Interface on
page 147.
2. Select Administrator Settings > Utilities > Certificates.
3. Leave all fields blank and select Create to start a new CSR procedure. This erases the
previous certificates.
• To generate a TLS certificate to secure SIP calls: From the XT Series web interface,
select Administrator Settings > Utilities > Certificates > TLS.
• To generate a HTTPS certificate: From the XT Series web interface, select
Administrator Settings > Utilities > Certificates > Web.
