Delete CUCM trust lists
Sign in to the web interface and navigate to
Security >
CUCM Certificates
.
Delete the CUCM trust lists
Click
Delete CTL/ITL
to remove the trust lists.
As a general rule, you should not delete old CTL
(Certificate Trust List) and ITL (Initial Trust List) files.
In these cases, you must still delete them:
• When you change the CUCM IP address.
• When you move the endpoint between CUCM
clusters.
• When you need to re-generate or change the CUCM
certificate.
Overview of trust list fingerprints and certificates
The trust lists’ fingerprints and an overview of the certificates in
the lists are displayed on the web page.
This information may be useful for troubleshooting.
