If Customer Certificates are not installed in the trusted certificate store on the IP Phone, you
can use one of the following methods to manually validate an unsigned certificate
• Manual A (default)
• Manual B
Manual A
If the file containing a Customer Certificate is not signed, a prompt appears on the screen with
a fingerprint for the file as a whole, regardless of the number of certificates contained in the
file. If you confirm that the fingerprint is correct, all certificates in the file validate and save. You

Manual A uses a 20 digit (64 bit) fingerprint. You must confirm the fingerprint, which appears
on the screen. See
The screen shows the file type and a prompt to install or reject the file. After 30 seconds, the
prompt times out and the certificate is automatically rejected.
