Certiﬁcates on redeployed IP Phones

You can redeploy an IP Phone to new location, which does not use the

customer certificates already installed on the phone. Restore factory

defaults to remove all the service provider certificates. The original Service

Provider certificates and Certificate Revocation List (CRL) are removed

from the phone when you restore the factory defaults on the IP Phone.

Otherwise, you can prevent installation of any configuration files on the

phone. For example, if Service Provider certificates are on the phone and

the default Security Policy is in use, then you must restore the factory

defaults on the IP Phone before you can install new certificates.
