Configuring Ssl Certificates - Cisco TELEPRESENCE ISDN GATEWAYS 2.0 Online Help Manual

Configuring SSL certificates

If the ISDN gateway has the Secure management (HTTPS) or Encryption feature key installed, and
you enable the secure web service on the Network > Services page, you will be able to access the
web interface of the ISDN gateway using HTTPS. The ISDN gateway has a local certificate and
private key pre-installed and this will be used by default when you access the unit using HTTPS.
However, we recommend that you upload your own certificate and private key to ensure security as all
ISDN gateways have identical default certificates and keys.
To upload your own certificate and key, go to Network > SSL certificates, complete the fields and
click Upload certificate and key. Note that you must upload a certificate and key simultaneously.
After uploading a new certificate and key, you must restart the ISDN gateway.
If you have uploaded your own certificate and key, you can remove it later if necessary; to do this,
click Delete custom certificate and key.

Usage tips
Where the certificate has been
self-issued, these details will be the
same as for the Subject.
Your web browser uses the SSL
certificate's public key to encrypt
the data that it sends back to the
ISDN gateway. The private key is
used by the ISDN gateway to
decrypt that data. If the Private key
field shows 'Key matches
certificate' then the data is securely
encrypted in both directions.
