Enable SSL on the UDM Pro Bridge

This is an optional step and enables the provisioning bridge to use SSL to communicate with the phones.

Requirements: 

1. A valid .pfx or .pkcs12 certificate issued by a Polycom Supported Certificate Authority. Details of the supported authorities can be found on the Latest Polycom® UC Software Release page by searching for "certificate updates" and filter on VVX or Trio depending on which you require. As well as the CA, any intermediaries need to match along with key length and algorithm.
2. Remote access to the server running the bridge. 

 Step-by-Step Guide:

1. Open the UDM Pro Bridge Configuration manager on the server.
2. Expand the Bridge Settings.
3. Change the Bridge Listening Port to 443.
   
4. Click on "Add Certificate", browse to the certificate and select it.
5. Stop and start the bridge.

The provisioning bridge should now be running on port 443 using the HTTPS protocol.
