Starting with openUC and sipXecs 4.6.0 Update 3 HTTPS provisioning is possible with Polycom phones running firmware 4.0 and later.
Overview
In order for the phone and sipXecs to communicate securely, a certificate must be used. We distinguish two cases:
- using self signed certificate - we'll discuss about using sipXecs default self signed certificate
- using a certificate signed by a well known certificate authority.
In order to setup a phone to provision using HTTPS you must select Server Type: HTTPS under Admin Settings > Network > Provisioning Server.
