Port blocking is a thing of the past. Nowadays Next Generation Firewalls are used, which block traffic at the application layer and not at the network layer. FaceTime uses port 443 mainly, just like any other HTTPS application.
The Next Generation firewalls will detect the applications sending/receiving traffic through port 443 and will allow the Administrators to block specific applications.
