OCCP requires several ports to be opened outbound to our server(s).
Depending on which server you are on, the firewall rule assumed here is
Source = You
Destination = OC Servers (Check your welcome email) except for Google STUN server
Port = Required to open
*If you do not use the webphone (OCCP) to make and receive calls (i.e you have a softphone installed or hardware phone), you do to need to configure the ports 8088 and 8089.
