We explicitly permit Skype as a useful communication and business
tool for our students; however with a default deny firewall we are in
recent months  seeing some issues with call quality as most of our
Skype-Skype traffic will depend upon other Skype clients to relay
traffic - we suspect that there are a decreasing number of Skype
clients on the internet with spare CPU cycles or bandwidth to relay
those calls, but our investigations are still ongoing.

We opened a specific inbound port for Skype, and instruct all our users
to configure their Skype clients to listen on this port. Pick a random
one in the high range, like 61234, for example. This gets advertised as
part of the contact status conversation with one's friends in the network.
