I want to use Skype on my pc but cannot get it to work.
My pc is behind a Cisco ASA firewall and only port open on firewall is 8080 for proxy.
Can Skype only work with proxy or must I open additional ports on ASA please advice.

According to this article...
When you install Skype, a port above 1024 is chosen at random as the port for incoming connections. You can configure Skype to use a different port for incoming connections if you wish, but if you do, you must open the alternative port manually.

This has more details configuring the Port for Skype:  Which ports need to be open to use Skype for Windows desktop?

Port 8080 is used to connect to Proxy server and not to Skype servers, hence you may need to set proxy authentication in order to enable Skype to connect to internet
Because Skype can work on standard TCP 80 and 443 ports so no need to open explicit ports on firewall. Just take care of proxy authentication to work with Skype

basically under Skype software you need to provide proxy address with port number and need to provide authentication, then hopefully it should work unless your network administrator explicitly blocked Skype traffic within firewall just like they blocks Gtalk and so on.
