Install the Firewall client and create an "all open" rule.

HTH,

I don't want to install firewall client coz they have thier core servers in different DMZ segment on the CISCO pix firewall which can't be accessed if firewall client is installed.
So plz tell me which ports to open for skype & how to open the ports?

allow 'All Outbound Traffic' in an access rule.

Perhaps this is your issue?
