So after much searching on the interwebs I have come up with a working config for configuring Skype connect in the FreePbx GUI of asterisk PBX. There are four things you need to have from skype to set up your trunk. They are your SIP User ID, Password, Skype Connect Address, and the UDP port. You can find them at the Skype manager page by clicking on “View profile” on the skype connect page and then clicking on Authentication details. Below is an example of the Authentication details page.
