Or just use an older model of skype something before the 4.1 (I say use an older version as last I checked the new skype had lost this function. There was talk of them reintroducing it which they may have done by now)
In skype right click the person in your list and create the quick dial number.
Now just dial the line setup for skype in axon and the quick dial number.
So if your skype uplink is 6 and you gave the person the number 9
You would dial 69
Have fun
