Help noob with Skype4Py in Python

[Hylle]

Hi

I have problems using Call module functions from the package Skype4Py.

Here's my code so far:

import Skype4Py
import time
skype = Skype4Py.Skype()
skype.Attach()
ring = Skype4Py.call.Call
Offer = "Echo / Sound Test Service"
ring.Finish()

Here's my error for this code:

Traceback (most recent call last):
File "C:\Users\a user name\Documents\skypecaller.py", line 7, in <module>
ring.Finish()
TypeError: unbound method Finish() must be called with Call instance as first argument (got nothing instead)

I am simply clueless about this.

Im trying to get ahold of this Call class functions.
