hi, i am familiar with current internet connections and installations. a friend of mine is a teacher, and would like to install a voice-over ip system within the school. i am a little unsure as to what steps need to be taken to get going. i would imagine some kind of software will be needed on each terminal. are there any alterations that need to be made to the current broadband setup, or any legislations that need to be looked at before commencing. any advice on the subject will be much appreciated.
