Re: Local Calls?
When I worked for the Big Broadcasting Concern in London, we were allowed to make local personal calls free. We had a national "internal" engineering exchange system, so it was a fairly simple hack to interconnect the EMX to the office PBX phone system in each building around the country. It was then just a question of using the "special" extension in each building to route calls around the country!
Anon 'cos it was a bit naughty!
