atcomsystems.ca/forum Forums General General Telephone & Systems Information Volunteer opp's?

When I was a kid, my dad worked for AT&T as a pbx tech. There was a group of 'old' guys that would take old 1A2 Key systems, etc, and kinda refurb them, then take them to places like Africa and South America and install them in poor hospitals as basically whole building intercom systems, if that makes sense. Now fast forward to today. My dad passed last year, I'm a pbx guy now, after having worked at Lucent and Avaya. I'm trying to find out if there are any volunteer opportunities for 'phone guys'? Does anyone know of such things? I don't mind where it's at.
