VoIP solves Old world business problem

A news item hit my desk today where a IP-PBX (or softswitch) application solved a different kind of problem. Unified communications? Unified Administration? One network? Sure they get those things, but it was really just a matter of getting communication into places where TDM didn't work. I'll post the link here. Pretty cool application.
Tadiran's VoIP technology has been the perfect solution to resolve communication problems that have plagued the mining industry for years.
