a few words on current state of #voice
I should notice, that there is even technical possibility to run free GSM nodes. Didn't check if #software
well support 3G, which became a minimum for systems that I use. This project found its way only in rural areas, where people have to provide their communications by themselves. I believe such usage was intention of developers. On the other hand, mesh networking projects are around urban areas for 7 years at least, and still no luck.
