Hello Karel!

What if I need to exchange sometimes something with people who are
still pure PSTN connected?
a) Let the POTS user dial in to an internet gateway and he could use IP to connect you.
b) Ask a node with POTS and IP to establish a direct route between those people and you and use that node as a gateway.
c) Get old hardware and a real modem. Even if you need an POTS/VOIP ATA converter it will be cheaper than the 100.000 for kickstarter project or your 100 share for the kickstarter. You will get the fun for finding the right Init-AT command for free.
d) Get old hardware, a real modem and your own POTS provider. No fun because Init ATZ.
e) Send encrypted mircoSD cards via snailmail.
f) Send a carrier pigeon.
Did i forget anything? Hm, yes but that's an option i don't like.
g) disconnect those people.
Because the initial question wasn't FTN related i would prefer option a.
h) establish an inmarsat link with those people.

Kai
