I will gladly contribute back to the documentation (where I won't be more harmful than helpful) and especially contribute deployment guides if all works out.
Alright, so I have managed to get outbound partially functional at least. If I redirect an inbound PTSN call back out to the PTSN (such as forwarding the call back to my phone that I'm calling from) then I can get it to work. I'm having issues with my SIP device calling but now that I can see how to view debug info on the Kazoo core itself, I suspect I'll be able to discover more about that problem.
