Mainly stretch packages (and some from ubuntu repo), but I had to rebuild some packeges with dpkg-deb changing libcurl3 to libcurl4.
Also installing libfreeswitch1 was pretty hard.
At the end (after a couple of apt --fix-broken install) I was able to install freeswitch-meta-all and, after fixing persmissions, both fs and fusionpbx works.
