... but not every STUN server is also a TURN server. In particular,
there are lots of free community-provided STUN servers out there.
telepathy-gabble defaults to (iirc) stun.telepathy.im, which is provided
by Collabora; that's sufficient to get through relatively "friendly"
NATs, but it does not offer TURN (if it did, it would cost us a lot more
bandwidth and would be a privacy concern for Telepathy users).
