           Summary: Need to document how to do an ICE -> RawUdp fallback
                    for usage of ICE with SIP
           Product: Telepathy

>From #24936:

For ICE->rawudp fallback, we probably want to have an API
"ForcedRemoteCandates" or something, that will overrides the regular remote
candidates. That API should be the only one called in the case of rawudp (ie..
in rawudp mode, the ICE candidates are ignored). In the Farstream api break, I
plan to have rawudp implement only force_remote_candidates() and not
add_remote_candidates(), the second one will be only for ICE and ICE-like
protocols.

Yes, every ICE implementation needs to support rawudp fallback, otherwise its
not compliant (ie, its not ICE).

Also, don't confuse with SelectedCandidate, this is to tell other side how the
ICE negotiation has concluded (it prevents a race in the ICE negotiation). So
its unrelated to rawudp fallback.
