A user in the VOIP Users Conference Google+ chat asked for us to check which
Software supported the Opus Codec. I notice that linphone does not, but I
also noticed on the Speex website (http://www.speex.org/) that is says "—The
Speex codec has been obsoleted by Opus <http://opus-codec.org/>. It will
continue to be available, but since Opus is better than Speex in all
aspects, users are encouraged to switch—". So I was wondering what the odds
are that we might see Opus in the future in the Codec list. (granted I am
using a 3.5.2 version of Linphone from the Ubuntu repository)
