Asterisk 14 with opus is already available for those who are testing SNG7. Simply run ‘yum update’ and then ‘asterisk-version-switch’ and you’ll be able to switch to Asterisk 14.
However, I’m going to be releasing a new ISO (beta2) very soon now (in the next couple of days) with some pretty important fixes, so if you’re not ALREADY running it, don’t bother 8)
Edit: Opus will not be available on 6-based Distros in the immediate future, because of technical issues when compiling.
