The opus codec was used as an external patch. It looked ugly and thus a
separate package was preffered.
Its version number is not directly related to Asterisk. It has
originally been split from the Debian packaging of Asterisk, and
starting from the same version number allowed easier upgrading. There is
no version number for the upstream code (the patch).

Technically Asterisk codecs translate to/from (typically) linear and
Asterisk combines codecs to do whatever transcoding needed. So the codec
does not transcode directly to G.711. But Asterisk can transcode between
opus and G.711.

Should work just the same.
