Ultrawideband Opus for Asterisk and D50, D60 line of phones?

As I understand it, Opus codec can deliver sampling rates from 8 kHz (narrowband) to 48 kHz (fullband).
Does Asterisk also support Opus ultrawideband 32kHz or even fullband 48kHz?

Also, are there any plans to add opus ultrawideband to Digiums D50, D60 line of phones?

That’s a commercial question you should ask of DIgium, not the community. Most companies would not answer such questions unless the feature was well into beta testing.

I would guess that the answer would depend on whether they seem their product being aimed at CEO level users, as this sort of thing is a CEO perk, not something needed for efficient running of businesses.

Does Asterisk 13 or 14 also support Opus ultrawideband 32kHz or even fullband 48kHz?

codec_opus for Asterisk supports the full range of opus sampling rates.

The D40, D45, D50 and D70 model phones will not support Opus. The D60, D62 and D65 model phones support a narrow-band 8kHz and a wide-band 16kHz Opus. They do not support an ultra-wideband nor a full-band variant of Opus. The D60, D62 and D65 models do support the ultra-wideband Siren 14, licensed by Polycom, codec. They do not support any full-band codecs.
