Opus Rightones

[Frazer]

Hi,
We are considering buying around 60 T-46S.
It would be great if the T-4xS range could support the Opus format for ringtones and any other audio related feature - reducing space, improving quality.

https://people.xiph.org/~jm/opus/opus-1.2/ - Check out Opus v1.2 versus MP3 @ 32kbit/sec

I'm hoping the the built in speaker capable of producing better quality than the link below?

What version of Opus does the x.82.0.20 firmware for T-4xS range use currently?

Opus v1.2 also reduces CPU requirements - is there a time frame to upgrade to the latest Opus version if it is not already included in firmware x.82.0.20?

Thanks
