GO HERE What is the bitrate(s) of the opus codec in Asterisk?

Hi,
I've been wanting to enjoy the opus codec, and so far using Linphone (which is an excellent softphone and has opus) between two computers I can hear the amazing sound. But I wanted to hear music over it, so I converted a couple of tunes to .sln48, assuming asterisk would operate opus at that rate (* 13.) But when I call it with an opus phone the music is slow, seeming like it's misinterpreting the file, even though it's extension is right. Does anyone have any experience with opus like this?
Thanks,
Steve

It's a variable bit rate codec which means it will use as much or as little bandwidth as it can find in your Internet pipe. Typically, about 5 Opus calls can be squeezed into the same bandwidth as one ULAW call... with the same voice quality.
