Thanks!  It's interesting that Silk is less CPU intensive than Opus.  However, at this point I would be willing to spend extra CPU cycles if it gets me more consistent call quality on an iffy connection.

Anyone has experience with this?

Of course jitter buffer is independent from codec, but its functionality affects the quality.

Yes SILK is inherited by Opus, but in general SILK is much cheaper in terms of CPU cycles for encoding and decoding.

You can see the difference here: https://txlab.wordpress.com/2015/04/10/testing-freeswitch-performance-on-scaleway-c1/

Thanks Stanislav!

I understand that jitter buffer is not necessarily codec dependent and that SILK is actually the foundation of Opus, so I assume their quality is comparable.

add SILK to the list (it's actually what Skype uses), and jitter buffer.

but I don't have much practical experience.

The quality of the sound depends also on the particular SIP client
implementation.
