Curious to know which other VoIP solutions implement this.
Been googling around for error-correction (parity?) which adds some realtime repair capabilities to deal with random packet loss (but obviously not big drops of consecutive packets). Found this interesting article that seems to suggest Skype (for business) is doing it for some small overhead cost, and maybe a slight latency cost.

This is interesting interesting because we're seeing more and more calls and video conferencing done over WiFi or 3G. I'd be super onboard with having a VoIP codec/protocol that totally masks packet loss, the alternative IT best practice being "duurrrr use wired, durrrr fix ur network durrrr". "You can't fix congested networks by adding more data durrrrr you're going to break everything listen to me I'm an expert durrr !"
I don't have a particular use-case in mind but when I consult in the future for a VoIP (or Videoconf) deployment I'd definitely lean towards something that could eliminate packet loss without just using lossy audio masking techniques .
EDIT: Looks like OPUS can enable FEC if supported at the phone and PBX end. Zoiper supports it, asterisk too. Maybe Skype, Facebook, and hangouts all have FEC enabled already...
