There is an opus patch for asterisk 11. . But it doesn’t have Packet Loss Resilience or Forward Error Correction, both of which are important for voip.

2.1.6. Packet Loss Resilience

Audio codecs often exploit inter-frame correlations to reduce the bitrate at a cost in error propagation: after losing one packet, several packets need to be received before the decoder is able to accurately reconstruct the speech signal. The extent to which Opus exploits inter-frame dependencies can be adjusted on the fly to choose a trade-off between bitrate and amount of error propagation.

2.1.7. Forward Error Correction (FEC)

Another mechanism providing robustness against packet loss is the in-band Forward Error Correction (FEC). Packets that are determined to contain perceptually important speech information, such as onsets or transients, are encoded again at a lower bitrate and this re-encoded information is added to a subsequent packet.

There is an opus patch for asterisk 13 that includes PLR and FEC.

We don’t have approval to move to 13. So anybody have an opus patch for
11 that includes PLR and FEC ?
