So upgraded to SNG 7, wen’t fairly well without any major issues. Complains there are a lot of ‘Unsigned modules’ even though I haven’t made any of my own.
Aside from that my codecs.conf specifies a samprate=16000 and max_playback_rate=16000 but in the SDP it always shows 48000. On the active channel this also shows 48Khz. The only good news is from freepbx and from Zoiper they both send useinbandfec=1. It honestly doesn’t seem like fec works as on the OPUS comparison page the quality is still quite good with 30% packet loss, where here even with 10 its complete suffering.
