Yealink recently released OPUS capable firmware for some of their phones. I'm trying to get this to work but am having some final issues I need some help with.
Asterisk version is 13.14.0
I can place calls and everything is functional.
The problem is that the audio is choppy from asterisk>yealink. Not completely, but it has little breaks like g.711 with a bit of packet loss. yealink>asterisk is fine, if I connect up a g.711 call the yealink(opus)>asterisk>g.711 endpoint is clean.
PBX is remote, but 10ms away with no packet loss and jitter peaks at about 10ms. I run icmp pings across to try to track the gaps to any kind of loss but see no correlation. I capture a PCAP and there are no missing packets.
Any ideas what might be causing this? I've tried many different bitrates and complexity but they all behave the same. Evan a complexity=1 8kbps stream has this as does a compleixty=10 48kbps stream..
Thanks for any help.
