this issue is really weird, i tried on national call. it's working well. I contacted my provider i can make international calls. if i try a lower bitrate like 128kbps is ok (2 channels it's working)

Other things i tried this call on another rmx with a bitrate configured at 384 kbps it's ok (it's a polycom test number)

if you can help me on this issue it will be great
