[Freeswitch-users] OPUS - is FS ignoring incoming FAC packets?

Hello all, Wondering if anyone's seen this scenario: With 15% packet loss, FEC enabled. - sip -> pstn: -- We're seeing FEC out and in * client (OPUS) --> FS --> (PCMU/A) B-leg - Result: Choppy Audio * client (OPUS) <-- FS <-- (PCMU/A) B-leg - Result: Very good audio * client (OPUS) --> FS --> client (OPUS) - Result: Very good audio * client (OPUS) <-- FS <-- client (OPUS) - Result: Very good audio It's like FS is ignoring the incoming FEC when transcoding. I have a small jitterbuffer 20:100:20 Any ideas? David Villasmil email: david.villasmil.work@gmail.com phone: +34669448337
