[Freeswitch-users] Automatic transcoding does not seem to occur.

I've got a client with OPUS and G.711 codecs enabled and FreeSWITCH with OPUS and G.711 codecs enabled. I've got a SIP gateway connected to FreeSWITCH with only support for G.711. I want to have clients only use OPUS codec - as this seems best for mobile data connections. As of now client <-> FS <-> client use OPUS, but whenever the SIP gateway is involved G.711 is chosen. If I disable G.711 codec on the client side, to force OPUS, I'm not allowed to dial out via my SIP gateway. So transcoding to G.711 does not occur. My fs_cli reports this: Hangup sofia/external/+4413265874 [CS_CONSUME_MEDIA] [SERVICE_NOT_IMPLEMENTED] Again, reenabling G.711 in the client and everything works. I have not set disable-transcoding=true. What to do?
