[Freeswitch-users] WebRTC Originate -> INCOMPATIBLE_DESTINATION

[Igor Olhovskiy]

Hi!
Seems to be I’ve got one of transcoding problem, that can’t solve.
Read https://freeswitch.org/confluence/display/FREESWITCH/Codec+Negotiation
back and forth.

I’m starting originate command with this
{bypass_media=false,media_mix_inbound_outbound_codecs=true,inherit_codec=false,proxy_media=false}sofia/gateway/CD5E5A11-88C7-4CC8-BA7A-7D2D3A7D9061/+XXXSOMENUMBER
&bridge({inherit_codec=false,proxy_media=false,media_mix_inbound_outbound_codecs=true,bypass_media=false}user/8C9686C8-C09D-D68A-2049-10646BDAF82E)

user/… is a WebRTC client.

Than I’ve got http://pastebin.com/SdnwjVbP in FS log.

Most interesting parts for me
