I have that flag ticked. There are two distinct cases.

1. The phone makes an outgoing call (actually to voicemail on the remote
SIP server). All RTP traffic goes direct from the remote host to the
local phone bypassing opensbc. it is bidirectional.

2. I make an incoming call from the remote SIP server. The call is
handled by opensbc and the local phone rings. When the phone is answered
the SDP handshake managed by opensbc directs both the remote SIP server
and the local phone to send packets to 0.0.31.64 - so no sound on the
phone and no traffic through opensbc.

It would appear that the note "Enable proxying media on all incoming
call" on the "General Parameters" "Always Proxy Media" is literal - only
incoming calls are proxied.

It would also appear that there is a bug in the code setting up the RTP
proxy. Possibly this is due to me running on fully routable addresses?
