That depends.
Initially, RTP data is sent via Asterisk (B). Asterisk will then try to
reinvite A and C so RTP is sent directly between them. If it succeeds, RTP
is stent only between A and C, if it doesn't, asterisk will act as a
proxy. If the reinvite succeeds but a firewall is blocking the direct RTP
stream, the call will get silent. You'll have to put "canreinvite=no" in
the sip.conf for at least one of the ata186 devices in that case, so it
doesn't even try...
Cheers,
Siggi
