<SAS_Inbound_RTP_Sink_1_>
<SAS_Inbound_RTP_Sink_2_>
The purpose of this parameter is to work around devices that
do not play inbound RTP if the SAS line declares itself as a
send-only device and tells the client not to stream out audio.
This parameter is an FQDN or IP address of an RTP sink to be
used by the SAS line in the SDP of its 200 response to
inbound INVITE from a client. It will appear in the c = line and
the port number, if specified, will appear in the m = line of the
SDP. If this value is not specified or is equal to 0, then c =
0.0.0.0 and a=sendonly will be used in the SDP to tell the SAS
client to not to send any RTP to this SAS line. If a non-zero
value is specified, then a=sendrecv and the SAS client will
stream audio to the given address. Special case: If the value is
$IP, then the SAS line’s own IP address is used in the c = line
and a=sendrecv. In that case the SAS client will stream RTP
packets to the SAS line.
