Enter a Fully Qualified Domain Name (FQDN) or IP address of an RTP sink; this value is used by the streaming audio server line in the SDP of its 200 response to an inbound INVITE message from a client. 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 a FQDN or IP address of a 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 and, if specified, in the m = line of the SDP. If this value is not specified or 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.

SAS Inbound RTP Sink
This setting works around devices that do not
play inbound RTP if the streaming audio server
line declares itself as a send-only device and
tells the client not to stream out audio. Enter a
Fully Qualified Domain Name (FQDN) or IP
address of an RTP sink; this value is used by the
streaming audio server line in the SDP of its 200
response to an inbound INVITE message from a
client.
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 a FQDN or IP address of a 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 and, if
specified, in the m = line of the SDP. If this value is
not specified or 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.
