Streaming Audio Server (SAS) section
SAS Enable
To enable the use of the line as a streaming audio source,
select yes. Otherwise, select no. If enabled, the line cannot
be used for outgoing calls. Instead, it auto-answers
incoming calls and streams audio RTP packets to the caller.
The default is
no
.
SAS DLG Refresh
Intvl
If this value is not zero, it is the interval at which the
streaming audio server sends out session refresh (SIP re-
INVITE) messages to determine whether the connection to
the caller is still active. If the caller does not respond to the
refresh message, the WRP400 ends this call with a SIP BYE
message. The range is 0 to 255 seconds (0 means that the
session refresh is disabled).
The default is
30
.
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.
The default value is empty.
