SAS Inbound RTP
Sink
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.
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.
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.
