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.
NAT Mapping Enable
To use externally mapped IP addresses and SIP/RTP ports in SIP
messages, select yes. Otherwise, select no.
The default is no.
NAT Keep Alive Enable
To send the configured NAT keep alive message periodically, select
yes. Otherwise, select no.
The default is no.
NAT Keep Alive Msg
Enter the keep alive message that should be sent periodically to
maintain the current NAT mapping. If the value is $NOTIFY, a
NOTIFY message is sent. If the value is $REGISTER, a
REGISTER message without contact is sent.
The default is $NOTIFY.
NAT Keep Alive Dest
Destination that should receive NAT keep alive messages. If the
value is $PROXY, the messages are sent to the current proxy server
or outbound proxy server.
The default is $PROXY.
