Sticky 183
If set to yes, SPA will ignore further 180 SIP
responses after receiving the first 183 SIP
response for an outbound INVITE.
Bool no
SIP TOS/DiffServ
Value
TOS/DiffServ field value in UDP IP Packets
carrying a SIP Message
Byte 0x68
RTP TOS/DiffServ
Value
TOS/DiffServ field value in UDP IP Packets
carrying a RTP data
Byte 0xb8
SAS Enable
4
Enables the FXS Line to act as a Streaming Audio
Source (SAS). If enabled, the line cannot be used
for making outgoing calls. Instead, it auto-answers
incoming calls and streams audio RTP packets to
the calling party.
Bool No
SAS DLG Refresh
Intvl
4
If non-zero, this is the interval at which SAS sends
out session refresh (SIP re-INVITE) messages to
detect if connection to the caller is still up. If the
caller does not respond to refresh message, SPA
will terminate this call with a SIP BYE message.
The default = 0 (Session refresh disabled)
Range = 0-255 (s)
0
SAS Inbound RTP
Sink
4
The purpose of this parameter is to work around
devices that do not play inbound RTP if the SAS
line declares itself as a “sendonly” 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 SPA 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].
Str63
NAT Mapping Enable
Enable the use of externally mapped of IP address
and SIP/RTP ports in SIP messages. The mapping
may be discovered by any of the supported
methods.
Bool No
NAT Keep Alive
Enable
If set to “yes”, the configured <NAT Keep Alive
Msg> is sent periodically every <NAT Keep Alive
Intvl> seconds.
Bool No
NAT Keep Alive Msg
Contents of the keep-alive message to be sent to a
given destination periodically to maintain the
current NAT-mapping. It could be an empty string.
If value is $NOTIFY, a NOTIFY message is sent as
keep alive. If value is $REGISTER, a REGISTER
message w/o Contact is sent.
Str31 $NOTIFY
NAT Keep Alive Dest
Destination to send NAT keep alive messages to. If
value is $PROXY, it will be sent to the current
proxy or outbound proxy
FQDN $PROXY
SIP Debug Option
None, 1-line, full, exclude OPTIONS, exclude
Choice
none
