Parameter Description
[\SIPInterface]
Note: For a detailed description of this table, see 'Configuring SIP
Interface Table' on page 227 .
TCP Keep Alive Idle Time
[TCPKeepAliveTime]
Defines the interval (in sec) between the last data packet sent and the
first keep-alive probe to send.
The valid value is 10 to 65,000. The default is 60.
Notes:

Simple ACKs such as keep-alives are not considered data packets.

TCP keepalive is enabled per SIP Interface in the SIP Interface
table.
TCP Keep Alive Interval
Time
[TCPKeepAliveInterval]
Defines the interval (in sec) between consecutive keep-alive probes,
regardless of what the connection has exchanged in the meantime.
The valid value is 10 to 65,000. The default is 10.
Note: TCP keepalive is enabled per SIP Interface in the SIP Interface
table.
TCP Keep Alive Retry
Number
[TCPKeepAliveRetry]
Defines the number of unacknowledged keep-alive probes to send
before considering the connection down.
The valid value is 1 to 100. The default is 5.
Note: TCP keepalive is enabled per SIP Interface in the SIP Interface
table.
NAT Translation Table
Web: NAT Translation
Table
[NATTranslation]
This table parameter defines NAT rules for translating source IP
addresses per VoIP interface (SIP control and RTP media traffic) into
NAT IP addresses. This allows, for example, the separation of VoIP
traffic between different ISTP’s, and topology hiding (of internal IP
addresses to the “public” network). Each IP interface (configured in the
Multiple Interface table - InterfaceTable parameter) can be associated
with a NAT rule in this table, translating the source IP address and port
of the outgoing packet into the NAT address (IP address and port
range).
The format of this parameter is as follows:
[ NATTranslation ]
FORMAT NATTranslation_Index =
NATTranslation_SourceIPInterfaceName,
NATTranslation_TargetIPAddress, NATTranslation_SourceStartPort,
NATTranslation_SourceEndPort, NATTranslation_TargetStartPort,
NATTranslation_TargetEndPort;
[ \ NATTranslation ]
Note: For a detailed description of this table, see 'Configuring NAT
Translation per IP Interface' on page 140 .
