Parameter Description
SIPInterface 0 = Voice, 2, 5060, 5060, 5061, 1;
SIPInterface 1 = Voice, 2, 5070, 5070, 5071, 2;
SIPInterface 2 = Voice, 0, 5090, 5000, 5081, 2;
Notes:
 This table can include up to 32 indices (where 0 is the first index).
 Each SIP Interface must have a unique signaling port (i.e., no two SIP
Interfaces can share the same port - no port overlapping).
 You can define up to three different SIP Interfaces per SRD, where
each SIP Interface pertains to a different application type (i.e., GW,
SAS, and SBC).
 For a detailed description of the table's individual parameters and for
configuring the table using the Web interface, see ''Configuring SIP
Interface Table'' on page 117.
 For a description on configuring ini file table parameters, see ''Format
of ini File Table Parameters'' on page 368.
Static NAT Table
[NATTranslation]
This ini file 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 ]
Where:
 SourceIPInterfaceName = name of the IP interface as defined in the
Multiple Interface table.
 TargetIPAddress = global IP address.
 TargetStartPort and TargetEndPort = (optional) port range (1-65536)
of the global address. If no ports are required, leave this field blank.
 SourceStartPort and SourceEndPort = (optional) port range (1-65536)
of the IP interface. If no ports are required, leave this field blank.
Notes:
 This table can include up to 32 indices.
 The device’s priority method for performing NAT is as follows (not
relevant for SBC application):
a. Uses an external STUN server (STUNServerPrimaryIP
parameter) to assign a NAT address for all interfaces.
b. Uses the StaticNATIP parameter to define one NAT IP address
for all interfaces.
