SIP User's Manual 4. ini File Configuration
ini File Parameter Description
Notes:
 If the Internal SRV table is used, the device first attempts to resolve a
domain name using this table. If the domain name isn't located, the
device performs an SRV resolution using an external DNS server.
 This parameter can include up to 10 indices.
 To configure the Internal SRV table using the Web interface, refer to
''Internal SRV Table'' on page 208.
 For an explanation on using ini file table parameters, refer to
''Structure of ini File Table Parameters'' on page 293.
EnableSTUN
For a description of this parameter, refer to ''Configuring the Application
Settings'' on page 71.
STUNServerPrimaryIP
For a description of this parameter, refer to ''Configuring the Application
Settings'' on page 71.
STUNServerSecondaryIP
For a description of this parameter, refer to ''Configuring the Application
Settings'' on page 71.
STUNServerDomainName
Defines the domain name for the Simple Traversal of User Datagram
Protocol (STUN) server's address (used for retrieving all STUN servers
with an SRV query). The STUN client can perform the required SRV
query to resolve this domain name to an IP address and port, sort the
server list, and use the servers according to the sorted list.
Note: Use either the STUNServerPrimaryIP or the
STUNServerDomainName parameter, with priority to the first one.
NATBindingDefaultTimeo
ut
Defines the default NAT binding lifetime in seconds. STUN is used to
refresh the binding information after this time expires.
The valid range is 0 to 2,592,000. The default value is 30.
DisableNAT
Enables / disables the Network Address Translation (NAT) mechanism.
 [0] = Enabled.
 [1] = Disabled (default).
Note: The compare operation that is performed on the IP address is
enabled by default and is controlled by the parameter
EnableIPAddrTranslation. The compare operation that is performed on
the UDP port is disabled by default and is controlled by the parameter
EnableUDPPortTranslation.
EnableIPAddrTranslation
 [0] = Disable IP address translation.
 [1] = Enable IP address translation for RTP, RTCP and T.38 packets
(default).
 [2] = Enable IP address translation for ThroughPacket™.
 [3] = Enable IP address translation for all protocols (RTP, RTCP, T38
and ThroughPacket™).
When enabled, the device compares the source IP address of the first
incoming packet, to the remote IP address stated in the opening of the
channel. If the two IP addresses don't match, the NAT mechanism is
activated. Consequently, the remote IP address of the outgoing stream is
replaced by the source IP address of the first incoming packet.
Note: The NAT mechanism must be enabled for this parameter to take
effect (DisableNAT = 0).
