STUNServerPrimaryIP
For a description of this parameter, refer to ''Configuring the
Application Settings'' on page

STUNServerSecondaryIP
For a description of this parameter, refer to ''Configuring the
Application Settings'' on page
57 .
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.
ƒ
[0]
= Enabled.
ƒ
[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
Enables IP address translation.
ƒ
[0]
= Disable IP address translation.
ƒ
[1]
= Enable IP address translation for RTP, RTCP and T.38
packets (default).
ƒ
[2] = Enable IP address translation for RTP Multiplexing
(ThroughPacket™).
ƒ
[3] = Enable IP address translation for all protocols (RTP, RTCP,
T.38 and RTP Multiplexing).
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.
Notes:
ƒ
The NAT mechanism must be enabled for this parameter to take
effect (DisableNAT set to 0).
