User's Manual

[1] = (Default) Enable IP address translation.
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 IP address of the outgoing media stream
to the remote destination is obtained by the source IP address of the
first incoming packet.
Note: The NAT mechanism must be enabled for the parameter to take
effect. To enable NAT, see the NATMode parameter).

[0] = (Default) Disables UDP port translation.

[1] = Enables UDP port translation. The device compares the
source UDP port of the first incoming packet to the remote UDP
port stated in the opening of the channel. If the two UDP ports don't
match, the NAT mechanism is activated. Consequently, the remote
UDP port of the outgoing stream is replaced by the source UDP
port of the first incoming packet.
Note:

For the parameter to take effect, a device reset is required.

The NAT mechanism and IP address translation must be enabled
for the parameter to take effect, using the NATMode parameter and
the EnableIpAddrTranslation parameter, respectively.
Enables the device to detect whether the incoming INVITE message is
sent from an endpoint located behind NAT.

[0] Disable = Disables the device's NAT Detection mechanism.
Incoming SIP messages are processed as received from endpoints
that are not located behind NAT and sent according to the SIP
standard.

[1] Enable (default) = Enables the device's NAT Detection
mechanism.
Table 65-15: DNS Parameters
The table defines the internal DNS table for resolving host names into IP
addresses.
The format of the ini file table parameter is:
[Dns2Ip]
FORMAT Dns2Ip_Index = Dns2Ip_DomainName,
Dns2Ip_FirstIpAddress, Dns2Ip_SecondIpAddress,
Dns2Ip_ThirdIpAddress;
[\Dns2Ip]
For example:
Dns2Ip 0 = DnsName, 1.1.1.1, 2.2.2.2, 3.3.3.3, ;
