AudioCodes Mediant 500L - DNS Parameters

Version 7.2 1025 Mediant 500L Gateway & E-SBC
User's Manual 69. Configuration Parameters Reference
Parameter Description
Option, by default.
For more information on NAT traversal, see ''First Incoming Packet
Mechanism'' on page 159.
[NATBindingDefaultTimeout] The device sends SNMP keep-alive traps periodically - every 9/10 of
the time configured by the parameter (in seconds). Therefore, the
parameter is applicable only if the SendKeepAliveTrap parameter is
set to 1.
The parameter is used to allow SNMP communication with
AudioCodes OVOC management platform, located in the WAN, when
the device is located behind NAT. It is needed to keep the NAT pinhole
open for the SNMP messages sent from OVOC to the device.
The valid range is 0 to 2,592,000. The default is 30.
Note: For the parameter to take effect, a device reset is required.
SIP NAT Detection
configure voip > sip-
definition advanced-settings
> sip-nat-detect
[SIPNatDetection]
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.

[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, ;
For more information, see ''Configuring the Internal DNS Table'' on page
