Web: Bronze QoS
EMS: Bronze Service Class Diff Serv
[BronzeServiceClassDiffServ]
Defines the DiffServ value for the Bronze CoS
content (OAMP applications).
The valid range is 0 to 63. The default value is 10.
43.1.5 NAT and STUN Parameters
The Network Address Translation (NAT) and Simple Traversal of UDP through NAT
(STUN) parameters are described in the table below.
Table 43-5: NAT and STUN Parameters
Parameter Description
STUN Parameters
Web: Enable STUN
EMS: STUN Enable
[EnableSTUN]
Enables Simple Traversal of UDP through NATs (STUN).
 [0] Disable (default)
 [1] Enable
When enabled, the device functions as a STUN client and
communicates with a STUN server located in the public Internet.
STUN is used to discover whether the device is located behind a
NAT and the type of NAT. It is also used to determine the IP
addresses and port numbers that the NAT assigns to outgoing
signaling messages (using SIP) and media streams (using RTP,
RTCP and T.38). STUN works with many existing NAT types and
does not require any special behavior from them.
Notes:
 For this parameter to take effect, a device reset is required.
 For defining the STUN server domain name, use the parameter
STUNServerDomainName.
 For more information on STUN, see Configuring STUN on page
127.
Web: STUN Server Primary IP
EMS: Primary Server IP
[STUNServerPrimaryIP]
Defines the IP address of the primary STUN server.
The valid range is the legal IP addresses. The default value is
0.0.0.0.
Note: For this parameter to take effect, a device reset is required.
Web: STUN Server Secondary
IP
EMS: Secondary Server IP
[STUNServerSecondaryIP]
Defines the IP address of the secondary STUN server.
The valid range is the legal IP addresses. The default value is
0.0.0.0.
Note: For this parameter to take effect, a device reset is required.
[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.
Notes:
 For this parameter to take effect, a device reset is required.
 Use either the STUNServerPrimaryIP or the
