Table 5-13 Advanced System Configuration Parameters
Name Description
N A T
NAT traversal Gateways support several mechanisms for NAT traversal. Usually, static NAT is used when
fixed public IP address is available. It’s necessary to perform port mapping or DMZ function
on router when choosing dynamic or static NAT.
Refresh period The refresh time must be filled in here when choosing dynamic NAT or STUN traversal.
Besides, refresh time interval shall be determined by giving consideration into the NAT
refresh time of the LAN router which the gateway is located. Gateway’s NAT holding
function and STUN function will carry out periodically operation according to this
parameter. With second as its unit, default value of 60 seconds.
SDP Address
This parameter determines the IP address used in transmitted SDP.

NAT IP Address: Apply NAT address into the transmitted SDP;

Local IP Address: Apply the gateway’s IP address into the transmitted SDP.
Note: The parameter should come into effect only on condition that gateway successfully
obtained NAT address.
NAT IP address This parameter must be filled when using static NAT traversal, in which IAD works under
LAN and the WAN address is fixed. The WAN address should be filled in this field, which
will be used in SDP. This parameter can be set in IP address format or hostname format
(note: DNS service should be activated when hostname format is used). There is no default
value for this field.
STUN server Set the IP or domain name of STUN server. No default value. If the set is empty, the
gateway will adopt the STUN server address configured at factory.
When choosing STUN for NAT traversal, the gateway will carry out STUN operation
periodically according to the configured interval time of NAT refresh.
RTPReceivingPort
The gateways will send the RTP receiving port selected here to the remote side.

NAT port: Use NAT mapped port
，
which is obtained through STUN, for example;

Local port: Use local SIP and RTP port.
Auto Provision

Configuration Manual .
Enable Tick it to use the auto provision function.
DHCP ACS (Auto Provisioning Server) address is obtained by using DHCPoption66.
Server Manually configure the ACS address, which can be the TFTP, FTP, or HTTP server.

tftp://ACS address

ftp:// ACS address

http:// ACS address
Firmware upgrade Supports firmware download and update using ACS.
Update mode The following modes are available.

Power on: the gateway detects whether there are configurations and firmware to be
updated when the device is powered on.

Power on + Periodical: when the device is powered on, the gateway first checks whether
there are configurations and firmware to be updated, and then periodically performs
checking based on the set times.
Interval( minutes) When Power on+Periodical is set, this parameter specifies the interval for periodic
automatic upgrades.
TR069
Server To use the TR069 network management, you have to enter the IP address of ACS here.
