Title Explanation
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.
RTP Receiving Port
The gateways will send the RTP receiving port selected here to the
remote side.
l NAT port: Use NAT mapped port，which is obtained through STUN,
for example;
l Local port: Use local SIP and RTP port.
Remote
management
Remote
management
The gateways support EMS which is a centralized gateway management
server provided by New Rocj, and Auto-provision.
EMS
Primary server User needs to enter the IP address and port of EMS server for activating
EMS service.
Secondary server User needs to enter the IP address and port of standby EMS server for
activating EMS service. EMS server address could be set into IP or
domain name according to the user’s requirement. If adopt domain name
as the address, the user should activate the “DNS service” as shown in
the page of “Configure network parameter”, and configure the
parameter(s) of “DNS server”. The complete and valid configurations are
exampled as: “201.30.170.38:5060” and “softswitch.com:5060”.
Log level Gateway sends the log file level to EMS server, and the default value is
4. The parameter is controlled by EMS server, and users should not make
any modification.
Message retransfer
interval
This is the retransmission counter for message transmitting between the
gateway and EMS server. The default is 3. The parameter is set by EMS
server, and users should not make any modification.
Registration period Gateways will perform registration to the EMS server periodically based
on the time interval set here. With second as unit, default is 15. The
parameter is set by EMS server, and users should not make any
modification.
Auto provision
Server Gateways may download software upgrade packages and configuration
files automatically through auto-provision server. Once the auto
provision is selected, you have to enter the IP address of ACS here.
