1-6 QUICK SETUP
Note:
Please use Windows XPIE 6.0 web browser or above version to
configure FXO gateway webpage setting. Welltech products don’t
support otherWeb Browser such as FireFox to configure.
Login :
Setp1: Setup the administrative PC’s IP address to be same as Wellgate 2504
and connect the Ethernet cable into WAN or LAN port. Start IE6.0 (or later
version) to navigate Wellgate 2504 web management system by typing the
default URL which is http://192.168.123.123 (through LAN port) or
http://10.1.1.3 (through WAN port).The screen will display User Name
and Password (the default user id is root and user password is root). (See
figure 1-6-1 web access)
Figure 1-6-1 web access

Step 2: After login, the screen shows the Home page of Wellgate 2504. (See
figure 1-6-2 Network configure-1)
Figure 1-6-2 Network configure-1
Change Default IP Network:
Step 3: After successfully logon to the system, we need to change the
network configuration. Click Device Setting > Network to setup the service
network interface (WAN) parameters. Enter the deserved IP address, netmask
and default gateway or selected to “DHCP” or “PPPOE”. Apply the change by
clicking Apply button as fig (See Figure 1-6-3 Network configure-2).
Note: If Gateway WAN port are setting in the 10.x.x.x segment, please make
sure that you also change the LAN port to other segment such as 192.168.x.x
Figure 1-6-3 Network configure-2

9
Change Default Time setting:
Step 4: When re-logon to the new IP address, the next is to setup the system
time zone. Click Device Setting > Time to setup the system. Enter the
current SNTP server, time zone and daylight saving parameters. Apply the
change by clicking Apply button. (See figure 1-6-4 Time setting)
Figure 1-6-4 Time setting
Modify SIP Account Parameter:
Step 5: The next step is to add a SIP trunk for VOIP calling. For Wellgate 2540,
it is necessary for VOIP calling while wellgate 2504 is optional. Click SIP
trunk and new to create the required sip trunk. Enter the trunk ID to 1 and
input those SIP parameters. Apply the change by clicking Apply button. (See
Figure 1-6-5 SIP Trunk).
Note: please don’t delete sip trunk, even it is unless at all, because it have to
be used with Route plan.
