3.6 IP Configuration
You must configure the IP address, subnet mask and default gateway so that the PBX VoIP Gateway is able
to connect to the IP network. Since the device provides a 10BASE-T/100BASE-TX Ethernet interface with a
default auto-negotiation setting, it should work like a plug-and-play device; therefore a manual configuration
should seldom be necessary.
The system provides two types of IP assignment:
1. Manually assigned (static)
1
2. DHCP server assigned
You can use the IP state command to select the appropriate mode that is used by your network. The default
value is set to manually assigned. On the first time of setting up the gateway, you must assign the IP
address manually. If you want the gateway to receive the IP address from a DHCP server, you must set the
IP state mode to DHCP mode. If a DHCP server is used, it will request the IP address from the server.
However, if the DHCP server does not respond within one minute, the system will attempt to use the
manually assigned IP address.
Please note that when the system is in DHCP mode, the IP address received from the DHCP server
will be saved in the configuration file, so if the PBX Gateway is unable to request an IP address
from the DHCP server during the next boot up, this IP address will then be used.
Modifications will not take effect until after your system is restarted .

While operating under a NAT environment, it is better to have a static IP address and redirect the port number to this static IP to provide
remote managed access from the Internet.
