Press
Local IP
button to find the IP address of your IP phone.
If you are connecting the phone to a router, the IP address
should normally be 192.168.xxx.xxx or 10.0.xxx.xxx. If it is
not, you need to check the RJ-45 cable connection, and
make sure the LAN port on your router is on and flashing
If you are using the static IP, please check the network
setting and make sure the static IP address, subnet mask,
and gateway address are entered and set correctly.
If you are using PPPoE, please check the network setting
and make sure the ppp id and ppp pin is set correctly.
Use web browser to visit the IP phone setting page. (Refer to
Configuration via Web Browser section on page 14) Consult
with your VoIP service provider and compare the “protocol”,
“proxy”, “service id”, “service addr”, “service port”, and
“account” fields of the protocol settings area. Then click
update button to reboot the phone.
If you still can not log on and you are using a router or a
firewall, check with your VoIP provider to find out the service
port required, and follow the instruction in Appendix to enable
Port Forwarding.
