ISSUE SOLUTION
LCD reads:
“wait logon…” or “logon failed”
Press Local IP button to find the IP address of your IP phone.
If it shows 0.0.0.0, it means the Internet connection is down,
please check the LAN cable and modem.
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. Consult
with your VoIP service provider and compare the “phone
numbert”, and “account” fields of the protocol settings area.
Then click update button to reboot the phone.
Possible causes:
Firewall: When network firewall is enabled, it may cause
logon failed. We suggest user open the UDP ports 1719 and
1115; TCP ports 1720, 80, and 8080. Also open UDP port
above 5000.
Modem compatibility: Some 2 in 1 modem/router device
may have compatibility issue with VoIP devices. Please try to
use a separate router.
I can not hear dial tone from the
IP phone hand set
Make sure the phone cord is tightly connected to both
handset and phone set.
Check the volume level by pressing the volume+ button.
When I dial a phone number, I
always hear fast busy tone.
When dial the phone number, make sure you follow the
dialing rule of your VoIP service provider (i.e. 1-area
code-888-1234 for US phone numbers). Please check with
your VoIP service provider for detail.
If you are using pre-paid VoIP service, please make sure you
have enough balance on your account.
