Problem: I do not see a time in the display! Why is that?
Answer: Take the handset off and press „menu“. If you should see a set of
all zeros, then make sure that your router has the DHCP function turned
on so your phone can get an IP address. Please also make sure that your
router or switch has a bandwidth range of 10 Mbit/s (some devices
exclude connections with 1oo Mbit/s).
Problem: I do not see a time in the display! The IP address seems to be
there. If I take the listener off and press the menu key, then I see differ-
ent numbers - not only to zeros.
Answer: Please make sure that your rout has an active Internet connec-
tion (by trying e.g. from your computer to go to an Internet site). If this
is the case, the references in the box above will help.
Problem: I see the correct time, but I can’t call anyone. In the display I
see „403“ if I try to call another sipgate customer.
Answer: Try to select a call number, which you know works, like the test
number for sipgate. Call the test number 10000. If you hear the an-
nouncement, the telephone is correctly configured.
Problem: I see the correct time, cannot however not telephone. In the
display I see „404“ if I only try to call another sipgate customer.
Answer: The customer you would like to call, probably did not connect
their IP telephone correctly with our server. This can be e.g. because the
Internet connection of the other person was interrupted.
Problem: I call but I cannot hear the other person or the person cannot
hear me.
Answer: This is a configuration problem at your router. The box above
right contains further information to resolve this problem.
Problem: I can dial, but I don’t hear a dial tone, the person on the other
How you can eliminate these problems:
1. Activate the DMZ for the IP address of the telephone
The DMZ (Demilitarised zone) excludes a range of one or more IP addresses
from all Firewall settings. Usually you can find the option DMZ in the menu
of your router under „Firewall“, „Advanced Settings“, „WAN Settings“ or
„Applications/Gaming“. Switch the DMZ on and register the IP address of
your equipment. You may find out this address, by taking the handset off,
pressing the large button on the ATA, then dialling „0“ and „2“ on your
telephone. Listen for the IP address.
2. Switch off all packet filter and Firewall options
With some routing problems, the first step is sufficient. If not, try turning
off your active packet filters. Sometimes you must also change individual
settings like „package filters“, „hacker defence“, „IP filter“ or similar set-
tings „Firewalls“. Switch these options off.
3. Portforwarding
Arranging port forwarding for the following ports: port 5060/UDP (SIP
signalling), port 5004/UDP (RTP), port 10000/UDP (STUN).
4. UPnP
In case you router is UPNP (universal Plug and Play) supported, please try
turning this option on and/or off.

end hears it ring, but I can’t hear their phone ringing from my end.
Answer: This is a configuration problem at your router. The red box left
contains further information to resolve this problem.

data“/“Connection data”/“SIP password“.

Should the equipment not function once everything has been put
together or it has problems after some time, it is usually due to incorrect
