Quick Start Guide
Congratulations on the purchase of your
Internet telephone!
Your telephone is already pre-configured for your sipgate account, so that you can attach
it directly to your Internet connection. Please proceed as follows:
First steps with the GXP-2000
Start-up of your GrandStream GXP-2000 Enterprise IP-Telephone
Connected?
After the automatic update, the display lights up blue again and
should show the current time. Your telephone is now operation-
al. If you lift the handset you will hear a dial tone.
You are now reachable on your sipgate phone and can call
sipgate numbers, free o8oo numbers in the United Kingdom and
over 1 million customers in partner networks. For other calls,
such as those to normal fixed-lines (pstn), or mobile phones you
will need credit on your sipgate account. To add money to your
account login and go to account & billing tab and you will see
how to credit your sipgate account.
First attach the handset by connecting the enclosed coiled cable to the
handset base plug on the left side of the telephone.
Attach the telephone with the enclosed network cable to your Internet
connection. One end of the cable must be connected to a 10/100 Mbit
Ethernet port (e.g. on a router). The other end has to be connected to
rear wall of the telephone. Your router must be set to assign an IP address
automatically to the telephone by DHCP. You may need to adjust your router
to do this.
Attach the power cable. The appropriate socket is directly beside the net-
work connection on the back of the base unit.
First start: The first time the telephone starts, the display lights up blue and
the device will do a firmware upgrade. Please wait while the telephone boots
completely and do not interrupt this process or you may damage the phone.

voicemail.

Troubleshooting
Other error messages and problems
Problem: I do not see a time in the display! Why is that?
Answer: Take the handset off and press “menu”. Press the down arrow
key and “menu” again. If you should see a set of all zeros 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 at least 10 Mbit/s .
Problem: I see no time in the display but the IP adress is being displayed.
Answer: Please make sure that your router has an active Internet connec-
tion (e.g. by trying to go to an Internet site from your computer). If this
is the case, the hints in the box above right will help. It usually means
your GPX2000 is having trouble reaching the Internet.
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 10,000. If you hear the
announcement, the telephone is correctly configured. If you hear some-
thing in German, it is not correctly configured.
Problem: I see the correct time, but I can’t call out. In the display I see
“404“ if I try to call another sipgate customer.
Answer: The customer you tried to call probably did not connect his IP
telephone correctly to our server. This can be because of a firewall prob-
lem or the Internet connection of the other person is down.
Problem: I can call out but I cannot hear the other person or the person
cannot hear me.
Answer: This is a configuration problem in 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 on DMZ and register the IP address of your
GXP2000. You may find out this address by pressing the menu button, the
down arrow and the menu button again.
2. Switch off all packet filter and Firewall options
Try turning off your active packet filters. These options can be found in
the web configuration menu of your router under „package filters“, „hacker
defence“, „IP filter“, „firewall“ or similar. Switch these options off.
3. Port forwarding
Arrange port forwarding for the following ports: port 5060/UDP (SIP signal-
ling), port 5004/UDP (RTP), port 10000/UDP (STUN).
4. UPnP
In case your router is UPNP (universal Plug and Play) supported, please try
turning this option on and/or off.
!It rings at the called end, however you hear no
voice when someone answers.
You can dial a number, but hear no ringing. As
soon as someone answers, the line disconnects.
Your sipgate number is not reachable.
The phone you called continues to ring, al-
though you have already hung up.
You can’t dial out.
The call terminates after 6 - 12 seconds.
Also typical for some of these problems: You may
not be able to reproduce them, but sometimes
emerge only after hours or days.

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

Configuration of your network
Should there be problems with the GXP2000 once everything has been
put together or problems emerge after some time, it is usually due to
incorrect routing and/or firewall configuration settings. Examples of
