Configuring GrandStream GXP-2000 for 3CX Phone System

IMPORTANT This guide has been tested with the following system information: Program-- 1.1.4.18 Bootloader-- 1.1.4.6. Be aware that different firmware revisions may have different web interface formats and functionality. See compatibility list for latest phone firmware revisions that we have tested with 3CX Phone System.

  1. Ensure that you have created the extension that you wish to use with the phone in 3CX Phone System first. Take note of the ID field and the password that you have entered for the extension.
  2. Connect the GrandStream GXP-2000 phone to the network and mains power supply. The phone will boot up, and providing you have DHCP installed on your network, will obtain an IP and display it at the bottom of the phone’s LCD screen.
  3. Now point your browser to the web interface of the phone: ‘http://’ where is the IP address shown on the phone.
  4. Enter the password of the phone and click login to access the phone’s configuration. For this particular phone, the default password is “admin”.


    GXP-2000 Account configuration page

  5. Click on ‘Account 1’ from the available links at the top of the page.
  6. Now configure the account for the phone. First of all make sure that ‘Account Active’ is set to YES. Enter an account name for the phone in the ‘Account Name’ box. This setting is not used by 3CX Phone System. It is only used when making calls to other phones directly.
  7. In the SIP server field, enter the IP or FQDN name of the 3CX Phone System server. If entering an FQDN, review this FAQ.
  8. Repeat the same setting for the Outbound Proxy option
  9. Enter the extension number you want to associate with this phone in the ‘SIP User ID’ setting.
  10. Now enter an ‘Authenticate ID’ & ‘Authenticate Password’ in the appropriate fields. These fields must match the ID & password configured in the ‘ID’ & ‘Password’ fields in the Authentication section of the ‘Add Extension’ page in the 3CX Management Console.
  11. Scroll to the bottom of the page and press ‘Update’ to save these settings.
  12. Click ‘Reboot’ to reset your GrandStream phone and put your changes into effect.
  13. When the phone boots, it should register with 3CX Phone System.
  14. Now switch to the 3CX Phone System Management console, and click on Phone System > ‘Line Status’ (This is the default page). The extension should be listed, and the status should show ‘Registered (idle)’.

Entering the IP address manually if you do not have a DHCP server

If you don’t have a DHCP server, you will need to assign an IP address to the phone before you can access it. To do this:

  1. Press the round ‘menu’ button in the top right corner once to activate the menu. You will see the words ‘[1] Do Not Disturb -Off’ on the phone’s LCD screen.
  2. Press the down arrow (in the same group of buttons) ONCE to navigate to ‘[2] DHCP/PPOE mode’. If instead you see ‘[2] Static IP Mode’, skip to #6.
  3. Press the round menu button twice to disable DHCP mode. On the phone’s screen you should now see ‘[2] Static IP Mode’.
  4. Press the down arrow once to get to the ‘[3] IP address menu’. Press the round menu button once and key in your desired IP address on the phone’s numeric keypad, allowing 3 digits for each octet and leaving out the dots in between. For e.g. 192.168.1.15 would be keyed in as 192168001015. When ready press the round menu button to save this IP address in the phone’s configuration.
  5. Press the down arrow to go to the Subnet Mask configuration. Press the round menu button once and type in your subnet mask using the same concept as when entering the IP address in #6 (e.g. 255.255.255.0 should be keyed in as 255255255000). Once ready press the round menu button to save the subnet mask.
  6. Press the down arrow multiple times until you get to ‘--RESET--’ on the LCD screen and then press the round menu button to reboot the phone and activate the new settings.

MWI (Message Waiting Indicator) Functionality:

The 3CX Phone System can deliver MWI updates to the GXP2000. To use such feature, enable "SUBSCRIBE for MWI" by ticking the "yes" option under account settings.

NOTE: This feature (MWI) is not available in the Free Version of 3CX Phone System. The MWI feature is available in all other versions.

Configuring BLF (busy lamp field) on a Grandstream GXP2000 or GXP2020 and 3CX Phone System v5

To configure BLF on a Grandstream GXP2000 or GXP2020 phone one needs to access the phone’s web interface via a web browser. In our example it is assumed that the phone has IP address 10.172.0.100 and the 3CX Phone System in installed on IP address 10.172.0.2.

Click on “Basic Settings” on top to configure BLF. Go towards the middle of the screen go to “Multi Purpose Key” section. In this example we are configuring key 1 and 2. In the “Name” field and the “UserID” field type the extension that will be monitored regarding its status. Then click the “Update” button. Finally press the “Reboot” button. BLF is now configured.

NOTE:
* This feature (BLF) is not available in the Free Version of 3CX Phone System. The MWI feature is available in all other versions.
