Configuration via Web Browser

The GXP2130/GXP2140/GXP2160/GXP2170/GXP2135 embedded Web server responds to HTTP/HTTPS GET/POST requests. Embedded HTML pages allow a user to configure the IP phone through a Web browser such as Google Chrome, Mozilla Firefox, and Microsoft Edge.

To access the Web GUI:

1. Connect the computer to the same network as the phone.
2. Make sure the phone is turned on and shows its IP address. You may check the IP address by pressing the Up arrow button when the phone is in an idle state.
3. Open a Web browser on your computer.
4. Enter the phone’s IP address in the address bar of the browser.
5. Enter the administrator’s login and password to access the Web Configuration Menu.
   

Notes:

• The computer must be connected to the same sub-network as the phone. This can be easily done by connecting the computer to the same hub or switch as the phone is connected to. In the absence of a hub/switch (or free ports on the hub/switch), please connect the computer directly to the PC port on the back of the phone.
• If the phone is properly connected to a working Internet connection, the IP address of the phone will display in MENU → Status → Network Status. This address has the format: xxx.xxx.xxx.xxx, where xxx stands for a number from 0-255. Users will need this number to access the Web GUI. For example, if the phone has an IP address 192.168.40.154, please enter “http://192.168.40.154” in the address bar of the browser.
• There are two access levels for the login page:

• When accessing the GXP2130/2140/2160/2170/2135 for the first time or after a factory reset, users will be asked to change the default administrator password before accessing the GXP21xx Web interface.
• The new password field is case sensitive with a maximum length of 25 characters. Using a strong password including letters, digits, and special characters is recommended for better security.
• Since end-user level access is disabled by default, administrators will have to enable user web access under Maintenance 🡪 Web Access and set a new user password on the same page to enable users to access the Web UI.

• When changing any settings, always SUBMIT them by pressing the “Save” or “Save and Apply” button at the bottom of the page. If the change is saved but not applied, after making all the changes, click on the “APPLY” button at the top of the page to submit. After submitting the changes in all the Web GUI pages, reboot the phone to have the changes take effect if necessary (All the options under the “Accounts” page and “Phonebook” page do not require reboot. Most of the options under the “Settings” page do not require reboot).

Characters Input

The GXP21xx keypad can be used by tapping on an input field. GXP21xx keypad has 4 modes “123”, “ABC”, “abc”, and “1Bc”. Default mode is “1Bc”. Note: If the input field accepts only digits, only “123” mode will be available.

• “123” Mode: This mode allows you to enter digits and . only.
  
• “ABC” Mode: This mode allows to enter capital letters, digits, and symbolic characters.
  
• “abc” Mode: This mode allows to enter small letters, digits, and symbolic characters.
  
• “1Bc” Mode: This mode allows to enter capital letters, small letters, digits, and symbolic characters.
  

The following table describes allowed characters for each key.

Making Phone Calls

Handset, Speaker, and Headset Mode

The GXP2130/GXP2140/GXP2160/GXP2170/GXP2135 allows users to switch among handset, speaker, or headset when making calls. Press the Hook Switch to switch to the handset; press the Headset button to switch to the headset; or press the Speaker button to switch to the speaker.

Multiple SIP Accounts and Lines

GXP2160/GXP2170 can support up to 6 independent SIP accounts; GXP2140 can support up to 4 independent SIP accounts; GXP2130 can support up to 3 independent SIP accounts. Each account is capable of independent SIP server, user, and NAT settings. Each of the line buttons is “virtually” mapped to an individual SIP account. In off-hook state, select an idle line, and the dial tone will be heard. 

To make a call, select the line you wish to use. The corresponding LINE LED will light up in green. The user can switch lines before dialing any number by pressing the LINE buttons.

For example: If 2 independent accounts are registered on GXP2130 / GXP2140 / GXP2160 / GXP2170/GXP2135, when LINE 1 is pressed, the LINE 1 LED will light up in green. If LINE 2 is pressed, the LINE 2 LED will light up in green, and the subsequent call will be made through SIP account 2.

Incoming calls to a specific account will attempt to use its corresponding LINE if it is not in use. When the “virtually” mapped line is in use, the phone will flash the other available LINE in red. A line is ACTIVE when it is in use and the corresponding LED is red.

Completing Calls

There are several ways to complete a call.

• On hook dialing. Enter the number when the phone is on hook and then send out.
• When the phone is in idle, enter the number to be dialed.
• Take the handset off the hook, or press the Speaker button, or press the Headset button with the headset plugged in, or select an available LINE key.
• The call will be dialed out.
• Off hook and dial. Off-hook the phone, enter the number, and send out.
  • Take the handset off hook; or

• Predictive dialing. When dialing numbers, based on the entered digit or digits, the phone will predict and list the candidates of the target number.

If the target number is already saved in the phonebook, when you enter the first several digits, the phone will display a list of the matched numbers. If the target number appears on the list, the user could select the number by the Up/Down key and dial out. GXP2130/GXP2140/GXP2160/GXP2170/GXP2135 has a predefined call feature code (the first digit is *). When the user enters * as the first digit of the target number, the phone will list all feature codes as candidates.

• Redial. Redial the last dialed number.
  • Take the handset off the hook, or

• For Paging/Intercom, if the SIP Server/PBX supports the feature and has the Paging/Intercom feature code set up already, users do not necessarily need to toggle to paging mode in the call screen. Simply dial the feature code with the extension as a normal call.
• Users can enable the PTT (Push-To-Talk) feature, which allows them to initiate a 2-way intercom or paging with other parties by long pressing on an Intercom VPK to start the call and releasing the key to end the call. This feature can be found on Web GUI🡪Settings🡪Programmable Keys🡪Virtual Multi-Purpose Keys Settings.
• When dialing out via paging, the user can see that the “call-info” header contains “answer-after=0” and the “alert-info” header contains “info=alert-autoanswer;delay=0” in the outgoing INVITE.
• During an active call, the user can see call info on the LCD: shows the call lasting time; shows contact information if the number is already saved in the phonebook. When dialing DTMF, the user can press the round OK button to switch to the call info page.
• It is possible to mute the call at the dialing stage by composing a number, dialing the call, and pressing the mute button before the call is answered.

Making Calls Using IP Addresses

Direct IP Call allows two phones to talk to each other in an ad-hoc fashion without a SIP proxy. VoIP calls can be made between two phones if:

• Both phones have public IP addresses; or
  
• Both phones are on the same LAN/VPN using private or public IP addresses; or
  
• Both phones can be connected through a router using public or private IP addresses (with necessary port forwarding or DMZ).
  

To make a direct IP call, please follow the steps below:

• When the phone is in the idle state, press any number key or * key to bring up the “Onhook Dialing” page.
  
• Press the round menu key or the “DirectIP” softkey.
  
• Input the target IP address (Please see example below);
  
• Press the “OK” softkey to dial.
  

For example:

If the target IP address is 192.168.1.60 and the port is 5062 (i.e., 192.168.1.60:5062), input the following: 192*168*1*60#5062. The * key represents the dot (.), the # key represents the colon (:). Wait for about 4 seconds, and the phone will initiate the call.

Quick IP Call Mode:

The GXP2130/GXP2140/GXP2160/GXP2170/GXP2135 also supports Quick IP Call mode. This enables the phone to make direct IP calls using only the last few digits (last octet) of the target phone’s IP address. This is possible only if both phones are under the same LAN/VPN. This simulates a PBX function using the CSMA/CD without a SIP server. Controlled static IP usage is recommended.

To enable Quick IP Call Mode, go to the phone’s Web GUI → Settings → Call Features, set “Use Quick IP Call Mode” to “Yes”. Clicking on “Save and Apply” at the bottom of the Web GUI page to take the change. To make a Quick IP Call, take the phone off the hook first. Then dial #xxx where x is 0-9 and xxx<255. Press # or SEND and a direct IP call to aaa.bbb.ccc.XXX will be completed. “aaa.bbb.ccc” is from the local IP address, regardless of subnet mask. The numbers #xx or #x are also valid. The leading 0 is not required (but it’s OK).

For example:

• 192.168.0.2 calling 192.168.0.3 — dial #3 followed by # or “SEND”;
  
• 192.168.0.2 calling 192.168.0.23 — dial #23 followed by # “SEND”;
  
• 192.168.0.2 calling 192.168.0.123 — dial #123 followed by # “SEND”;
  
• 192.168.0.2: dial #3 and #03 and #003 results in the same call — call 192.168.0.3.
  

Note:

• The # will represent colon “:” in a direct IP call rather than the SEND key as in a normal phone call;
• If you have a SIP server configured, a direct IP call still works. If you are using STUN, a direct IP call will also use STUN.
• Configure the “User Random Port” to “No” when completing direct IP calls.

Making Calls Using Hostname/SIP URI

The GXP21xx series supports peer-to-peer calling using hostnames or SIP URIs, allowing users to dial contacts directly via domain names or SIP addresses. This feature eliminates the need to rely on static IP addresses, making it ideal for environments where IP addresses change frequently or where DNS resolution is preferred.

Configuration:

1. Adding Hostnames/SIP URIs to Contacts:
   • Navigate to Phonebook → Contacts in the web UI or LCD menu.
   • Add the hostname or SIP URI in the Work, Home, or Mobile field.
   • Save the contact.
2. Dialing via Hostname/SIP URI:
   • Select the contact with the hostname or SIP URI from the phonebook.
   • Initiate the call. The phone will resolve the domain name to an IP address and establish the connection.

Virtual Multi-Purpose Keys

Web UI Configuration

Users can find the Virtual Multi-Purpose Keys (VPK) configuration under the phone’s web UI → Settings → Programmable Keys → Virtual Multi-Purpose Keys tab. It is recommended to select “Reset” on this page before configuring VPK here. By default, all fixed VPKs are listed.

Click on “Edit VPK” for the line (fixed VPK) you would like to configure. A new window will pop up for VPK configuration. Users can configure Mode, Account, Description, and Value for the VPK.

If the VPK Description is set, it will show the description on the LCD screen. If the Description is left empty, the Default value will be the Account name.

Up to 38 mode options can be selected for the VPK. Once done, press “Save” on this window and press “Save VPK” at the bottom of the Virtual Multi-Purpose Keys page again to apply the change.

If users would like to configure more VPKs than the ones displayed on the page, users can click on “Add VPK” to configure a dynamic VPK. The dynamic VPK supports up to 28 mode options.

Please note:

1. Dynamic VPK does not support LINE and Shared LINE mode. These two mode options are only available for fixed VPKs.
   
2. Dynamic VPK does not support the NONE mode. If users do not need this VPK, click on “Edit VPK” for it and select “Delete” to remove this VPK.
   
3. All settings require the user to click on “Save” on the prompted window and the “Save VPK” button at the bottom of the Virtual Multi-Purpose Keys page to take effect.
   

P-Value for VPK Mode in String Format

GXP21xx P-Values for VPK Modes

The string could be capital or lowercase letters, but there must be no “space” in between. For example, in the cfg.xml, “Transfer” or “transfer” is the same as “18”, it will configure Virtual Multi-Purpose Key 3 as transfer mode.

LCD Indication and Configuration

The configured fixed VPKs are displayed next to the corresponding line. If dynamic VPKs are configured, the users can see a page number shown in the upper left corner of the LCD.

The following figures show page 1 and page 2 of the VPKs on the LCD. Pressing the “RIGHT” arrow key or “Next” softkey will switch to the next page; pressing the “LEFT” arrow key will switch back to the previous page.

The users could also edit and add VPK from the LCD.

1. To edit (fixed) VPK, press and hold the line key for about 4 seconds; a configuration window will pop up for the user to configure.
   
2. To add (dynamic) VPK, press and hold the RIGHT arrow key for about 4 seconds; a configuration window will pop up for the user to configure.
   

Up to 20 modes can be supported on fixed VPK, and up to 29 modes can be supported on dynamic VPK. Each mode is indicated by a different icon on the LCD, and the icon will be different when in a different status.

Please find the icon indications below for different modes of VPK.

GXP21xx VPK Modes

Please note that no matter how each line is configured on the idle screen, all the lines in the call screen will keep the line or shared line displayed for the corresponding accounts. For example, even if the user has configured all lines as VPK (with non-LINE mode), he/she can still use the configured account to dial out by Offhook or pressing SPEAKER, HEADSET, or any other unconfigured LINE key to go to the call screen.

When the user is in the call screen (during a call), he/she can press softkey to switch back to VPK screen.

When the user is in the VPK screen during a call, he/she can press the softkey or the corresponding line key to switch back to the call screen.
