USING THE GXP2120/GXP2110/GXP2100/GXP14xx

GETTING FAMILAR WITH THE LCD
GXP2120/GXP2110/GXP2100/GXP14xx has a dynamic and customizable screen. The screen displays differently depending on whether the phone is idle or in use (active). The following table describes the items displayed on the GXP2120/GXP2110/GXP2100/GXP14xx idle screen.

GETTING FAMILAR WITH THE KEYPAD

The following table describes the buttons used on the GXP2120/GXP2110/GXP2100/GXP14xx keypad.

MAKING PHONE CALLS

HANDSET, SPEAKER AND HEADSET MODE
The GXP2120/GXP2110/GXP2100/GXP14xx allows users to switch among handset, speaker or headset when making calls. Press the Hook Switch to switch to handset; press the Headset button to switch to headset; or press the Speaker button <)) to switch to speaker.

MULTIPLE SIP ACCOUNTS AND LINES
GXP2120 can support up to 6 independent SIP accounts; GXP2110/GXP2100 can support up to 4 independent SIP accounts; GXP14xx can support up to 2 independent 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 GXP2120/GXP2110/GXP2100/GXP14xx, 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 out;

•  Take handset off hook; or
  Press Speaker button; or
  Press Headset button with 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 handset off hook; or
  Press Speaker button; or
  Press Headset button with headset plugged in; or
  Press an available LINE key to activate speaker;

• You shall hear dial tone after off hook;

• Enter the number;

• Press SEND key or # to dial out.

Redial. Redial the last dialed number.

• Take handset off hook; or
  Press Speaker button; or
  Press Headset button with headset plugged in; or Press an available LINE key to activate speaker; or When the phone is in idle;

• Press SEND button to dial the selected contact.

Speed Dial. Dial the number configured as Speed Dial on Line Key.

• Go to phone’s Web GUI->Settings->Programmable Keys, configure the Line Key’s Key Mode as Speed Dial. Select the account to dial from, enter the Name and User ID (the number to be dialed out) for the Line Key. Click on “Save and Apply” at the bottom of the Web GUI page;
• Off hook the phone, or directly press the Speed Dial key to dial out.

Call Return. Dial the last answered call.

• Go to phone’s Web GUI->Settings->Programmable Keys, configure the Line Key’s Key Mode as Call Return. Select the account to dial from, no Name or User ID has to be set on for Call Return;
• Off hook the phone, or directly press the Call Return key to dial out.

Via Paging/Intercom.

• Take handset off hook; or
  Press Speaker button; or
  Press Headset button with headset plugged in; or
  Press an available LINE key to activate speaker;

• You shall hear dial tone after off hook;

• Press MENU button to switch the call screen from “Dialing” to “Paging”;

• Enter the number;

• Press SEND key or # to dial out.

Note:

• After entering the number, the phone waits for the No Key Entry Timeout (Default timeout is 4 seconds, configurable via Web GUI) before dialing out. Press SEND or # key to override the No Key Entry Timeout;
• If digits have been entered after handset is off hook, the SEND key will works as SEND instead of REDIAL;
• By default, # can be used as SEND to dial the number out. Users could disable it by setting “User # as Dial Key” to “No” from Web GUI->Account X->Call Settings;
• For Paging/Intercom, if the SIP Server/PBX supports the feature and has Paging/Intercom feature code set up already, users do not necessarily need toggle to paging mode in the call screen. Simply dial the feature code with extension as a normal call.
• When dial out via paging, user can see the “call-info” header contains “answer-after=0” and “the “alert-info” header contains “info=alert-autoanswer;delay=0” in the outgoing INVITE.

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:

• Press MENU button to bring up main menu;
• Select “Direct IP Call” using the navigation arrow keys;
• Press MENU to enter the Direct IP Call mode;
• Input the 12-digit target IP address (Please see example below);
• Press the “More” softkey to make sure the softkey selection “IPv4” or “IPv6” is correctly selected depending on your network environment;
• Press “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: 192168160#5062. The key represents the dot (.), the # key represents colon (:). Wait for about 4 seconds and the phone will initiate the call.

Quick IP Call Mode:
The GXP2120/GXP2110/GXP2100/GXP14xx 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 phone’s Web GUI->Settings->Call Features, set “Use Quick IP Call Mode” to “Yes”. Click on “Save and Apply” on the bottom of Web GUI page to take the change. To make Quick IP Call, take the phone off 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 number #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 direct IP call rather than SEND key as in normal phone call;
• If you have a SIP server configured, direct IP call still works. If you are using STUN, direct IP call will also use STUN;
• Configure the “User Random Port” to “No” when completing direct IP calls.

ANSWERING PHONE CALLS

RECEIVING CALLS

An IVR will prompt the user through the process of message retrieval.

SHARED CALL APPEARANCE (SCA)
The GXP2120/GXP2110/GXP2100/GXP14xx phone supports shared call appearance by Broadsoft standard. This feature allows members of the SCA group to shared SIP lines and provides status monitoring (idle, active, progressing, hold) of the shared line. When there is an incoming call designated for the SCA group, all of the members of the group will be notified of an incoming call and will be able to answer the call from the phone with the SCA extension registered.

All the users that belong to the same SCA group will be notified by visual indicator when a user seizes the line and places an outgoing call, and all the users of this group will not be able to seize the line until the line goes back to an idle state or when the call is placed on hold (with the exception of when multiple call appearances are enabled on the server side).

In the middle of the conversation, there are two types of hold: Public Hold and Private Hold. When a member of the group places the call on public hold, the other users of the SCA group will be notified of this by the red-flashing button and they will be able to resume the call from their phone by pressing the line button. However, if this call is placed on private-hold, no other member of the SCA group will be able to resume that call.
To enable shared call appearance, the user would need to register the shared line account on the phone. In addition, they would need to navigate to “Settings”->”Programmable Keys” on the web UI and set the line key mode as “Shared Line”. If the user requires more shared call appearances, the user can configure multiple line buttons to be “shared line” buttons associated with the account.

INSERTING PAUSE INTO SPEED DIALS AND PHONEBOOK ENTRIES
GXP2120/GXP2110/GXP2100/GXP14xx supports to insert pause into speed dials and phonebook entries. There are two types of pause: soft pause and hard pause.

Soft pause:
Insert “,” into a speed dial number or phonebook number. Please see Figure 6 and Figure 7 for the configurations of inserting soft pause for speed dial and phonebook entry, correspondingly.

For example, the destination number is “2001,1”. When dial out, “2001”, the number before comma, will be sent as the caller number first. After the call established, phone will wait 1 second and dial “1”, the number after comma, as DTMF automatically.

Programable Key

Hard pause:
Insert “;” into a phone number to represent hard pause. The configuration of inserting hard pause is similar to that of soft pause.

For example, number “2003;1” is configured in aspeed dial or phonebook entry. When the item is dialed, “2003” will be sent as the caller number first. After the call is established, user needs to press DTMF softkey manually to send “1” as DTMF.

CONFIGURATION VIA WEB BROWSER
The GXP2120/GXP2110/GXP2100/GXP14xx 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 Microsoft’s IE, Mozilla Firefox and Google Chrome.

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 on the LCD or go to MENU->Status->Network Status;
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.

Note:

• The computer has to 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 connected to. In 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 IP address 192.168.40.154, please enter “http://192.168.40.154” in the address bar of the browser;
• There are two default passwords for the login page:

The password is case sensitive with maximum length of 25 characters.

•  When changing any settings, always SUBMIT them by pressing the “Save” or “Save and Apply” button on the bottom of the page. If the chaange is saved only but not applied, after making all the changes, click on the “APPLY” button on 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 “Accounts” page and “Phonebook” page do not require reboot. Most of the options under “Settings” page do not require reboot).

DEFINITIONS
This section describes the options in the phone’s Web GUI. As mentioned, you can log in as an administrator or an end user.

• Status : Displays the Account status, Network status, and System Info of the phone;
• Account : To configure the SIP account;
• Network : To configure network settings;

STATUS PAGE DEFINITIONS

NAT SETTINGS

If the devices are kept within a private network behind a firewall, we recommend using STUN Server. The following settings are useful in the STUN Server scenario:

• STUN Server
  Under Settings->General Settings, enter a STUN Server IP (or FQDN) that you may have, or look up a free public STUN Server on the
  internet and enter it on this field. If using Public IP, keep this field blank.

• Use Random Ports
  It is under Settings->General Settings. This setting depends on your network settings. When set to “Yes”, it will force random generation of
  both the local SIP and RTP ports. This is usually necessary when multiple GXPs are behind the same NAT. If using a Public IP address, set this parameter to “No”.

• NAT Traversal
  It is under Accounts X->Network Settings. Default setting is “No”. Enable the device to use NAT traversal when it is behind firewall on a private
  network. Select Keep-Alive, Auto, STUN (with STUN server path configured too) or other option according to the network setting.

WEATHER UPDATE
To customize GXP2120/GXP2110/GXP2100/GXP14xx to display weather information for the preferred city, users could go to web GUI->Settings->Web Service page and enter the city code in the following options:

By default the City Code is set to “Automatic”, which allows the phone to obtain weather information based on the IP location detected. To use “Self- Defined City Code” option, please follow the steps below to obtain the correct city code:

• In a web browser, go to www.weather.com;
• Enter the city name in the search field. For example, Boston, MA. And click on “SEARCH”;
• The searching result will show in a new window with URL in the browser’s address bar. For example, http://www.weather.com/weather/right-now/Boston+MA+USMA0046
• In the above link, USMA0046 is the city code to be filled in “Self-Defined City Code” option.

Users could then further configure the “Update Interval” and “Degree Unit” for weather information display.

MULTICAST PAGING
GXP21xx/14xx supports multicast paging, including sending and listening. On the phone, users could send multicast page by setting the multicast address and port. Also, users can listen to at most 10 different multicast IP address.

Send Multicast Paging
Multicast sender related settings are under Web UI, Settings -> Programmable keys. Select Multicast paging as the key mode for dial page call. Multicast paging listening related settings are under Web UI Settings -> Multicast Paging.

Sender multicast page configurations are under phone’s Web UI Settings->Programmable Keys->Line Keys OR Multi-Purpose Keys.

1. Set the key Mode to Multicast Paging in dropdown list.
2. Enter the multicast paging description in Description field.
3. Enter multicast paging address and port in Value field.
   The range of multicast page address is 224.0.0.0 to 239.255.255.255 with a port not in use by phone.

The Figure 6 and Figure 7 show the example of setting Line Keys/MPK to multicast page sending key.

GXP21xx/GXP14xx supports 5 codecs for Multicast Paging. User can specify the multicast page sending codec under Web UI Settings ->Multicast Paging->Multicast Paging Codec. The supported codecs are PCMU, G.729A/B, PCMA, G.726-32, G.723, iLBC and G.722.
After configuring the sender multicast page, users could make a multicast page to remote parties.

1. Press the configured MPK or Line Key to send a multicast page.
   The LED light of the key will turn green and the phone screen will show the multicast address with defined label.

2. Press the “EndCall” soft key to end the multicast paging.

Receive Multicast Paging

To receive multicast page, GXP21xx/GXP14xx must be well configured to listen to the right address and port. The configurations are under Settings->Multicast Paging. There are 10 listening address supported with priority levels 1 to 10. Optionally, each of these addresses can also have a label that will display on LCD when the page is received.

Note: The multicast page configuration requires rebooting to take effect.

Paging Barge
This option is to control the priorities between multicast page and common SIP call. Available options are Disabled and numbers 1 to 10. If the option is set to disabled then all incoming pages are ignored while in call.
When the option is set to number, Paging Barge is enabled. If the number of Paging Barge is higher than an incoming page’s priority value (determined by the position in the list 1-10) then the incoming page is not played. Similarly, if the Paging Barge value is lower than an incoming page’s priority value, and then the active SIP call will be held.

As an example, in Figure 8, the Paging Barge is configured as 3. During an active call if incoming multicast page priority is greater or equal to 3, the current active call will be held, and page will be played. However, if the incoming multicast page priority is 1 or 2, the current active call will be kept.

Paging Priority Active
This option is to control the priorities among different multicast pages. If the option is disabled, the phone ignores any incoming pages when a page is already being played. Otherwise, incoming pages with a higher priority will be played instead of the current page. For example, if the phone is playing a page whose priority is 5 and there is an incoming page with priority 3, the priority 5 page will stop and the priority 3 page will play instead.
After multicast page listening well configured, please reboot the phone to let the settings take effect. When there is a page on the listening address and port, the phone will play the incoming audio automatically.

User can press “EndCall” softkey to end the page.

PUBLIC MODE
The GXP2120/GXP2110/GXP2100/GXP14xx supports hot desking using public mode. Under public mode, users could login the phone with the SIP account User ID and password. Please follow the steps below to configure the phone for public mode:

• Fill up the SIP server address for account 1 first;
• Under Web GUI->Settings->General Settings, set “Public Mode” option to “Yes”. Click “Save and Apply” and reboot the phone;
• When the phone boots up, SIP User ID and Password to register to the configured SIP server in account 1 will be required. Enter the correct account information to log in to the phone. When entering the account information, press softkey “123”/”abc” to toggle input method;
• In login page, pressing CONF button on the phone will show phone’s IP address;
• After using the phone, go to LCD MENU->LogOut to log off the public mode.

EDITING CONTACTS AND CLICK-TO-DIAL

2.  Connect the PC running the TFTP server and the phone to the same LAN segment;
3. Launch the TFTP server and go to the File menu->Configure->Security to change the TFTP server’s default setting from “Receive Only” to “Transmit Only” for the firmware upgrade;
4. Start the TFTP server and configure the TFTP server in the phone’s web configuration interface;
5.  Configure the Firmware Server Path to the IP address of the PC;
6. Update the changes and reboot the phone.

End users can also choose to download a free HTTP server from http://httpd.apache.org/ or use Microsoft IIS web server.

CONFIGURATION FILE DOWNLOAD

Grandstream SIP Devices can be configured via the Web Interface as well as via a Configuration File (binary or XML) through TFTP or HTTP/HTTPS. The “Config Server Path” is the TFTP or HTTP/HTTPS server path for the configuration file. It needs to be set to a valid URL, either in FQDN or IP address format. The “Config Server Path” can be the same or different from the “Firmware Server Path”.

A configuration parameter is associated with each particular field in the web configuration page. A parameter consists of a Capital letter P and 2 to 3 (Could be extended to 4 in the future) digit numeric numbers. i.e., P2 is associated with the “Admin Password” in the Web GUI->Maintenance->Web/Telnet Access page. For a detailed parameter list, please refer to the corresponding firmware release configuration template.

When GXP2120/GXP2110/GXP2100/GXP14xx boots up, it will send TFTP or HTTP/HTTPS requests to download configuration files, “cfg000b82xxxxxx” and“cfg000b82xxxxxx.xml”, where “000b82xxxxxx” is the MAC address of the phone. If the download of “cfgxxxxxxxxxxxx.xml” is not successful, phone will issue request for a generic configuration file “cfg.xml”. Configuration file name should be in lower case letters.
