MAKING CALLS USING IP ADDRESSES
Direct IP Call a llo ws t wo p hones to talk to e ach ot her in an ad-h oc f ashion withou t a SI P 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 conn ected throu gh a router us ing pub lic or privat e IP addresses (with necess ary
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 1 92.168.1 .60 and the p ort is 50 62 ( i.e., 192.16 8.1.60: 5062) , in put th e fol lowin g:
192*168*1*60#5062. The * key represents the d ot (.), the # key represents colon (:). Wait for about 4
seconds and the phone will initiate the call.
Quick IP Call Mode:
The GXP2120/GXP2110/GXP2100/GXP1450 a lso supports Quick IP Call mode. T his enables the phone
to make direct I P calls using only the last few digits (l ast 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
CMSA/CD without a SIP server. Controlled static IP usage is recommended.
To enable Quick IP Call Mode, go to phone's Web GUI->Advanc ed Setting page, set "Use Q uick IP Call
Mode" to "Yes ". C lic k on "U pdate" on the bottom of the W eb G UI page to take the c hange . To make Quick
IP Call, take the phone off hook f irst. T hen dial #xxx where x is 0-9 and x xx<25 5. Pr ess # or SEND an d a
direct IP call to aaa. bbb.c cc.X XX will be com pleted. "aaa. bbb.cc c" is from the loc al IP addres s re gard less
of subnet mask. The number #xx or #x are also valid. The leading 0 is not required (but it's OK).

SHARED CALL APPEARANCE (SCA)
The GXP2120/GXP2110/GXP2100/GXP1450 phone supports shared call appearance by Broadsoft

monitoring (idle, ac tive, progressing, hold) of the s hared line. W hen there is an incoming call d esignated
for the SCA group, all of the mem bers of the group will be notifie d of an incom ing call and will be able to
answer the call from the phone with the SCA extension registered.
All the users that belong to the s ame SCA group will be notified by visual indicator when a user s ei zes t he
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 cal l is pl aced on hold (with the excepti on 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
FIRMWARE VERSION 1.0.4.23 GXP2120/GXP2110/GXP2100/GXP1450 USER MANUAL Page 29 of 69

In addition, they would need to na vigate to “Settings”->”Basic Settings” on the web UI and set th e line to
"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.

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:

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 (under Advanced Settings page)
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".

UPGRADING AND PROVISIONING
The GXP2120/GXP2110/GXP2100/GXP1450 can be upgraded via TFTP/HTTP/HTTPS by configuring the
URL/IP Address for the TFT P/HTTP/HTTPS server and select ing a download method. Conf igure a valid
URL for TFTP or HTTP; the server name can be FQDN or IP address.
Examples of valid URLs:
firmware.grandstream.com
fw.ipvideotalk.com/gs
There are two ways to setup a software upgrade server: The IVR Menu or the Web Configuration Interface.
UPGRADE VIA KEY PAD MENU
Follow the steps below to configure the upgrade server path via phone's keypad menu:
• Press MENU button and navigate using Up/Down arrow to select Config;
• In the Config options, select Upgrade;
• Enter the firmware server path and select upgrade method. The s erver path could be in IP address
format or FQDN format;
• Press the "OK" softkey. A reboot message window will be prompt;
• Reboot the phone to have the change take effect.
When upgrading starts, the screen will show upgrading progress. When done you will see the phone
restarts again. Please do not interrupt or power cycle the phone when the upgrading process is on.
UPGRAGE VIA WEB GUI
Open a web browser on PC and enter the IP addres s of the phone. Then, login with the administrator
username and password. Go to Settings->Ad vance d Settings page, enter the IP address or the FQDN for
the upgrade server in "Firmware Server Path" field and choose to upgrade via T FTP or HTTP/HTTPS.
Update the change by clicking the "Update" button. Then "Reboot" or power cycle the phone to update the

Firmware upgrades take ar ound 60 seconds in a controlled LAN or 5-10 minutes over th e Internet. We
recommend completing firmware upgrades in a controlled LAN environment whenever possible.
NO LOCAL TFTP/HTTP SERVERS
For users that would like to use remote upgrading without a local TFTP/HTTP server, Grandstream offers a
NAT-friendly HTTP server. This enables users to download the latest software upgrades for their phone via
this server. Please refer to the webpage:
http://www.grandstream.com/support/firmware.
Alternatively, users can download a f ree TFTP or HT TP server and c onduct a loc al firmware upgrad e. A
free windows version TFTP server is available for download from :
1. Unzip the firmware files and put all of them in the root directory of the TFTP server;
2. Connect the PC running the TFTP server and the phone to the same LAN segment;
3. Launch the TFTP server and go t o the File menu->Configure->Securit y to change the TFTP s erver'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
Microsoft IIS web server.
Note:
When the phone boots up, it will send a TFTP or HTTP request to download the configuration file
"cfgxxxxxxxxxxxx" where "xxxxxxxxxxxx" is the MAC address of the phone. If it is a normal TFTP or HTTP
upgrade, the following messages “TFTP Error from [IP ADRESS] requesting cfg000b82023dd4 : File does
not exist. Configuration File Download” can be ignored in the TFTP/HTTP server log.
http://httpd.apache.org/ or use

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->Settings->Advanced Settings.
For a detailed parameter list, please refer to the corresponding firmware release configuration template.
When the GXP2xx/GXP1450 boots up or rebo ots, it wil l iss ue a req uest to do wnload a co nfigur atio n XML
file named "cfgxxxxxxxxxxxx.xml" followed by a file named "cfgxxxxxxxxxxxx", where "xxxxxxxxxxxx" is
the MAC address of the phone, i.e., "cfg000b8 20102ab.xm l" and "cfg000b82010 2ab". If the d ownload of
"cfgxxxxxxxxxxxx.xml" file is not successful, the provision program will download a generic cfg.xml file. The
configuration file name should be in lower case letters.
