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.
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:
1. Press MENU key to bring up main menu.
2. Select "Direct IP Call" using the navigation arrow keys.
3. Press MENU to enter the Direct IP Call mode.
4. Input the 12-digit target IP address (Please see example below).

FW version 1.0.4.152
18
5. Press the "More" softkey to make sure the softkey selection "IPv4" or "IPv6" is correctly selected
depending on your network environment.
6. 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: 192*168*1*60#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 GT210 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". Clicking 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 key 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 # or "SEND".
 192.168.0.2 calling 192.168.0.123 -- dial #123 followed by # or "SEND".
 192.168.0.2: dial #3 and #03 and #003 results in the same call -- call 192.168.0.3.
Notes:
 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 "Use Random Port" to "No" when completing direct IP calls. The option “Use
Random Port” is under phone’s Web GUISettings General Settings page.

FW version 1.0.4.152
