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:
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 LXP100 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 CMSA/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 the Web GUI page to take the change. To
