Dial Key" to "No" from Web GUI->Account page.
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:
• Take handset off hook. You shall hear dial tone from the handset;
• Press *** to enter the GXP1100/GXP1105 IVR menu;
• Enter 47 for Direct IP Call. After hearing "Direct IP Calling", the dial tone will be heard again;
• Enter the target IP address to dial (Please see example below).
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 GXP1100/GXP1105 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.
