Making a Call by Using an IP Address
Direct IP calls allow two phones to talk to each other in a special way without a SIP
proxy. VoIP calls can be made between two phones when:
z
Both phones have public IP addresses.
z
Both phones obtain the private or public IP addresses on the same LAN or VPN
network.
z
Both phones can be connected through a router by using public or private IP
addresses (with a valid port or DMZ).
All the necessary ports on the two phones must be enabled.
To make a direct IP call, do as follows:
Step 1
Press
MENU
to access the main menu.
Step 2
Select
Direct IP Cal
l by using the
UP
and
DOWN
keys.
Step 3
Press
MENU
to confirm.
Step 4
Type the destination IP address.
Step 5
Press the
OK
soft key to initiate a call.
For example, if the destination IP address is 10.10.10.1, type 10*10*10*1. The * key
represents the dot.
Quick IP Call Mode
Dial an IP address in the same LAN or VPN network by typing the last octet of the IP
address. This simulates a PBX function using the CMSA or CD without a SIP server. In
this mode, the controlled static IP address is recommended.
On the Advanced Settings page, set Use Quick IP-call Mode to Yes. When #xxx is
dialed (The range of x is 0–9 and xxx cannot be larger than 255.), a direct IP call is
initiated as aaa.bbb.ccc.XXX. aaa.bbb.ccc is the local IP address regardless of the
subnet mask. The numbers #xx or #x are also valid.
The following is an example.
z
0.10.10.2 calls 10.10.10.3 — dial #3, followed by SEND.
To call 10.10.10.3, 192.168.0.2 can dial #3; #03; or #003.
z
10.10.10.2 calls 10.10.10.23 –– dial #23, followed by SEND.
z
10.10.10.2 calls 10.10.10.123 –– dial #123, followed by SEND.
