Direct IP Call
Direct IP calling allows two parties, that is, a handset and another VoIP device, to talk to each other in an ad
hoc fashion without a SIP proxy.
Elements necessary to complete a Direct IP Call:
• Both DP720 and other VoIP Device, have public IP addresses, or
• Both DP720 and other VoIP Device are on the same LAN using private IP addresses, or
• Both DP720 and other VoIP Device can be connected through a router using public or private IP
addresses (with necessary port forwarding or DMZ).
Users can perform IP calls using Star code following the below steps:
1. Pick up the handset and press Dial key .
2. Dial *47 followed by the target IP Address.
Note: You can enter directly *47 + target IP address, and then press the dial key to initiate the call.
Examples of direct IP calls
a) If the target IP address is 192.168.0.160, the dialing convention is *47 then 192*168*0*160, followed
by pressing the “#” key if it is configured as a send key or wait 4 seconds. In this case, the default
destination port 5060 is used if no port is specified.
