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.
