4.3.3 Make Calls using IP Address

Direct IP calling allows two parties, that is, a BudgeTone phone and another VoIP
Device, to talk to each other in an ad hoc fashion without a SIP proxy. This kind of VoIP
calls can be made between two parties if:

• Both BudgeTone phone and other VoIP Device(i.e., another IP Phone or

BudgeTone SIP phone or other VoIP unit) have public IP addresses, or

• Both BudgeTone phone and other VoIP Device are on the same LAN using

private or public IP addresses, or

• Both BudgeTone phone and other VoIP Device can be connected through a router

using public or private IP addresses (with necessary port forwarding or DMZ).

To make a direct IP to IP call, first off hook, then press “MENU” key, then enter a 12-
digit target IP address to make the call. If port is not default 5060, destination ports can
be specified by using “*4” (encoding for “:”) followed by the port number.

Examples:

• If the target IP address is 192.168.0.10, the dialing convention is

MENU_key 192 168 000 010
followed by pressing the “SEND” key or wait for seconds in the No Key Entry
Timeout.

• If the target IP address/port is 192.168.1.20:5062, then the dialing convention

would be:
MENU_key 192168001020*45062
followed by pressing the “SEND” key wait for seconds in the No Key Entry
Timeout.
