5.2 Make Phone Calls

5.2.1 Calling phone or extension numbers

There are currently two methods to make an extension number call:

• Dial the numbers directly and wait for 4 (default) seconds. This default parameter

can be adjusted in the web configuration page.

• Dial the numbers directly, and press # (assuming that “use #” as dial key is

selected in web configuration).

Other functions available during the call are call-waiting/flash, call transfer (both blind

and consultant) and call forwarding, assume that an ITSP is used.

5.2.2 Direct IP calls

Direct IP calling allows two parties, that is, a HandyTone with an analog 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 HandyTone ATA and other VoIP Device(i.e., another HandyTone ATA or

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

• Both HandyTone ATA and other VoIP Device are on the same LAN using private

or public IP addresses, or

• Both HandyTone ATA 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 pick up the analog phone or turn on the

speakerphone on the analog phone, then follow Section 4.1 with voice prompt 47,

followed by the 12-digit target IP address. Destination ports can also be specified using
