5.2 Make Phone Calls
5.2.1 Calling phone or extension numbers
To make a phone or extension number call:
a) Dial the number directly and wait for 4 seconds (default “No Key Entry Timeout”). Or
b) Dial the number 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, and call-forward.
5.2.2 Direct IP calls
Direct IP calling allows two phones, 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. VoIP calls can be made between
two phones if:
• Both HandyTone ATA and the other VoIP device (i.e., another HandyTone ATA or other SIP
products) have public IP addresses, or
• Both HandyTone ATA and the other VoIP device (i.e., another HandyTone ATA or other SIP
produces) are on the same LAN using private or public IP addresses, or
• Both HandyTone ATA and the other VoIP device (i.e., another HandyTone ATA or other SIP
products) can be connected through a router using public or private IP addresses.
To make a direct IP call, first pick up the analog phone or turn on the speakerphone on the analog
phone, follow Section 5.1 with voice prompt 47, followed by the 12-digit target IP address. Destination
ports can be specified by using “*4” (encoding for “:”) followed by the encoded port number.
Following is a table of the encoding scheme for the most commonly used characters:
