4.2.2 Direct IP calls

Direct IP calling allows 2 phones, that is, a HandyTone with a 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 other VOIP Device(i.e., another HandyTone ATA or other
HandyTone ATA) have public IP addresses, or
both HandyTone ATA and other VOIP Device(i.e., another HandyTone ATA or other
HandyTone ATA) are on a same LAN using private or public IP addresses, or
both HandyTone ATA and other VOIP Device(i.e., another HandyTone ATA or other
HandyTone ATA) can be connected through a router using public or private IP
addresses.
To make a direct IP calling, 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. If there is a user part, again follow Section 4.1 with voice prompt
47, and then the encoded user part, followed by *3 (encoding for "@") and then
followed by the 12-digit target IP address. Destination ports can also be specified using
*4 (encoding for ":") followed by the encoded port number.
The follow is a table of the encoding scheme for the most commonly used characters:
