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, then 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:
