Direct IP calls
Direct IP calling allows two phones 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 access the voice menu prompt by dial “***” or press the button on the HT286, and dials
“47” to access the direct IP call menu. User will hear a voice prompt “Direct IP Calling” and a dial
tone. Enter a 12-digit target IP address to make a call.
