InterPhone-to-Phone Mode
With great interoperability, InterPhone is capable of connecting to PSTN, regular telephone
system, by transferring through other Internet Telephony products, such as DSG IP1000 and
IP2000 Gateway. With an active ITSP (Internet Telephony Service Provider)
Account or Device ID Number, you can call all the covered areas with ultra low rates. In this
mode, the receiver end does not need any InterPhone or VoIP device.
Note: IP1000, IP2000 are DSG VoIP Gateways connecting the Internet and PSTN (Public
Switched Telephone Network). A VoIP Gateway enables callers using Internet to talk to regu-
lar phone users without traditional telecommunication services.
Phone-to-InterPhone Mode
For regular phone users, you can also enjoy the savings! To call an InterPhone user, first you
dial to a local DSG IP2000 Internet Gateway. Once you are connected, simply dial the six-digit
Device ID Number with button prefix and you can talk to any worldwide InterPhone users!
Note: To use InterPhone-to-Phone Mode or Phone-to-InterPhone Mode, callers must sub-
scribe the services provided by DSG Internet Telephony Network from DSG compatible ITSPs.
