Voice over IP
VoIP (Voice over IP) is a voice service provided by the ISP or VSP (Voice Service
Provider). It compresses the voice signal into data package and transfers the data
through the IP network. That is, it is a telecommunications service of sounds by the
open Internet. With the Internet, it not only offers real-time sound service, but also it
can connect to anywhere in the world. It allows users to carry out remote
conversation without passing PSTN.

simply hook up your phone to the telephone adapter and create a service similar to
an additional phone line.

Hardware Connection for using VoIP
Below shows a brief hardware connection for executing VoIP function.
1. Connect a telephone handset (or fax machine) to the Phone1 port and
another telephone handset to Phone2 port (optional) on the wireless IAD
separately by using phone cables.
2. Use a phone cable to connect PSTN port on the wireless IAD to the Phone
port on the splitter.
3. Use a phone cable to connect DSL port on the wireless IAD to the Modem
port on the splitter.
4. Connect the telephone line from the wall outlet to the Line port of the splitter.
Note: Microfilter/splitters can be purchased separately. To use the VoIP service
without a microfilter/splitter connect the DSL port directly to the telephone wall
outlet. However, with this configuration you cannot use the RTA1046VW for PSTN
calls (conventional telephone service).
