One familiar reliable term that really suits your wireless network demand is VOIP stands for Voice over Internet Protocol. It is also renowned as Internet Telephony or IP Telephony. One important part in VOIP connection is the gateway.

A VOIP PTSN gateway is an urgent device that links the VOIP network to your public telephone network. You will still be able to make and receive calls from your PTSN line, even if you use an internet protocol-based system. There are several different types of gateway. Some of them are equipped with interfaces of analog/digital so that they will be able to connect to your local telephone company. The other important feature is the ability of auto switching of incoming PTSN or VOIP calls.

There is a basic difference that you should know that VOIP is based on an IP address and PTSN has specific phone number. However, VOIP to PTSN is not impossible to be linked one to another, by the help of address translation in which IP address is transformed into the phone number, then, it is handed over to the PSTN network and vice versa.
