Telephony Ports

Your Internet Gate model is equipped with telephony ports, one FXO port and two FXS ports.

The LINE port (also referred to as FXO port) is a general one-line SIP/PSTN gateway. It can be connected to the global telephone network so you can integrate your existing PSTN telephone number to your VoIP system. It is also useful for fallback in case you temporarily loose the power or your Internet connection.

The PH ports (also referred to as FXS ports), i.e. the telephone ports, are general SIP clients. This means that the phone unit connected to the FXS port in effect becomes an IP phone. At least five ordinary phones can be connected.

The telephone port support is available without the SIP Switch software addition, but the SIP Switch increases the usefulness.
