Hi,
A PSTN Gateway is a device in which you will find two parts: an ip interface and a POTS one(FXS / FXO). First of all, you'll find a VoIP protocol processor in it to interact with the IP network and a PSTN one that will do the job on this side. Finally, the gateway is responsible to convert VoIP stuff to PSTN and vice-versa. There is no magic, your device must be plugged in a phone line or PBX in order to get service from the PSTN. The same rule apply to VoIP. Hope this helped, Kevin. > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:sip-implementors- > [EMAIL PROTECTED] On Behalf Of Phillip Brisco > Sent: 18 mai, 2004 18:29 > To: [EMAIL PROTECTED] > Subject: [Sip-implementors] PSTN gateways > > Hi, > I don't quite understand how a PSTN gateway connects to the > PSTN.
