Hi Everyone! Im currently on the start of using Asterisk as a pstn gateway with SER. I have been searching google for about two hours now with not much success. There are probably alot of experts around here who could give something to start with. Could somebody kindly give me a basic idea how I can do about implementing this. Does Asterisk register itself as a client with SER? Also how does SER know that the number being dialed is suppose to be sent to Asterisk? Also I plan to place the Asterisk PSTN GW on a public network, would this be advisable?
