Hi.i have a problem on transfering my inbound calls on fxo to a specific fxs port.i have connected my GW to pbx with one fxo line,so when i dial that spesific line number(on pbx) that is connected to my router after two beep router picks up the line and provides dial tone now i can dial my fxs port DN, but i want that when i call my GW it pick up and then automaticly transfer my call to a spesific fxs port,how is this possible.(i have tried incoming called-number X where X was one of my fxs numbers but it didnt work when i call my GW again it answers the line and provides dial tone for me but not transfering my call to specified fxs port number)
