Hi all: I want to create a billing system by using ser and radius. Is there any document about setting radiusclient with ser? The software are too old to used in document "SIP Express Router RADIUS HOWTO" in iptel.org. Now, I have already installed the radius server and ser & radiuseclient in two computers. The radius server seems to work well, but i am not sure wherter the radius server and radiusclient could be work besause of the difficult steps setting. If I could know more about the setup details that will be grate. Please give me a hand, thank you. Sincerely, Caxton .
