Apologies if this is off-topic here, but this seemed like a good friendly place to ask. Apologies for being so naïve also... Question is, how can I get cdrtool to rate voip-to-voip calls when destination is non-numeric? As in, say, sip:holmes@example.com calls sip:watson@example.com. How do I get cdrtool to match *(a)example.com or *(a)example2.com? (FWIW, I'm just trying to see how this works... no plan of rolling out this Evil Scheme into a real world deployment.) While cdrtool has decent documentation, I wish this was a little more easy on me. Has anyone read/reviewed this book yet? http://www.packtpub.com/building-telephony-systems-with-openser/book I'm specifically interested in the "Billing with Freeradius and CDRTool" part. Thanks, Sajith. -- Don't you wish you had more energy... or less ambition? 9DB8FF06 : CB80 0BA6 7D13 B10A 6FBB D43E B4D2 28AD 9DB8 FF06
