SMDR/CDR daemon/processor

I was asked the other day to build a Station Message Detail Recording (SMDR) or Call Detail Record (CDR) processor for a client. I started searching for examples of such a thing. I mostly found commercial apps to handle the job. I could not find anything on Hotscripts, phpGround.com, and a few others. I did find a few Open Source things on Source Forge. http://sourceforge.net/projects/simplesmdr/ It is active, but has missing files... References /home/administrator/* Those were not included though... http://sourceforge.net/projects/opensmdr/ Written in PHP, but it hasn't been touched since 2004. http://sourceforge.net/projects/astbilling/ Haven't had a chance to look at it yet. My question: has anybody worked with any type of project that involved capturing/parsing/storing/regurgitating such information? also, have you ever worked with this or similar devices? http://www.precidia.com/products/ipocket_232.html TIA!
