[Kamailio-Users] CDRTool

Hi All, Using CDRTool 6.7.1 with Kamailio 1.4.1, have the rating engine running now fine. Doing my accounting using Freeradius and the CDR's are showing up fine in CDRtool. I am starting to work on the rates and destinations etc.. One issue I may have, one of my providers makes me put *1001* in front of the number I am dialling and then the local code, not the international one.. How will I normalise this *1001* so that CDRTool will just read in the prefix? Also can anyone point me in the direction of good documentation for the rating engine? The rating.txt is a bit vague at best. TIA. Brian
