[swinog] ISP service management tool

hi all, I'm looking for an open-source tool for ISP service management. It should allow documenting of all the physical network (ideally, also the datacenter environment), and associate physical and logical network instances with customer services and their contracts. I looked at several tools, but they all are designed for Enterprise IT tasks, and none of them deals with subscribers and contracts: http://www.opendcim.org/ http://www.i-doit.org/ The NOC project seems to be promising, I should probably invest more time in learning it: http://kb.nocproject.org/display/SITE/NOC Your feedback will be appreciated. Commercial systems would also be OK, as long as they fit the requirements and have open API. thanks, stan
