I don't run in to many telecom folks these days. Are you still working in the industry? I used to do a lot of telecom consulting for a large customer who we transitioned to a 100% SIP carrier. This particular carrier used AdTran TA 900 series gateways to provide T1-CAS/PRI to older phone switches. The project was particularly interesting because the carrier let me (a third-party analyst) have unheard of access to their infrastructure. Once I earned their trust, I had access to all of the AdTran devices, as well as their core switching and CDR reporting tools. I actually just put wraps on a Ruby script that I use to analyze call concurrency from CDR exports (from CDRTool [1]). I dropped it in a Gist if you're interested. It takes a CDRTool query export (CSV data) and outputs a tab-delimited concurrency datafile that can be used pretty easily with gnuplot. The script could be easily adapted to any CDR report that uses single-line call entries. https://gist.github.com/1706903 https://gist.github.com/1706903 1 - http://www.ag-projects.com/CDRTool.html http://www.ag-projects.com/CDRTool.html PS - If you find this at all interesting, hit me up on Twitter to keep in touch https://twitter.com/#!/bradleyland https://twitter.com/#!/bradleyland
