Abstract:
1. A computer-implemented method for analyzing locally routed phone calls, the method comprising: retrieving call routing information from a call data records (CDR) collector operable to collect call detail records from a plurality of network elements in a network, wherein the call routing information indicates how a plurality of calls were terminated through the network; retrieving call setup costs associated with a plurality of calls from the CDR collector, wherein the CDR collector is further operable to attribute costs to the plurality of calls setup up across a network; retrieving local trunk groups from a local trunk group inventory; associating vendor types with calls identified in the call routing information; associating local trunk groups with calls identified in the call routing information; and based on the local trunk groups, the call setup costs and the vendor types, generating view of local calls setup through the network, wherein the view associates area code/local exchange numbers (NPA-NXX's) with information.
