Overview of Cisco Carrier Sensitive Routing
The Cisco Carrier Sensitive Routing (CSR) application provides end users with the capability to
manipulate the routing of calls from the gatekeeper based on the ingress carrier and the DNIS. The
routing can be based on QoS along with many other attributes pertaining to a carrier. With CSR, you can
provision data specific to carriers that pertain to your network to maximize cost, QoS, and carrier
relations. CSR can run on a Sun/Solaris system that has a network connection to gatekeepers.
