1. A system comprising:

  • a cellular processor;

    wherein the cellular processor monitors SIP failures that occur during call setup;

    wherein the cellular processor issues an alert and the system reroutes call traffic based on a service group number if a failure threshold for call setups is exceeded wherein the service group number is associated with a detected call setup failure wherein the call setup failure indicates that an attempted call has not been completed;

    wherein the service group number identifies a service group where a service group comprises a plurality of IP addresses that are used in support of the call setup; and

    the cellular processor receives the service group number in a failure message where the service group number is the service group over which the call could not be setup, where the failure message indicates that the call failed during setup.
