Voice over IP system recovery apparatus for service and packet groups based on failure detection thresholds
First Claim
Patent Images
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.

Abstract
A system comprising a SIP failure chandler, wherein the SIP failure handler monitors SIP failures and issues an alert and reroutes call traffic based on a service group number if a SIP failure threshold is exceeded wherein the service group number is associated with a detected failure, where the service group comprises a plurality of IP addresses.

14. A method of routing calls based on a service group number where the method is performed on a cellular processor comprising the steps of:
-
monitoring SIP failures that occur during call setup; issuing an alert and rerouting 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 receiving 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. - View Dependent Claims (15, 16, 17, 18, 19, 20)
