Title: Method for network-based remote IMS CPE troubleshooting

Abstract: A method for use in an IMS VoIP Network provides for remote troubleshooting of a CPE problem. After receiving a customer complaint, customer care begins the troubleshooting process, collecting and compiling information to send to the test platform. The test platform constructs a SIP test call request instruction and sends it to the CPE. The process is repeated for a number of test calls. If there is no response from any of the test calls, it is concluded that the CPE is in trouble. The results are reported to Customer Care Center, which can use those results to take action to resolve the problem. In another embodiment, after failure of all of the test calls, another SIP instruction is sent to run diagnostics on the CPE. The diagnostic results are reported to Customer Care Center, which can take action based on those results to resolve the problem.
