Method and system for performing SIP loopback in communication devices

摘要

A system operator provisions, or loads, a user's communication device, such as a cable modem, with multiple sets of loopback mode parameters that each facilitate a loopback test, and associates each set with multiple loopback numbers, or variable values. The loopback variables may be MIBs assigned to the device's manufacturer for use in initiating a loopback test of a user device. An operator may initiate a loopback test from a central computer device located remotely from the user device. The initiating device may be coupled to an operator's private IP network, or to a network coupled to the user device. The initiating device sends one of the loopback values in a SIP Invite message to the user device, without the use of SIP extensions, in a call. The user device recognizes the loopback value, auto-answers the call, and performs actions according to the provisioned parameters corresponding to the loopback value.

1. A communication device loopback method, comprising:
provisioning the communication device with one or more loopback values over a voice over internet protocol (VoIP) network assigned using a management information base object stored on the communication device, the communication device operating on a data over cable service interface specification protocol on a hybrid fiber-coax network, whereby the provisioning occurs during initialization with the hybrid fiber-coax network using the management information base object to assign the one or more loopback values to the communication device; associating each of the one or more loopback values with a loopback mode using standard session initiation protocol commands and without the use of session initiation protocol extensions; and originating a call to the device on the hybrid fiber-coax network using standard session initiation protocol (“SIP”) commands by sending a SIP Invite message over the hybrid fiber-coax network to the communication device, and using one of the loopback values assigned to the device based upon the management information base object in a calling number identifier included in the SIP invite message, wherein the SIP Invite message does not use SIP extensions.
