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.

Method and system for performing SIP loopback in communication devices

Methods, systems, and apparatus, including computer program products, in which a call transfer can be performed independently of a positive final response in a call transfer to the a third party subject of the call transfer. In some implementations, a first party to the communications session can send a drop/disconnect signal after initiating the call transfer or after receiving an acknowledgement of the initiation of a call transfer.
