Abstract
VoIP verification is initiated by subscriber-side test VoIP appliance, or VoIP proxy agent. Test VoIP appliance is coupled to test node over a communications internetwork by upstream and downstream datapaths. VoIP verification request is transmitted to test node. Responsively, test node transmits VoIP verification signal to test VoIP appliance. Perceivable indication of verification signal received by VoIP appliance is effected by visual display, audible indication, or both. Operational state verifier apparatus is disposed in a digital telephony device, a computer terminal, or with an ATA interface coupled to analog telephony device used in VoIP communications system.
Claims22
A VoIP appliance coupled by an upstream datapath to a test node and by a downstream datapath from the test node, the VoIP appliance comprising:
- a verification initiator configured to communicate a VoIP verification request to the test node, whereby the test node responds with a VoIP verification signal;
- and
- a verification processor configured to receive the VoIP verification signal from the test node, and further configured to provide a perceivable indication of the VoIP verification signal.
In a communications system having a test node receivingly coupled to an upstream datapath and transmittingly coupled to a downstream datapath, a VoIP appliance comprising:
- means for transmitting a VoIP verification request to the test node wherein the means for transmitting is coupled to the upstream datapath and wherein the test node forms a VoIP verification signal responsive to the VoIP verification request;
- means for receiving the VoIP verification signal from the test node;
- and
- means for producing a perceivable representation of the VoIP verification signal.
In a communications system having a VoIP appliance transmitting to a test node over an upstream datapath and receiving from the test node over the downstream datapath, a method for VoIP verification comprising:
- transmitting a VoIP verification request from the VoIP appliance to the test node, wherein the test node is adapted to receive the VoIP verification request;
- receiving a VoIP verification signal by the VoIP appliance from the test node, wherein the test node formed the VoIP verification signal responsive to receiving the VoIP verification request;
- and
- producing a perceivable representation of the VoIP verification signal at the VoIP appliance.
