Abstract
Systems and methods of configuring an add-on device to augment the capability of existing endpoint infrastructure are disclosed. In one embodiment, a video add-on device is configured to receive, augment or downgrade, and forward messages for an existing SIP audio-only phone. The video add-on device in this embodiment can receive messages from the existing SIP audio-only phone and augment the messages with information regarding the additional video capabilities being provided. The messages can then be forwarded to an infrastructure SIP Proxy/Registrar for further routing. From the perspective of the infrastructure SIP Proxy/Registrar and other network attached devices the outbound messages from the video add-on device appear as if they originated from the video add-on device, other devices will not be directly aware of the existing SIP audio phone providing its designed function. Utilizing devices similar to the disclosed video add-on device may allow incremental corporate network endpoint upgrades.
