Multitype SIP processing element

摘要

The present invention relates to a proxy for a signalling protocol, and more particularly to a SIP proxy. The proxy (1) comprises a component for a context-full proxy signalling mode (5) and a component for a context-less proxy signaling mode (4). The proxy further comprises a control means (7) to change between context-less and context-full mode of operation, and a protocol evaluation means (6) to evaluate received protocol requests. The protocol evaluation means (6) is configured to detect the reception of a proxy mode change request and to signal the control means (7) to change the proxy mode depending on the received proxy mode change request.
