Abstract
Methods, systems and communication nodes for protecting Session Initiation Protocol (SIP) message payloads are described. Different protection techniques can be used to protect SIP payloads depending upon, for example, whether a recipient client application resides in a user equipment or an application server and/or whether a recipient client application resides in a same SIP/IP domain as the target SIP application server which is sending the SIP payloads.
