ABSTRACT:
A system and method for concealing an identity by receiving a Session Initiation Protocol (SIP) message, the SIP message containing a field, the field containing a Globally Routable User Agent Uniform Resource Identifier (GRUU) identifying a node, the GRUU containing a public user identity (PUID), a ‘gr’ parameter, and a ‘gr’ parameter value; evaluating a subscription option; and in response to evaluating the subscription option, concealing an identity of the node by removing the ‘gr’ parameter and the ‘gr’ parameter value from the field.
