A method is provided for invoking call features to be executed in a session initiation protocol (SIP) environment, the method comprising: receiving a signal indicating a feature activation; and inserting a call information header into a SIP message, the call information header comprising a parameter that identifies the activated feature. Alternatively or additionally, a method is provided for controlling a user interface coupled to an endpoint in a SIP environment, the method comprising: receiving a SIP message comprising a user interface parameter carried in a call information header; and modifying the user interface to reflect the value of the user interface parameter. In yet another alternative, a method is provided for communicating user interface information to an endpoint in a SIP environment, comprising: creating a SIP message comprising a user interface parameter in a call information header; and transmitting the SIP message to the endpoint.
