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.

System and method for communicating call information in a sessions initiation protocol (SIP) environment

A method for implementing a SIP feature includes, in particular embodiments, establishing a communication session via a communications platform between a first and second user and receiving a request from a third user to join the communication session. The second and third users are from a plurality of users using a shared line. The method further includes integrating communications of the third user into the communication session. In particular embodiments the method includes establishing a communication session between a first and second user via a communications platform. The method also includes receiving a select request that locks the communication session so that a third user cannot resume the communication session with the first user. In particular embodiments the method includes receiving a request from a first user of a shared line to enable a privacy feature that reduces call information generated by the communications platform in remote state notifications.

System and method for implementing a session initiation protocol feature

A remote call control method is provided, the method comprising exchanging a session initiation protocol message, wherein the message indicates a call control request is associated with the message; identifying a resource associated with the call control request, wherein the resource includes one or more parameters of the call control request; and performing a call control operation according to the parameters of the call control request. A communication platform and endpoint are provided for executing a call control operation according to a call control request. The communication platform and endpoint comprise a processor component operable to exchange a session initiation protocol message, identify a resource associated with the call control request, and execute a call control operation according to the parameters of the call control request. The message indicates a call control request is associated with the message, and the resource includes parameters associated with the call control request.

System and method for remote call control

In one embodiment of the invention, a method produces a hook status notification. The method comprises detecting an off-hook state, allocating a half-dialog identification, generating an off-hook notification message, and associating the half-dialog identification with the off-hook notification message. In an alternative embodiment, a communication platform is adapted to comprise a processor component operable to receive an off-hook notification message comprising a half-dialog identification, and to store the half-dialog identification. The communication platform subsequently receives a signaling protocol message initiating a dialog, wherein the signaling protocol message is associated with the half-dialog identification. The communication platform then correlates the second signaling protocol message with the stored half-dialog identification.

System and method for hook state notification

A method to be executed in a session initiation protocol (SIP) environment is provided that includes initiating a conversion process that involves a change from a first communications platform to a second communications platform. One or more routing tables associated with the first communications platform are then dumped. A conversion script is executed such that one or more patterns associated with a dial plan corresponding to the second communications platform are provided in a dial plan format. One or more files associated with the dial plan are loaded into one or more endpoints that are designated to change to the second communications platform.
