  • System and method for session initiation protocol header modification
    Patent number: 8416780
    Abstract: A method for modifying the contents of session initiation protocol (SIP) messages is presented. The method includes receiving a SIP message. The SIP message may include a set of message header fields. The method includes receiving an application policy. The application policy may specify how to modify the SIP message based on a characteristic of the SIP message.

  • System and method for integrating an outgoing cellular call as an enterprise call
    Patent number: 8265614
    Abstract: In one embodiment, a network node is operable, responsive to receiving a request from an enterprise user to initiate origination of an outgoing cellular call to a called party, for establishing a first call leg to the enterprise user by sending a circuit-switched call that identifies an enterprise address of the enterprise user as a calling line identity. The network node includes functionality for establishing a second call leg to the called party upon receiving an indication from the enterprise user that the first call leg has been established. The first and second call legs are then patched to establish an end-to-end communications path between the enterprise user and the called party, wherein the enterprise address instead of the non-enterprise address is presented to the called party as a calling line identity with respect to the outgoing cellular call from the enterprise user.
