  • a session initiation protocol (SIP) gateway configured to interface with a public switched telephone network (PSTN), wherein the SIP gateway translates a telephone call from a telephone coupled to the PSTN into a SIP protocol message, and wherein the SIP gateway switches the voice portion separately from the signaling information of the same telephone call;

    a SIP server coupled to the SIP gateway to accept the SIP protocol message;

    an application server configured to access a voice extensible markup language (VXML) page on behalf of the SIP server; and

    a VXML gateway configured to allow a user of the telephone access to the VXML page, wherein the VXML gateway can be de-coupled from and re-coupled to the SIP gateway during the same telephone call.
