Abstract: A method and computer readable medium for providing Enterprise conferencing is provided. In an exemplary embodiment of the invention, a first SIP INVITE message is exchanged between a Media Gateway of the Enterprise and a first Media Server of a Conferencing Service Provider. Then, an Application Server of the Conferencing Service Provider establishes conference call resources at the Conferencing Service Provider. A first RTP session is established between the Media Gateway and the first Media Server, and then a PROMPT AND COLLECT message is sent from the Application Server to the first Media Server to gather data from the caller for establishing the Enterprise conferencing. After receipt of the data by the Application Server, an SIP INFO message is sent from the Application Server to a second Media Server of the Conferencing Service Provider, selecting the second Media Server to host the call.

Abstract: A system, method, and computer readable medium comprising instructions for establishing a conference call comprising sending a first SIP INVITE message from a Media Gateway to an Application Server, sending a second SIP INVITE message to a first Media Server, establishing a session between the Media Gateway and the first Media Server, sending a third SIP INVITE message from the Application Server to a Conference Controller, allocating resources related to the conference call by the Conference Controller on a second Media Server, requesting by the Conference Controller for the Application Server to move data related to establishing the conference call from the first Media Server to the second Media Server, sending a fourth SIP INVITE message by the Application Server to the second Media Server and sending a SIP RE-INVITE message by the Application Server to the Media Gateway, and establishing an RTP session between the Media Gateway and the second Media Server thereby establishing the conference call.

Abstract: A hydraulic underreamer for enlarging a wellbore includes improved packer, cutting, jet pump, and mill sections. Each of the sections and their associated advantages are described herein in detail. The packer section is designed to minimize wear on its sealing elements, the cutting and jet pump sections are designed to minimize pressure requirements and optimize hydraulic efficiency, and the mill section has a removable center assembly which allows effective well control when pulling the underreamer out of a “live” well filled with a gas, such as methane.
