  • Patent number: 8275113
    Abstract: A method is disclosed that provides the sharing of a station-mapping description with a first private-branch exchange, where the description has been initialized and maintained at a second private-branch exchange. Such a description describes a logical association between a station extension of an enterprise deskset and a telephone number of an off-premises terminal, such as a cell phone. As a result of the sharing across private-branch exchanges, an incoming call from a second employee's cell phone can be recognized, by a first employee being called, as coming from the calling second employee. This is because the incoming call is identified with the telephone extension of the calling employee's deskset terminal in spite of the call being placed from the cell phone, or other telephone number at large. This is particularly important where a large company engineers its enterprise's telecommunications system across multiple private-branch exchanges.

  • Patent number: 8265038
    Abstract: Techniques for use in a network processing component is for initially establishing, via a gateway, a voice call between a mobile device which operates in a wireless network and a destination device. A first connection leg of the voice call is to be established between the mobile device and a conference room of the gateway. The technique involves sending to the gateway a request message for establishing a second connection leg between the network processing component and the destination device, and then subsequently sending to the gateway a re-routing message for re-routing the second connection leg from the network processing component to the conference room. This causes a voice call having the first and the second connection legs to be initially established between the mobile device and the destination device via the gateway.
