  • Method and apparatus for assigning a virtual number during porting of a primary number
    Patent number: 8570906
    Abstract: A method and apparatus for enabling a network provider to instantly assign a virtual number to a subscriber to use until their primary number is successfully ported to the VoIP network is disclosed. For example, a virtual number can be a phone number for callers outside a subscriber's local calling area to call the subscriber for the price of a local call if the subscriber chooses a virtual phone number in their local calling area. After the porting of the primary number is successful, the user can be reached by either having callers directly dial the primary number or the previously assigned virtual number. The subscriber can continue to use both phone numbers or choose to disconnect the virtual number and only use the successfully ported primary number.

  • Decomposed H.323 network border element for use in a voice-over-internet protocol network
    Publication number: 20050125696
    Abstract: A decomposed H.323 border element is disclosed that is useful for providing an entry point from one or more H.323-based networks into a SIP-based VoIP network. In one embodiment, the signaling element of the BE is separated into a separate functional entity from the media control element to facilitate a single signaling entity controlling multiple media entities. In another embodiment, the security element of the border element is also separated from the media control element so that firewall and network address translation elements may be performed by a separate functional entity. In a further embodiment, the media transcoding element is separated from the media control element. In a final embodiment, the internetworking facility between the SIP and H.323 element is separate from the H.323 gatekeeper elements.
