  • Publication number: 20120082154
    Abstract: A call manager uses a call management application in conjunction with a live dial database to control routing of calls for managed devices. To generate the live dial database, the call management application accesses configured route patterns and enters these patterns into the live dial database. Upon identifying an expansion indicator in a configured route pattern, the call management application accesses dial plan data that includes multiple route pattern definitions that each define a pattern using one or more sub-strings and, for each sub-string, an associated tag. The call management application then enters patterns defined by the route pattern definitions into the live dial database based on various other criteria established for the configured route pattern having the expansion indicator.

  • Patent number: 8116769
    Abstract: Anchoring a communication session for a target mobile phone includes identifying a current access node operable to provide the target mobile phone access to a first network of a first network type. Potential access nodes operable to provide a mobile phone access to a second network of a second network type are identified. Whether the communication session can be handed off to a potential access node of the one or more potential access nodes is established. Anchoring of the communication session is initiated in the second network only if the communication session can be handed off to a potential access node of the one or more potential access nodes.

  • Publication number: 20110264814
    Abstract: A method for implementing a SIP feature includes, in particular embodiments, establishing a communication session via a communications platform between a first and second user and receiving a request from a third user to join the communication session. The second and third users are from a plurality of users using a shared line. The method further includes integrating communications of the third user into the communication session. In particular embodiments the method includes establishing a communication session between a first and second user via a communications platform. The method also includes receiving a select request that locks the communication session so that a third user cannot resume the communication session with the first user. In particular embodiments the method includes receiving a request from a first user of a shared line to enable a privacy feature that reduces call information generated by the communications platform in remote state notifications.

  • Patent number: 8000710
    Abstract: A method for facilitating communications between wireless networks is provided that includes communicating with a mobile station and transferring a communication session from a first wireless link to a second wireless link. The mobile station is operable to negotiate a first wireless link with a first wireless network, to establish a communication session with a device using the first wireless link, and to facilitate a session handoff with a second wireless link with the second wireless network using the second wireless interface. The handoff is enabled by associating the first wireless link to the second wireless link.

  • Patent number: 7995559
    Abstract: In one embodiment of the present invention, a method is provided for redirecting a session established between two endpoints. In such an embodiment, the method comprises receiving a SIP request to redirect the session to a third endpoint; dissociating the two endpoints; suspending a media session between the endpoints; connecting a signaling session between one endpoint and a third endpoint; and connecting the media session. In an alternative embodiment, a method is provided for referring a first endpoint to a second endpoint outside of an established dialog. In such an embodiment, the method comprises receiving a SIP REFER request specifying a uniform resource indicator associated with the second endpoint as a target; identifying a protocol associated with each endpoint; initiating a session with the first endpoint using an appropriate protocol; receiving media control information from the first endpoint; and connecting the session to the second endpoint using an appropriate protocol.

  • Patent number: 7974277
    Abstract: Routing calls includes receiving a call request at a call manager from a first endpoint. The call request includes a uniform resource identifier that associates with a second endpoint. A determination is made whether the call request associates with the call manager that received the call request. To route the call request, the call manager searches a call search space for a match to the call request. The call manager communicates the call request to the routing target.

  • Patent number: 7899175
    Abstract: A method to be executed in a session initiation protocol (SIP) environment is provided that includes initiating a conversion process that involves a change from a first communications platform to a second communications platform. One or more routing tables associated with the first communications platform are then dumped. A conversion script is executed such that one or more patterns associated with a dial plan corresponding to the second communications platform are provided in a dial plan format. One or more files associated with the dial plan are loaded into one or more endpoints that are designated to change to the second communications platform.

  • Patent number: 7877086
    Abstract: Gathering location information from a first wireless network to determine whether to anchor a communication session in a second wireless network, a mobile node capable of communicating with both the first wireless network and the second wireless network, includes receiving location information from the first wireless network as the mobile node moves through one or more service areas of the first wireless network. It is determined whether a triggering event occurs. If the triggering event occurs, the location information is stored to determine whether to anchor a session in the second wireless network.

  • Publication number: 20100226364
    Abstract: A system for device registration replication in a packet-based network includes a first call manager and a second call manager that are coupled to the packet-based network. The first and second call managers each control one or more devices and store composite registration information associated with the devices. The first call manager communicates status information to the second call manager in response to a change in the control status of a device controlled by the first call manager. The second call manager updates the composite registration information stored by the second call manager in response to receiving status information from the first call manager.
