  • Routing calls in a network
    Patent number: 8737592
    Abstract: A method includes receiving a telephone number mapping query associated with a call. The method may also include generating routing information based on the query and forwarding the routing information to a control device. The routing information may indicate that processing associated with routing the call is to bypass a core portion of an Internet multimedia subsystem (IMS) when a calling party associated with the call does not invoke an IMS service, the called party associated with the call does not invoke an IMS service and the called party is not an IMS subscriber.

  • Telephone system and method for reliable emergency services calling
    Patent number: 8515019
    Abstract: A method of routing a telephone call includes receiving an indication, at a handset device 112, to initiate a telephone call. It is then determined, preferably by the handset device 112, whether the telephone call is an emergency services telephone call. If the telephone call is not an emergency services telephone call, it is routed to a proxy server 134. On the other hand, if the telephone call is an emergency services telephone call, it is routed to a local gateway 116 without first accessing the proxy server 134.
