  "abstract": "Sharing wirelines using a network node device includes receiving a second telephone call, while a first telephone call is in progress, and allowing one of the handsets to pick up the second telephone call while the first call proceeds in parallel. Further a call can be placed across a wireline shared by at least two billing entities.",
  "claims": [
    "1. A method of receiving a second telephone call, while a first telephone call is in progress through a connection with a first wireless device associated with a single, common telephone identifier, the method comprising: routing the second call to a telephone wireline connected to a network node device, the telephone wireline being a routed-to telephone wireline; dynamically associating said routed-to telephone wireline with the telephone identifier; notifying users of at least one wireless device associated with the telephone identifier, of the second telephone call; receiving a connection request from at least one second wireless device associated with the telephone identifier; initiating a connection between the network node and the at least one second wireless device making the connection request; and accepting the second telephone call as associated with the telephone identifier so that the second and first telephone call are connected in a common connection.",
    "2. The method of claim 1 where the notification of users includes a tone inserted into audio stream of the first call in progress.",
    "3. The method of claim 1 where the notification of users includes initiating connection with other wireless devices associated with the telephone identifier, and providing notification through them.",
    "4. The method of claim 1 where the notification of users includes audible indications.",
    "5. The method of claim 1 where the wireless device requesting connection with the network node device is a wireless device engaged in the first call, the method further including placing the first call on hold while the user is speaking on the second call."
