摘要：
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.
