摘要 |
A method provides call pickup in a communications network. The method includes initiating a call from a first device to a second device. The call is initiated over one or more networks, where at least one of the one or more networks includes a data network. The method further includes storing information relating to the call initiation between the first device and the second device, receiving a message from a third device during the call initiation, where the message includes a call pickup indication, retrieving the information relating to the call initiation between the first device and the second device, and establishing a call between the first device and the third device based on the retrieved information.
