ABSTRACT:
The present invention is directed to processing calls to busy telecommunications lines. In one embodiment, the presence of a subscriber accessing a computer network over a first telephone line via a first computer terminal is detected, wherein the subscriber also has a first telephone station connected to the first line. When a caller calls the first line and the first line is busy, the call is forwarded to a second telephone line associated with a call manager system. The call manager system determines when the subscriber is no longer accessing the computer network. At least partly in response to determining that the subscriber is no longer accessing the computer network, the call manager system transmits a text message to the caller, the message including the subscriber's phone number. The caller can then call back the first line using the transmitted phone number.
