Abstract
A telephone call management system first receives a call over a telephone network from a calling device. The calling device is connected to a first called device by a first connection through the telephone network. A first call management message is received at a call routing engine, the first call management message to cause the engine to initiate establishment of a second connection among the calling device, the first called device, and a second called device. The engine issues, in response to the first call management message, a second call management message specifying a DTMF sequence for provision to the telephone network to cause the telephone network to establish the second connection. The telephone network may be a public switched telephone network.
