Call management using call routing engine

A telephone call management system, comprising:

• means for receiving a call over a public switched telephone network from a calling device;
• means for connecting the calling device to a first called device by a first connection through the public switched telephone network;
• means for receiving a first call management message at a call routing engine, the first call management message to cause the engine to initiate establishment of second connection among the calling device, the first called device, and a second called device;
• and
• means for issuing from the engine, in response to the first call management message, a second call management message specifying a DTMF sequence for provision to the public switched telephone network to cause the public switched telephone network to establish the second connection.
