ABSTRACT:
Devices, softwares and methods can establish an IP connection with each other through a network. Dynamic connection attributes of the called device are inferred locally by the calling device. These may include any one or more of type of codec, bandwidth, port number, and so on. A rule may be used for inference, expecting that the called device uses the same rule. Setup takes place without the calling device receiving this information explicitly by signaling. Plus setup may take place even though expected handshake signals might not be transmitted at all, due to differences in implementation, or even a difference in protocols.
