Abstract: The bidirectional IP communication device (device) broadcasts a first discovery packet for establishing communication sessions using a first network communication protocol. The device also transmits a second network communication protocol for establishing communication sessions using a second network communication protocol, where the second network communication protocol is different to the first network communication protocol. The device then receives a response to either the first discovery packet or the second discovery packet. Based on this response, the device identifies which network communication protocol is in use. The device then configures itself for the network communication protocol that it identified as being used.
