Example methods and apparatus to communicate media across different networks are disclosed. A disclosed example method involves storing via a first network device in a first network a first descriptor in a first data packet. The first data packet is then communicated to a second network device in a second network. A second data packet is then received from the second network device, and the first descriptor is compared to a second descriptor from the second data packet. When the first descriptor matches the second descriptor, an internet protocol address of the second network device is communicated to a communication source to cause the communication source to bypass the first network device and to communicate data to the second network device without passing that data to the first network device.
