Abstract:
1. An apparatus comprising a processor configured to perform or cause the apparatus to perform at least the following: receiving a first relay address request message from a first terminal in a private network, the first relay address request message being received through a first binding address at an interface of the private network, the first relay address request message requesting a first relay address designated for the first terminal; providing in response to the first relay address request message, the first relay address for establishing a first communication channel between the first terminal and a second terminal, the first communication channel extending through the apparatus such that the apparatus relays control signals transmitted in the first communication channel between the first terminal and the second terminal; providing a second relay address designated for the first terminal to establish a second communication channel between the first terminal and the second terminal, the second communication channel extending through the apparatus such that the apparatus relays real-time traffic transmitted in the second communication channel from the second terminal to the first terminal; and closing the second communication channel in response to an indication of establishment of a third communication channel between the first terminal and the second terminal, the third communication channel being independent of the apparatus such that the apparatus does not relay the real-time traffic transmitted in the third communication channel between the first terminal and the second terminal.
