1. A method performed by a first computing device, the method comprising:
receiving registration in a wireless communication network;
establishing a real-time person-to-person media session over the wireless communication network with a second computing device;
performing a handshake procedure with the second computing device using at least one Real-Time Transport Protocol (RTP) header extension, the handshake procedure performed to determine whether the second computing device supports exchange of status messages between the second computing device and the first computing device;
generating a status message, the status message comprising status information of the first computing device; and
responsive to determining that the second computing device supports exchange of status messages between the second computing device and the first computing device, sending the status message to the second computing device through the wireless communication network.
