Method for communicating audio data in a packet switched network |
摘要 |
A method of audio communication between a first telephony client located behind a network address translation (NAT) server and a remote second telephony client is disclosed. A calibration datagram is sent from the first telephony client to the second telephony client on a user datagram protocol (UDP) channel identified for sending audio data. The second telephony client extracts the source address and port number to identify a reverse UDP channel for sending audio data to the first telephony client.
