ABSTRACT:
A method for transmitting voice data over various types of networks wherein user data are transmitted via a transmission link of a circuit-switched network and are distributed to data packets and forwarded via a packet transmission network if the user data are typical of voice transmission. If, in contrast, the user data are typical of silence intervals, no user data are forwarded via the packet transmission network. The type of connection is determined in a signaling unit.
