Abstract: The invention relates to method applicable in a packet-switched cellular network for voice connections, by which method a new dedicated channel can be established quickly using the existing dedicated channel of the voice connection. The establishment of the new dedicated channel utilizes the previous dedicated channel the existence of which is extended by sending to at least the receiving terminals post-speech packets according to the invention. The post-speech packets produce a 2-second delay, approximately, which is sufficient to establish a new dedicated channel between terminals participating in a session.
