Abstract:
1. A method for transmitting information related to tandem free operation, comprising: connecting a cellular network comprising a tandem free operation capable coding-decoding unit to a first side of a packet network via a first gateway; transmitting data over the packet network between said coding-decoding unit on the first side of the packet network and an entity on a second side of the packet network; transmitting information about the decoding capabilities and tandem free operation capabilities on the first side of the packet network over the packet network to the second side of the packet network for enabling on said second side of the packet network transmission of data frames to the packet network, said data frames carrying coded data and signaling information relating to tandem free operation, and coding of the coded data in the data frames corresponding to the decoding capabilities on the first side; wherein said information is transmitted by at least one element selected from the group consisting of: a media gateway comprised in said first gateway and a media gateway controller, and said information is transmitted from the media gateway controller to a second gateway on the second side of the packet network.
