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 packet network via a first gateway, connecting an entity to the packet network via a second gateway; transmitting data over the packet network between said coding-decoding unit on a first side of the packet network and said 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 from the first gateway to the second gateway 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, when such data frames are either received from said entity or producible using at least information received from said entity, said data frames carrying coded data and signaling information relating to tandem free operation, and the coding of the coded data in the data frames corresponding to the decoding capabilities on the first side; wherein said first gateway comprises a media gateway and a media gateway controller, and said information is transmitted from the media gateway controller to the second gateway.
