First commercial compressed speech call over an all-IP network announced
Posted: 08-Feb-2006 [Source: Ericsson]

[Ericsson and VimpelCom successfully demonstrate 3GPP standard-based compressed speech and signaling (SIGTRAN) over IP in a commercial GSM network.]

Ericsson and VimpelCom, which operates Russia's Beeline service, are the first to demonstrate 3GPP standard-based compressed speech and signaling (SIGTRAN) over IP in a commercial GSM network. Speech compression over all-IP, introduced with Ericsson's Mobile Softswitch Solution, is the fundamental first step in the migration to an efficient IP network and it greatly reduces transmission requirements. The first call was made in December 2005 between Yekaterinburg and Nizhniy Tagil in a new VimpelCom coverage area. This state of the art technology will be launched across the whole of this new region in February 2006.

Zoran Lukovic, Vice President, Market Unit Eastern Europe and Central Asia, says: "We are proud to be selected by VimpelCom for the deployment of the softswitch solution and to support its evolution to all-IP. We are also grateful for their support to achieve yet another world first, confirming Ericsson's leadership."
