Abstract
A method for routing bearer traffic (70′) between 3G networks (32, 42) and 2G networks (12, 22) and vice versa uses voice signaling gateways (VSGW)(14, 24, 34, 44). The method determines a VSGW nearest the calling party (11). The nearest VSGW directly routes (86) the bearer traffic through the inter-network (50) to the called party (31) and avoids the “tromboning” effect of always sending bearer traffic to the called party's home location.
