Maybe the most of the primary media gateways for EAST are clustered closer to the EAST servers and CENTRAL to the CENTRAL servers etc. I've never had failed calls, only audio issues, and was told by support that moving me to EAST servers should help since ping and traceroute were much better. Vonage did the same thing ... when audio was bad they would switch you to a different server.
