No. It is another seperate server that acts as the master registry and also as a central point for all our Call Records across all the slaves (plus a few other things).

The reason US users sometimes see two entries is because of yet another wrinkle called SRV records. SRV records are a special type of DNS entry that allow us to balance the load across multiple servers and support failover.

So, in the US, we have two physical servers (proxy01.us1.voxalot.com and proxy02.us1.voxalot.com). We have an SRV record for us.voxalot.com that spreads the load across those two servers, so if your ATA points to us.voxalot.com (and supports SRV records) then depending on the timing, your first device might have the SRV resolving to first US server and the second device might resolve to the second US server. In this case, because each US server is considered as a separate slave, the master shows two entries.

Does that make sense?
