DNS Settings

[VOIPoTim]

For the most reliable service, it's recommended that you set your ATAs to use 156.154.70.1 or 156.154.71.1 as the preferred DNS server.

This is through Neustar/UltraDNS. These will give you faster resolution times for VOIPo records by giving you direct access to them to pick up changes and it uses AnyCast routing which should speed things up some too. It'll connect to the best route for you in one of the following locations:

Ashburn VA
Chicago IL
Dallas TX
Miami FL
New York NY
Palo Alto CA
San Jose CA
London UK
Luxembourg
Johannesburg South Africa
Beijing China
Sydney Australia
Hong Kong

There are a ton of DNS queries involved even with registrations and having it set direct is not entirely necessary, but will help make sure you get any changes faster and that the response time is fast.

These will provisioned in for our provisioned users.
