Why can't my phone register when using OpenDNS?

If you are using OpenDNS, and have the category of Infrastructure blocked, your phones will resolve to an incorrect IP Address. OpenDNS recommends adding the domain outboundproxy.com to the "Allow List," "Never Block" List or not to block the Infrastructure category.
A packet capture that is filtered on 'DNS' from the phone or customer's Network will help us identify if this is the problem.
