Cisco CUBE: ATT SIP To Cisco Cube Router Configuration Example

One thing I have noticed is that working on a SIP config for an AT&T SIP trunk is not the same as most other providers.  In fact, its been really hard to even find a config out there to look at.  All I could find is the several hundred pages of an AT&T document.  So Im pasting my router config here in the hopes this helps someone looking for an AT&T SIP config for their CUBE.  See below.  I hope its helpful.
One thing to note is that in the dial-peers, you do not have to point to the AT&T media servers.  You only have to point your dial-peers to the SIP proxy servers.
