Shortcut phone number to connect DNS with DirectV

Update:
For any of you who find yourselves in my position, I have acquired 3 phone numbers. Since I am in no great rush to get the DNS turned on by Sept first, I have not yet called. Still have to expect to spend a ridiculous amount of time on the phone to get it finalized. I plan to do so next week.

Tech Assist 800-676-3169
DNS (been told) 806-444-7931 or 806-444-7810.

As DJT famously says, "We'll see".
