Here's how it's setup.
My parents swtiched from normal DSL/POTS service to u-verse DSL and u-verse voice back in December. U-verse internet is working great, however I've had trouble with u-verse voice since it was self installed. My parents have quite a 8 phone jacks hooked up to the u-verse voice line. However only two phones are hooked up to it. One upstairs in the master bedroom and one in the kitchen with DSL filters attached to each phone. The residential gateway is in my brother's room as that is centrally located in the house which provides good wifi coverage. The RG is connected to the wall jack with the dual filter (one for data and one for phone). I have the data line (green) connected to the proper slot (listed as "phone" on the RG with a green square around the input). For the voice service, I have normal phone line cord that runs from the RG to the dual filter. Now I am able to get voice on the phone jacks throughout the house, however when my parents are actually using the voice service, after a period of time while in the middle of a phone conversation the static appears. I don't know why this is happening but it is. I should also point out that on the external telephone box on the house, the line is connected. Now when I followed the instructions, I was told to disconnect the phone line at the external telephone box. However when I've done that, both u-verse voice and internet does not work. I don't know if it's something I screwed up on the install or is it a bad RG. Also I should note, caller ID doesn't work on the phones connected to the wall jacks. However if I connect a phone directly to the RG, it works fine. Any advice would be greatly appreciated.

You have narrowed it down to that - confirmed that - by saying there is no static when a "good" phone is the only thing connected to the dial tone source. That is a small perfect analog circuit.
Then, you plug in to a wall jack. Behind the wall is unknown. The troubleshooting technique is an extension of "just the RG".
Isolate & add known pieces.
First, you should not need filters. If you wire NID to RG direct - no other connection - you do not need filters. It is only if you are using the same circuit for U-verse feed and telephone service would you use filters.
Second - yes you want to disconnect the analog telephone from the NID. It is two wires. If you are disconnecting four wires, that would be why you are disconnecting U-verse. You have to keep the two that are U-verse & only disconnect the tel connection.
Third, do the phone wires all come together at a bunching block? This gives you the opportunity to disconnect each telephone set leg at a time to find out which one it is.
Hopefully, you do not get to step three. You are static free after step two.

Probably too late for the OP, but in case anyone else is having the same issue:
During the self-install process, a technician came out to your house and hooked up all of the telephone lines inside the DEMARC (external telephone box) to a grounded protector which then connects those lines to the outside telephone network. What this means is that all of the telephone lines in your house are sharing the same electrical circuit and that you are back feeding the dial-tone off of the residential gateway along the same circuit as the VDSL signal coming in. This fact is almost certainly the cause of your static. What you need to do to resolve the issue is isolate the VDSL and Dial Tone circuits. Options:
1. If you or someone you know knows what they are doing, you can replace the jack where the RG is located with a 2 port jack and use a non connected pair to backfeed the Dial Tone to the other jacks. If all of the lines feeding all of the jacks run to a single location (the DEMARC, a smart panel, punch-down block, etc.) this is relatively easy, but you will still have to isolate the VDSL line and do some minor splicing. Otherwise you will likely end up running a new line.
2. You can use a wireless phone system and plug the main base directly into the Residential Gateway and then use the sattelites throughout the house.
3. You can bite the bullet and pay whatever fees are required to have an AT&T technician come out and do (1) for you.
I believe that (2) is less expensive than (3), but the static could also be an indication of some other type of trouble instead/also and (3) will give a trained technician the chance to correct this.
