Solved Uverse VDSL with router behind gateway... phone can't call AT&T support (or any AT&T phone?)
Recently ran into a unique problem on a home network... the phone wouldn't call certain numbers.
I dialed AT&T support 800-288-2020 dead silence.
Tried again but accidentally dialed 800-228-2020 and got antiques.com.
It turned out most were AT&T numbers and many technical support numbers even those for AT&T, Comcast, MCI... (I guess that way they limit competition and reduce complaint calls)
AT&T "talked" (forced) her to VDSL UVerse saying phone + internet was cheaper than internet only.
They upgraded from 2701HG-B ADSL2 gateway to a new 5031NV.
Network includes Linksys WRT54G router w/ddwrt firmware in DMZ providing subnet/VPN for office.
The 5031NV was public for entertainment and kids.
Earlier I swapped the WRT54G with a switch to let the 5031NV handle all traffic but network slowed to a crawl and crashed every few hours so I replaced the WRT54G. (didn't know about phone problem then)
AT&T sent a tech who verified phone problem, checked everything, exchanged 5031NV and left.
Half hour later I checked and problem was back.
I changed the WRT54G to Access-Point only mode. It handles most of the WiFi traffic.
Lose security of extra firewall/nat/VPN but stability and speed improve... and phone works!
Thank you for sharing that solution with us. We are still working towards finding a solution where you can still setup your secondary router as a router. Currently, we are not able to simulate this issue, but we are still looking into all possible avenues. It does not appear to happen with all routers.
If you encounter any issues with your service or equipment, I recommend checking out our Troubleshoot & Resolve solutions to help diagnose the issue.
