Need some tips (if any) for using VOIPo over a Uverse Pro (3.0 Mbps) internet connection. This is for my parents, and they live an hour away, so I would like to do the research before I get there.

My mom was shipped a Grandstream ATA. This is what I was planning on doing.

1. Assign static IP to the ATA inside the Uverse RG
2. Forward UDP 5000-65000
3. Forward Uverse calls to VOIPo number in order for my mom to get a feel of the VOIPo service before porting completely to VOIPo.

The ATA will be hooked up directly to the RG to one of the LAN ports.

Anything else I need to be worried about? Thanks!
