How to setup VOIPO service with AT&T U-Verse

One of the few things I found challenging with VOIPo is that they did not include any manuals or instructions when they mailed the VOIPO ATA. I am sharing the steps I used in the hopes it will save you some time.


My Equipment
  • AT&T U-Verse 3800HGV-B (any ISP Residential Gateway or router will do)
  • Grandstream HT502 (VOIPo ATA adapter) - this is what VOIPo mailed me within 3 days of signing up

Networking Terms
  • Router/Gateway: The network device that provides the Internet services into your home. Should include at least one built-in LAN port that you can link to the ATA. Can be an all-in-one device such as
  • ATA: The device you received from VOIPo. This is the unit that will serve all of your VOIP services and needs to be connected to your home network.

Resources:

Setup:

1. Connect the provided ethernet cable between your gateway/router LAN port into the WAN port of the ATA. The LAN port will not be used.
2. Plug in the provided AC adapter so the ATA turns on. Wait 1 minute for the unit to fully boot up.
3. Open a web browser and log into the gateway or router device you connected to the VOIPo box (ATA). For the vast majority of routers, the default address is http://192.168.1.1 or http://192.168.1.254. If you are using AT&T U-Verse, you can also navigate to http://gateway.2wire.net/

For steps 4-6, you need to read the manual for the router you are using. Each vendor may have different steps involved, and firmware varies as well.

4. Assign a static IP address to the VOIPo adapter.
5. Enable port forwarding and forward the following port ranges to the static IP. Make sure to forward the entire range of ports and not just the first and last port:
  • UDP 5004-65000
6. Disable the SIP ALG feature if your router supports this. The current firmware of AT&T U-verse's gateway does not support disabling SIP.
7. Check with VOIPo support if you are using other VOIP devices on your network. My setup instructions assume only VOIPo will be used to connect a maximum of two phones.

Notes:
AT&T U-verse's gateway does include a DMZPlus mode. I did not use this feature and found my VOIPo service to work perfectly fine without it.
