SIP over Uverse
I recently relocated to the US and as a result my company also provided me a vOIP account through "ISphone" a VoIP provider in Australia.
When I got to the US I got connected to Uverse AT&T, everything was fine except the bit when I connected my Cisco SPA200 device along with my registered VoIP account which I believe uses the SIP gateway protocol did not work. The device would just not register or give me a dial tone.
I have done all the things necessary in relation to port setting , enabling of firewalls, Contacting AT&T and have now concluded that the problem is with the U verse 2wire router.
I also paid 50$ for techs to help me out but in vain. I strongly believe there is an issue with U verse Router not recognizing the SIP gateway.
IS there any device available out there that could convert SIP to a different VoIP protocol .I suspect the U-Verse is probably having problems running any SIP-based VOIP service as these ports are trapped by the RG.
Your Uverse router+modem combo (AKA residential gateway) only provides communications.
If you have a box that is supposed to do your communications for you, I would start by setting your Uverse gateway to put that box in the DMZ. Test that way. The gateway will forward all incoming ports to your box.
Then later open just the needed ports to your box.
I suggest setting the RG to always give the SIP box the same DHCP IP to make pinging or accessing that box's web server easier and consistant.
I use the OBi202 box to do SIP with the Uverse gateway. No problems. I did not have to make any adjustments, although I did have to make settings to protect against SIP scanners. (search that term).
I suggest posting into »VOIP Tech Chat if you have problems communicating with your SIP box in the DMZ.

I have a Magic Jack. It works fine. You didn't specify your modem, but I have a 2wire 3600. In order to get the Magic Jack to work flawlessly, I went into the device and forwarded port 5060 and 5070 to the computer that housed the MagicJack usb device. You do say you have a two wire, so yours should be similar.
When setting up the forwarding, there was the choice of indicating what kind of application was involved, and I chose "SIP-based Internet telephony". This seems to handle the myriad amount of other ports that Magicjack uses to handle the audio.
Works as good as POTS.
You'll have to consult your VOIP provider to figure out what ports to forward. If this "Cisco SPA200" is some sort of router, then you could go into the modem and place this in the DMZ, and then hook your computers to the Cisco SPA200 and handle your routing issues from the Cisco SPA200.
But, if it was me, I would just set up the telephone adapter with the appropriate port forwarding and hook the computers to the modem. First, figure out the ports. If your provider doesn't give you good information then use the ports I'm using. Go into your modem settings and look for an " Applications, Pinholes and DMZ" page, choose your Cisco device and click on "Add a new user-defined application". You'll get into a page to add the ports. Select UDP and 5060 to 5060, leave the next two items blank and for application type, choose "Sip based internet telephony".
The port you added should show in the:
"Protocol Port (or Range) Host Port Timeout (sec)
entry near the bottom of the web page.
The web page should be blank so you can add an additional port. Add any other ports. In the case of magicjack I added 5070 and again selected "Sip based internet telephony". Once I was done, I then hit the "Back" button.
Make sure under "Select a Computer" that your Cisco device is selected. Once it is, then go to the Application List and select the Cisco entry you created and add it to the "Hosted Applications" list.
Click on the "Save" button near the bottom and hopefully, it will work.
Unless you put a router in DMZplus mode and pass the IP to the device, you will have issues with voip. I have a nettalk adapter that won't work unless I have it behind my DMZ device/router. I think the gateway has it's own traffic QoS to give your TV/Phone(whether you have service or not) priority, any device that runs on similar ports/protocols suffers unless you have it behind a DMZplus device, and set your own ports/QoS for the device.
