I have the Ooma Telo plugged into the back of my Uverse Res. Gateway, and the line 1, line 2, voicemail icon, trash icon, play and forward icon are all lit up and the logo is blinking red.
I first tried it with the standard Uverse Firewall settings, and then I followed the instructions on another post to open up the UDP and TCP port ranges. I also tried using the Telo as the Uverse "DMZPlus" device...but none of these options have worked!
If so, did you connect your landline to the Wall port of the Telo?

No, I didn't activate in landline integration mode. I did receive a temporary number. I let the unit stay on overnight, but it still looks the same...flashing red logo. I've rebooted the Residential Gateway (integrated modem and router) as well as the Telo each time that I changed firewall settings, and I waited at least 15 minutes before trying new settings each time.
I'm open to suggestions! Thanks much
