I've had Ooma for about 10 years now, and decided to upgrade to the Telo version. Ooma has, is, and always will be my phone service of choice. I've NEVER had any issues with calls or background noise. I just connect it to my modem/router and BAM- stellar phone service. I pay $10+ per month for the premium service-- a stark contrast to paying exorbitant fees to other phone companies. With the Linx Accessory, I can now connect my fax machine wirelessly without having to connect it to the Telo device. I'm pleased with the deal I got from Groupon as well... It's a win-win no matter how you slice it. Thanks Groupon and Ooma!!
