Does anyone know if there is a maximum distance for an ooma to be from the router before I notice a degradation in the phone quality? My computer and stuff are in another part of the house, and I'd like to use Ooma to replace a home office line, but it means I'll have to run the ethernet cable from the router, up through the ceiling, about 30 feet, then down the other wall... so approximately 50 ft of ethernet cable between an ooma and the router...

Thanks in advance!

50' shouldn't be a problem as long as you use quality LAN cable.
CAT 5E or CAT 6 cable will work.

Rock and roll!

Thanks for the info... if anyone looks this up in the future:

The maximum allowed length of a Cat.-6 cable is 100 meters (330 ft) when used for 10/100/1000BASE-T. This consists of 90 meters (300 ft) of solid "horizontal" cabling between the patch panel and the wall jack, plus 10 meters (33 ft) of stranded patch cable between each jack and the attached device. Since stranded cable has higher attenuation than solid cable, exceeding 10 metres of patch cabling will reduce the permissible length of horizontal cable.

According to the ANSI/TIA/EIA standard for category 5e cable, (TIA/EIA 568-5-A[5]) the maximum length for a cable segment is 100 meters (328 feet). If longer runs are required, the use of active hardware such as a repeater, or a switch, is necessary.[6] [7] This 100 meter limit is all inclusive. According to some authors[who?], the practical limit for permanently installed cable is about 90 meters, leaving 5 meters at each end for the patch cables that connect the end equipment to the wall panel.
