AT&T E2811 2.4 GHz 1-Line Cordless Phone

Efficient product but keep other e-devices at least 6 ft away especially during initial setup when signal between base unit & 2nd handset must be established; Ringer choices sound like professional office phones; Handsets flash pretty lime green lite when calls come in; Name directory auto-sorts entries in alpha order; Would be nice if directory would allow 2-3 lines for address, store hrs, jots; During remote access to voicemail, the system provides pre-programmed voice prompts after you pause for 4 seconds, so, you don't have to memorize all the codes for navigating messages; Clear sound quality has not yet presented any radio interference or "junk frequency" in my NY City locale, so far; Digital Spread Spectrum Frequency Hopping technology was proposed by the US military & 2.4GHz is a good range for an apartment building, small office, small retail store, sm-med size house if 2nd handset w/b kept in nearby garage, tool shed, greenhouse within 1/2 mile; However, a very spacious estate having 1 mile or more betw affiliated buildings, should probably consider a 5.8GHz cordless phone instead;
