I've had a similar problem. I still have an 811 and a 211 hooked up to the same phone line. Most of the time, the 211 doesn't show anything except "Unknown", while the 811 has full caller data. About the only time I see good data on the 211 is when the call is from an ATT/SBC sub, like myself.just upgraded from 811 to 211. caller id will not work at all. worked fine on 811. all settings are correct. any suggestions are appreciated.:
