Could somebody offer a brief list of telephones which will *not* be reported correctly (i.e. will people using PBX's have their number displayed properly? What about people calling long distance through various long distance companies? Are there other exceptions within the local dialing area? And do I get just the last seven digits, or area code too?) 2. With Call Waiting, my phone conversations are interrupted with two brief beeps when somebody's trying to call me. Suppose the telephone company wanted to replace those smooth-sounding beeps with FSK data bursts containing the number of the person calling. Would it entail an extensive modification to their equipment? Given the amplitude levels required by the decoding equipment, would the new "beeps" be too loud or "rude"? And if I was in the middle of a sentence when the FSK tones arrived, would the decoder be able to read them? Just curious. Thanks for any and all responses.
