Input: I have had no luck in getting the modem to work.  It sets up ok and responds to AT commands until it is asked to dial.  It immediately returns ERROR.  I have worked with the vendor service desk for over a month.  I  have tried two Macintoshes and a PC.  I've tried 3 different phone lines  and paid the phone company to check the lines at my house.  I have edited  CCL files.  I have had two engineers and a computer technician try.  I have  swapped the modems with other modems known to work and they all work fine,  but the Zoom doesn't.  Amazon's wonderful replacement policy replaced the  first modem.  The second modem does the same identical thing.  I have spent  too much time and money on something that is supposed to plug in and  operate easily.  I'll try something else.
