The problem I had was, in the exchange I was in (415-655; Oakland, CA), the switch apparently was NOT actually ready to accept digits as soon as it started generating dialtone. The modem would usually fail to complete calls when in the "dial as soon as you hear dialtone" mode; I'd hear the first burp of dialtone, then the modem tones, then nothing ... my assumption was that the switch was missing the first digit or two.
